Environment

Exposure

Do not expose the Micro-Speed MV® to excessive vibration (not more than .5G), heat above 60°C, corrosive gases, dust, steel particles, high relative humidity (condensative), or environments where sources of electrical noise are present. A proper Nema rated enclosure should be provided when required for the application of the existing environments.

Ambient Temperature

The environmental ambient temperature for the Micro-Speed MV® should not exceed 60°C (140°F) or go below -10°C (14°F). Call Power Electronics if your application has ambient is outside this range.

Mounting

Mount the Micro-Speed MV® vertically on a panel out of direct sunlight or radiant heat with spacing that allows adequate ventilation of the heat sink. (See the Drive Clearance Chart)

Wiring Practices and System Requirements

1. To ensure that the unit is properly grounded, the heat sink must be grounded. (Use the grounding lug or grounding terminal on the Micro-Speed MV®)

2. Always branch protect the Micro-Speed MV® with fuses or circuit breakers.

3. Do not use contactors on the drive output.

4. The drive must be hard wired to the motor. Use conduit or festooning. Do not install any rails or other devices which may open the connection between the motor and the drive.

5. If not festooning, use Double Shoe Type collectors on the conductor bar.

6. If possible, try to run the motor, brake, and control wires separately.

Always use a 3-phase isolation transformer or an inductor on the input of the Micro-Speed MV® when used near equipment which intermittently draws high current, such as arc-welding or smelting equipment.

Micro-Speed MV® drives of 100Hp or larger should ALWAYS use a 3-phase isolation transformer or an inductor on the input.

Encoders should usually (but not always) be grounded to the shielding of the cable without connecting to CGND terminal on the Multi-Vector drive side. In some instances it may be necessary to ground both the drive and the encoder ends of the shielding on the encoder cable. For some encoders you may need to test all combinations of grounding or NOT grounding (including no grounding on either side) if there is an error or noise detected by the drive. If there are no ground wires on the encoder you are using, contact the encoder manufacturer for grounding information if necessary.

Suitable for use on a circuit capable of delivering not more than 5,000 RMS Symmetrical Amperes, 600 Volts maximum.

For safety reasons, always use two brake contactors in series on hoisting applications.

Mount Brake Resistors in a safe enclosure: Braking resistors can become extremely hot and have exposed high voltage connections warranting placement in a touch-safe enclosure away from flammable material. The resistors will remain electrically hot for several minutes after the power has been disconnected. Also the possibility of resistor failure is present and requires the special enclosure to prevent any molten material from causing injury or damage. PE Braking resistors are recommended.

Do not service drive until bus charge lamp is out: Before servicing, disconnect power. If the red charge lamp is still on after 5 minutes, wait until it is off. The red charge lamp must be off before proceeding further.

It is necessary to follow these precautions because dangerous electrical energy will remain in the unit even after power is disconnected .

If any questions arise, contact the factory at (888-220-9494). PE engineers will also help fit a Micro-Speed MV® to any unique or special application. Changes to the Micro-Speed MV® may be made and ordered for special uses.



Wiring

No-Load Brake Hoist Wiring Below is a typical drawing of the Micro-Speed MV® running a no-load brake hoist with multi speed pendant.

Bridge or Trolley Wiring A bridge or trolley is wired like the above hoist, except that one brake contactor may be used instead of two.



Hardware Description

Display On each Micro-Speed MV® you will find a display. The display will show rOFF or cOFF when not driving the motor.

rOFF means the drive is configured for horizontal motion, i.e. bridge or trolley.

cOFF means the drive is configured for hoisting.

When the drive is running, the display will indicate the speed (Hz) at which the motor is being driven.

The display is also used when a problem arises. To protect itself the drive shuts down -- this is called a fault -- the letter “F” will be shown on the display, followed by a number. This is a code which can be looked up in this manual to determine why the drive faulted (See Fault Codes).

Programming Buttons On each Micro-Speed MV® you will find three buttons marked Scroll (Load), Increase, And Decrease. These buttons are used to program the drive and to access diagnostic features.

Bus Charge Lamp This lamp warns that drive is still charged. Before servicing, disconnect power and wait at least 5 minutes. If the red charge lamp is still on after 5 minutes, wait until it is off. The red charge lamp must be off before proceeding further. It is necessary to follow these precautions because dangerous electrical energy will remain in the unit even after power is disconnected.

Control Terminal Wiring This chapter demonstrates typical control wiring schemes broken down into function.

Simple FWD and REV terminal wiring Use FWD=UP and REV=DOWN for hoisting applications.

The COM is the common terminal for the FWD, REV, S2-S5 and the AX1-AX4 terminals. COM should be connected directly to the X2 (common) of the 115 VAC control transformer.



Wiring Two Step Pendant

Use FWD=UP and REV=DOWN for hoisting applications.

The drive can be programmed to use a two speed button in at least two ways. The first way is to have each step command a predetermined speed to attain a low speed and a high speed. The second way is two speed infinitely variable mode. This works as follows:

The drive holds the speed it is currently running at if either the forward or reverse signal is present without any speed inputs being activated. The speed will not be held fixed if the forward or reverse signal present requires the motor to reverse its direction. In this case the motor will reverse its direction first. Also, the speed will not be held fixed below the low speed setting programmed in A12 (C21), it will first ramp up to A12 (C21) before holding the speed steady.

The drive accelerates or decelerates toward the appropriate programmed speed if any of the speed inputs S2, S3, S4, or S5 are activated along with either the forward or reverse signal.

Note: the speeds associated with S2-S5 may be turned off by setting their speed parameters C22-C25 to OFF. This may be useful when using these terminals for other purposes such as page swapping.

Pushing the pendant button down to step #1 would initially cause the drive to go into low speed A12 (C21). Pressing the button further, to step #2 would cause the drive to accelerate to high speed A16 (C25). If before the drive reaches high speed the button was shifted back to step #1, the drive would stop accelerating and hold that speed.



Wiring Three Step Pendant


The drive can be programmed to use a three speed button in at least two ways. The first way is to have each step command a predetermined speed to attain a low speed, a middle speed, and a high speed. The second way is three speed infinitely variable mode. This works as follows:

The drive accelerates or decelerates toward the low speed setting A12 (C21) if either the forward or reverse signal is present without any speed inputs being activated.

The drive holds the speed it is currently running at if the second step is activated and not step 3. The speed will not be held fixed if the forward or reverse signal requires the motor to reverse its direction. In this case the motor will reverse its direction first. Also, the speed will not be held fixed below the low speed setting programmed in A12 (C21), it will first ramp up to A12 (C21) before holding the speed steady.

The drive accelerates or decelerates toward the appropriate programmed speed if any of the speed inputs S3, S4, or S5 are activated along with either the forward or reverse signal.


Pushing the pendant button to step #1 would cause the drive to go into low speed A12 (C21). Pressing the button further to step #2 would cause the drive to hold its speed fixed. Pressing the button down to step #3 would cause the drive to accelerate to high speed A16 (C25). If before the drive reaches high speed the button was shifted back to step #2, the drive would stop accelerating and hold the speed at its current level.



Wiring Five Step Pendant


In this mode, the Micro-Speed MV® will:

Accelerate or decelerate toward the low speed setting C21 (C21 may be accessed through A12 in the A menu) if either the forward or reverse signal is present without any speed inputs being activated.

Accelerate or decelerate toward the appropriate programmed speed if any of the speed inputs S2, S3, S4, or S5 are activated along with either the forward or reverse signal.


Pushing the pendant button down to step #1 would cause the drive to go into low speed. Pressing the button further to step #2 would cause the drive to go into second speed. Pressing the button down to step #3, step #4, and step #5 would cause the drive to go into speeds 3, 4, and 5 respectively. In this mode, the five speeds would be programmed in A12(low speed), A13, A14, A15, and A16 (high speed).



Controlling a Mechanical Brake Typical brakes found on hoists and bridge trolleys, when energized, allow the motor to turn. When power is removed, the motor is stopped. If a mechanical brake is used it should be controlled by the Micro-Speed MV® through a brake contactor. The brake control terminals B1 and B2 are able to switch any DC voltage up to 24 V (1/4A.), and AC voltage up to 230 V (1/2A.). Below is an example of hoist brake wiring using the required two brake contactors.

Note: If running a bridge or trolley, only one brake contactor is required.



Motor overload input OL COM is the common terminal for the S2-S5, AX1-AX4 and the FWD and REV terminals. COM must be connected directly to the X2 (common) of the 115 VAC control transformer.

OL is the motor overload input. OL is to be connected to the COM terminal through an external normally closed overload contact.

When the external overload trips and a FWD or REV signal is present, the drive will stop immediately, put on the brake, and enter FAULT MODE where the fault code “F13” will be displayed. It will remain displayed until the drive is reset or turned off.

The trip level of the overload should be 125% of the motor FLA.



Analog Inputs The analog input terminals can accept an analog signal to control the speed of the motor.

Simple Analog Wiring Below is an example of a wiring scheme using a potentiometer that controls the speed of the motor.

Analog Terminal Description

Terminal Description

CGND Chassis ground. This terminal is connected to the drive chassis. The shield of a shielded cable may be connected here.

A0V This terminal is the common terminal for both inputs I1 and I2 and the ten volt power supply +10V.

I1 Analog input 1, switch settable for 0-5V, 0-10V, or 20ma control.

I2 Analog input 2, switch settable for 0-5V, 0-10V, or 20ma control.

+10V User +10V analog power supply.

Simple Analog input Programming Set Operation Mode parameter A9 (same as C20) to 3. When a Forward or Reverse input is active and there is no other speed input (S2-S5) then the drive will ramp to and run at the speed determined by the analog input I1.

Analog max output for terminal I1 (program parameter C31) determines the maximum motor speed.

Analog min output for terminal I1 (program parameter C32) determines the minimum motor speed.



Dip Switch Settings for Analog inputs I1 and I2 The I1 and I2 analog input terminals must be set for the type of signal you are using. This is done by changing the analog dip switches that are located just above the analog terminal strip. To change the setting, flip the appropriate switches for the setting corresponding to the signal you are using. See the Analog Dip Switch picture and table below.

Analog input I1 Dip Switch settings

SW1 Position SW2 Position Input Range

User Relays

User Relay 1 corresponds to terminal R1, R2, R3 and User Relay 2 corresponds to terminal R4, R5, R6.

User Relay Operation in Normal Mode

Normal mode is the state of the drive after it powers up and has not entered fault mode.

Once the Micro-Speed MV® is in normal mode, relay operation is governed by the C90-C95 parameters, C90-C92 correspond to Relay 1, and C93-C95 correspond to Relay 2. These parameters choose the relay operation mode, and time delays to relay activation and deactivation.

User relay operation parameters in normal mode

Parameter Parameter name Description

C90 Relay 1 operation mode Determines the conditions triggering relay 1 activation.

C93 Relay 2 operation mode Determines the conditions triggering relay 2 activation.

User Relay Operation for End of Run Brake Test Func tion

Parameter CL12 activates the End of Run Brake Test Function and also determines which user relay to use to signal its associated alarm. The assigned relay will then be unavailable for any other duty in normal mode.

User relay operation parameters for End of Run Brake Test


CL12 End of Run Brake Test Mode Determines if the Brake is checked at the end of a run and which user relay to signal its associated alarm.



User Relays In Fault Mode

When in fault mode the User Relay Functions are governed by CL32 for Relay 1 and CL33 for Relay 2.

User relay Fault mode operation


CL32 Fault mode Operation of Relay 1 Determines the state of Relay 1 in Fault mode CL33 Fault mode Operation of Relay 2 Determines the state of Relay 2 in Fault mode



Using Hoists in Tandem To set two hoists to work in tandem perform the following steps:

1. Interlock the drives by applying the wiring displayed below.



2. On each drive, set Relay 2 Mode (C93) to activate when the drive is ready or running (set C93 to 1). With this setting, the Relay will go off if a fault is recognized or if a programming menu is entered.

3. On each drive, set a Trip Mode (C50 or C52) to trip when AX1 is not activated and the unit is running (set C50 or C52 to 16).

4. On a hoist, there exists a delay between the moment that a forward or reverse command is applied, and the actual motion of the motor. This delay time will vary based on the type of motor and whether the Begin of Run Brake Test (CL14) is on. When running hoists in tandem, it is important that this delay time be synchronized between the two drives.

To synchronize the delay times, go to the Calculated Motion Delay Time (CL15) parameter. This read only value shows the amount of time it takes for the motor to move after a forward or reverse signal is applied. If these two values do not match you can extend the delay of the shorter time with the Enforced Minimum Motion Delay Time (CL16) parameter.

The CL16 parameter sets the lower limit of the delay between a forward or reverse signal and motor motion. Thus if one drive has a shorter delay time than the other, the CL16 parameter of the drive with the short delay can be increased to synchronize with the drive with the longer delay time.

Example:

Drive A has a Calculated Motion Delay Time (CL15) of .60.

Drive B has a Calculated Motion Delay Time (CL15) of .87.

To synchronize these drives we would increase the Enforced Minimum Motion Delay Time (CL16) of Drive A to .87 (CL15 of Drive B).

Note: In the wiring diagram and description we chose to use Relay 2 and Auxiliary terminal 1. You can choose Relay 1 or any of the other Auxiliary terminals instead. If you chose to do so, make sure the Relay Mode parameter that is set corresponds to the Relay used in the wiring to interlock the drives (Relay 1 corresponds to C90 and Relay 2 corresponds to C93). Also, make sure that the Trip Mode condition chosen corresponds to the Auxiliary terminal used in the wiring.



Verify Control Wiring

Verify Input Terminals FWD, REV, S2, S3, S4, S5, AX 1, AX2

Apply power to the Micro-Speed MV®.

Press and hold the scroll button, until the "E" appears, then release the scroll button.

Continually tap the scroll button until "E8.0" is displayed and wait.

The display should look similar to below. Each vertical line represents the on or off condition of a control input terminal. The terminal represented is labeled right below that vertical line. If the line is in the down position, that terminal is off (not energized). If the line is in the up position, that terminal is energized.

Press the pendant buttons while watching the display. If wired properly the corresponding red line will jump up. Check any of these inputs you plan to use by energizing and de-energizing the input and watching the corresponding display element for changes.

*Important note: For hoist applications, wire the FWD terminal for up and the REV terminal for down.

When finished press and hold the scroll button until "cOFF" or "rOFF" is displayed.

E8.0 diagnostic



Verify Input Terminals AX3, AX4 Repeat the procedure above, except press and release the scroll button until "E8.1" is displayed and wait. The two segments appearing will correspond to AX3 and AX4.

Verify Analog Inputs I1, I2

To check I1, repeat the procedure above, except press and release the scroll button until "E7.0" is displayed. The value of E7.0 should range from 0 to 100. Vary the input signal on I1 and check if the value displayed changes correctly with the varying signal.

To check I2, repeat the procedure above, except press and release the scroll button until "E7.1" is displayed.



Fusing Each Micro-Speed MV® should be individually fused. Use time delay fuses. Fusing for 480 VAC mains must use a voltage rating of 500 VAC or higher. Fusing for 230 VAC mains must use a voltage rating of 250 VAC or higher. The midget size fuses are easier to use on panels. Other crosses to the suggested fuses below may be utilized....

Brake Resistors

The Micro-Speed MV® requires external braking resistors. The required size of these resistors depends on the application, the motor's horsepower, and the motor's voltage. Purchase Power Electronics regeneration resistor products for best reliability.

Mount brake resistors in safe enclosure with adequate ventilation

The resistors can become extremely hot and have bare high voltage connections warranting placement in a touch-safe enclosure away from flammable material. The resistors will remain electrically hot for several minutes after the power has been disconnected. Also, the possibility of the resistor melting is present and requires the enclosure to prevent any molten material from causing injury or damage.



Programming the Micro-Speed The Micro-Speed MV® has parameters that can be programmed to tailor the drive's operation to the needs of the user. These parameters come in 5 menus: A, C, E, CL, and U. Below is the following procedure for accessing parameters in each menu.

Changing Parameters

1. Make sure the Micro-Speed MV® is on but not driving a motor and the display reads "rOFF" or "cOFF".

To enter a certain menu, hold down the Scroll button until that menu appears on the display. The order of progression that the menus take is A, E, C, CL, U.

The example that follows on the next few pages shows in detail how to access parameters in a menu. The C menu is shown as the example because it contains a lock parameter as the first parameter (C0). The CL and U menus also have this lock parameter (CL0 and U0), while the A and E menus do not. Besides the initial lock parameter, navigation methods are identical between menus.

Initial Display



Press the Scroll button on the cover of the Micro-Speed MV®. Hold this button down until C appears in the display and then release the button. The label C0 will appear on the display and 1 second later the value that C0 has will be displayed. Press the Increase button until the code the MAIN UNLOCK CODE (found on the last page of this manual) is showing. Press the Decrease button if you pass the value. By putting the MAIN UNLOCK CODE into C0, the C menu is unlocked allowing the user to change any of its parameters. If the MAIN UNLOCK CODE is not entered into C0, the C menu will be locked, and you will only be able to read the values of its parameters.

Holding down the Scroll button will run

Through the menus, A, C, E, CL, and U

Releasing the Scroll button on the desired

menu will bring up the menu’s first parameter label.

After one second of displaying the parameter

label, the parameter’s value will be displayed.

In the case of parameter C0, 369 must be input in order to unlock the rest of the C

menu.

Gang-Set ® Programming The Micro-Speed MV® contains 4 pre-set Gang-Set® programs, labeled from Ph05 through Ph08 for the hoist version of the Micro-Speed MV®. For the bridge or trolley version, the 4 pre-set Gang-Set® programs are labeled from Pb01 through Pb04. Each Gang-Set® program is actually just a list of “A” values which are factory chosen. When the Micro-Speed MV® is Gang-Set®, each “A” parameter is reprogrammed to a new factory chosen value. The Gang-Set® procedure is a simple and quick way to get the Micro-Speed MV® up and running. However since each “A” parameter is reprogrammed every time a Gang-Set® is initiated, all previous custom adjustments to individual “A” parameters will be lost. Therefore, all fine-tuning of individual “A” parameters must be done after Gang-setting and not before.

Loading the Gang-Set®:

Press and hold all three buttons simultaneously until “Ph 0” (“Pb 0“ for the bridge or trolley version) appears in the display and then release the buttons. This should take about 5 seconds.

Use the Increase and Decrease buttons to choose the desired program*.

Press the Scroll button for about 1 second to load the Gang-Set®. If a program other than “Ph 0” (“Pb 0”) is selected. The screen should briefly display “LOAD”.

Motor Tuning for Micro-Speed MV ®

This section provides detailed instructions concerning motor tuning. The motor may be tuned in or out of the equipment it powers. The following procedure will work in any situation where, once the motor is up to speed, the motor's speed will not change greatly if it loses torque for about ½ second, such as an unloaded hoist, bridge, or trolley.

The following description assumes a hoist. The bridge and trolley situations are similar.

Motor may be tuned in a hoist or on a bench. If in a hoist, make sure the hoist is UNLOADED during all tuning procedures. Also make sure that the FWD terminal corresponds to up, and the REV terminal corresponds to down.

The Micro-Speed MV® tuning process consists of four parts:

Tuning Part 1: Data Entry of Motor Nameplate Information Tuning Part 2: Encoder Verification and Test Run Tuning Part 3: Stationary Tune Tuning Part 4: Motion Tune.



Tuning Part 1: Data Entry of Motor Nameplate Inform ation 1. Ensure that hook is all the way down and no load is attached. 2. Access the U menu on the display and enter in the MAIN UNLOCK CODE (found on last

page of manual) for the parameter U0. This unlocks the U menu and allows users to change parameters.

3. Scroll to U20 and enter in all of the motor nameplate data for parameters U20 through U24. Also make sure U25 is OFF.

Parameter Label Parameter Name Paramet er Info

U20 Nameplate motor VAC Settable range = 100-660VAC

Typical values are 208, 220, 230, 240, 384, 415, 440, 480, 575

U21 Nameplate motor Hz Possible settings 50, 60Hz U22 Nameplate motor FLA (full load

amps) Read from nameplate

U23 Nameplate motor kw Read from nameplate, if only horse power given, enter 0.75 x (horse power)

U24 Nameplate Synchronous RPM Selection range is dependent on motor Hz chosen in U21

60 Hz Motor: 3600, 1800, 1200, 900 RPM

50 Hz Motor: 3000, 1500, 1000, 750 RPM



Tuning Part 2: Encoder Verification and Test Run

After the data is entered into U20-U25, the encoder and motor should be checked before proceeding to the actual auto-tuning. U40 through U49 are control parameters that are used to evaluate the drive, motor and attached encoder through a test run. During this test run, the motor is run in a standard V/Hz fashion. U40-U47 determined the running characteristics of the drive during this test run such as voltage boost, acceleration, ramp down cutoff speed, etc. The factory settings for these parameters will work in most cases. U48 determines the diagnostic quantity displayed during the test run. U49 initiates the test run.

Do the following:

1. Ensure that no load is attached, because the encoder is not being used in any safety capacity during a test run.

2. Scroll to U48 and enter 1. U48 controls what is shown on the display during the test run. Entering 1 will display the ratio of the speed determined from the encoder signal to the speed the drive is powering the motor to run.

3. Scroll to U49 enter the Main Unlock Code (found on last page of manual) and tap the scroll button. This starts a 5 minute timer during which you will be able to run the motor through a pendant station connected to the FWD and REV terminals.

For bench testing, the user may enter (the Main Unlock Code + 100) into U49 instead of the Main Unlock Code. This will allow the motor to be run by pushing the increase and decrease buttons as a substitute for the pendant.

4. Run the motor in the forward or reverse direction up to full speed. If the number displayed is 1.00 the encoder appears to be working so commence to Tuning Part 3: Stationary Tune.

5. If the number displayed is not 1.00 proceed with the following diagnostic steps: a. If the the display reads negative -1.00 then the wiring of the encoder is reversed and

should be changed (switch the encoder wires between terminals A+ and A-). Start the test run again and check for 1.00 on the display.

b. A number below or above 1.00 could be a mistake in the entering of motor input data--number of encoder pulses(U30) or the motor synchronous speed(U24)) -- or a fault in the encoder. Recheck your input data from the Data Entry Phase.

c. A value of 0 indicates that either phase A or phase B or both phases are missing. To check phase A independently set U48 to 2 and run the test at U49 again. A value of 0 on the display during this new test run will indicate that phase A is missing.

To check phase B independently set U48 to 3 and run the test at U49 again. A value of 0 on the display during this new test run will indicate that phase B is missing.

d. A value slightly above 1.00 indicates noise coming from the encoder. e. A value slightly below 1.00 indicates missing pulses, the encoder may be damaged or

not aligned properly. f. Other values suggest a mixing of the phases, maybe A+ is wired into A+ correctly, but

B+ may be wired into A- incorrectly.

U49 Initiate Test Run 0-9999 Enter the MAIN UNLOCK CODE (found on last page of manual) and tap scroll button to initiate a 300 second (5 minute) test run using hand switch direction signals.

-or-

Enter the (MAIN UNLOCK CODE + 100) and tap scroll button to initiate a 300 second(5 minute) test run using increase and decrease display buttons to simulate forward and reverse signals.

Note: The keypad buttons will ignore safety circuits in the machinery such as hoist upper limit switches. It is recommended that the pendant (with safety circuits) is used for running the motor in this test. On horizontal travel applications, be very careful that the operator is not in a position in which they could be inadvertently knocked by the bridge or trolley through unplanned movement.



Tuning Part 3: Stationary Tune

Scroll to U50, Enter the MAIN UNLOCK CODE (found on last page of manual) and tap the scroll button once. The display will show a countdown of 5 seconds, after which the Micro-Speed MV® will begin a 3-minute Tuning stationary period. The motor will not move during this time, and the screen will display dc with circling tickers.

When this tuning is complete, the unit will tell you to run the next Tuning part by displaying “run” for 2 seconds and then “U51”. It is possible to exit the 3-minute tuning period before it completes by tapping the scroll button. Although exiting in such a manner is not harmful, tuning information will not be stored unless this tuning period is allowed to run to completion.



Tuning Part 4: Motion Tune 1. Ensure that no load is attached. The motor will turn during this test. 2. Proceed to parameter U51. “0” should be displayed. If a “P.C.” type is displayed on the

screen instead, read the flag variable (U53) description at the end of this section for instructions.

3. Enter the MAIN UNLOCK CODE found on last page of manual and tap the scroll button – or, if bench tuning, enter the (MAIN UNLOCK CODE + 100), and tap the scroll button allowing the user to run the motor using the increase and decrease buttons. The screen should display 00.99.

4. Raise the hoist by using either the up button on the hoist pendant station or the increment button on the drive. As the hoist is progressing in the up direction the drive will be checking the motor.

The keypad buttons will ignore safety circuits in the machinery such as hoist upper limit switches. It is recommended that the pendant (with safety circuits) is used for running the motor in this test. On horizontal travel applications, be very careful that the operator is not in a position in which they could be inadvertently knocked by the bridge or trolley through unplanned movement.

5. The Micro-Speed MV® will show which stage of the tuning test it is in by updating the first two digits of the initial 00.99 that is displayed. As the testing passes certain milestones the 00 will increment by 2, yielding 5 stages (00.99, 02.99, 04.99, 06.99, dONE).

If you are raising the hoist and begin to run out of rope length before the test status reaches dONE, you may stop the test and lower the hoist to give yourself more rope length before proceeding in the up direction again. To lower the hoist, use either the down button on the hoist pendant station or the decrement button on the drive. Doing so will not affect the tuning test, and the tuning test will pick up at the same stage it left off at. (Example: Say you stopped raising the hoist when the screen displayed 04.99. After you have lowered it to an appropriate level, when you proceed with raising it, the test will begin again with stage 04.99)

6. The tuning test in U51 is complete when dONE is shown on the display. If more than 5 minutes have elapsed since entering the U51 test mode, P.C.05 will be displayed on the screen, and you will be required to start the test over by re-entering the MAIN UNLOCK CODE or (MAIN UNLOCK CODE + 100) and tapping the scroll button.

7. You may exit the menu and run the hoist.



FLAG variable description

Parameter U53 is the Tuning FLAG variable. The purpose of this variable is to keep track of what phase the tuning procedure is in so that phases are not executed out of order, and so that the hoist is not run in regular mode if tuning is not complete. Although the value of the U53 parameter is available for the user change, the tuning procedure automatically adjusts this variable. Usually the user will not need to alter the Tuning FLAG directly. This parameter can have the following values:

U53 Tuning FLAG

Value Status

50 U53 is set to 50 by the Micro-Speed MV® when the Stationary Tune U50 begins. If U53 remains set to 50, the unit will display “P.C.50” upon exiting the U menu.

51 U53 is set to 51 upon completion of the Stationary Tune. If U53 remains set to 51, the unit will display “P.C.51” upon exiting the U menu.

0 U53 is set to 0 upon successful completion of the Motion Tune. The unit will only run in normal operation if U53 displays 0.

C40 Deceleration Mode

0-1 0

0 Normal Mode

When decelerating between speeds C41 is used.

When decelerating to stop C42 is used.

When decelerating while Reverse Plugging C43 is used.

The drive will not allow the deceleration times of Deceleration to Stop (C42) or Deceleration When Reverse Plugging(C43) to be longer than the Deceleration 1(C41) deceleration time. If C42 or C43 are set to be longer than C41 then the drive will use the value of C41 for C42 or C43.

Additionally, the drive will not allow Deceleration When Reverse Plugging (C43) to be longer than Deceleration to stop (C42). If C43 is set to be longer than Deceleration to C42, the drive will use the value for C42 for C43.

1 Wound Rotor

Simulation

If you change the direction of the motor (Reverse Plugging mode), the motor will decelerate at a rate in between Deceleration to Stop (C42) and Deceleration When Reverse Plugging (C43). The rate between these two boundaries will be determined by the selected speed input (S2-S5). The higher the speed input selected, the more the deceleration mode will reflect the C43 value.

C41 Deceleration 1 0.1-60.0 Sec. Determines the default deceleration rate at which the drive decelerates between speeds.

Page Swapping Page swapping is the means the Micro-Speed MV® uses to vary it's parameters as the situation demands.

Basically, the Micro-Speed MV® contains 9 additional menus labeled P1 through P9. We refer to these menus as page menus, or as P menus, or simply as pages. Each page is similar to the original C menu, but contains only the changes the user wants to make to the C menu rather than the entire menu. The changes these pages contain can be swapped in and out “on the fly”, to effectively alter the C menu as the user desires.

The page swapping feature allows the user to program each page to alter multiple C menu values, and determine when and under what conditions they are switched in and out.

The page menus will not appear as selectable menus until their page trigger source parameters CL51-CL59 are activated. CL51 activates P1, CL52 activates P2, etc.... Each CL5x parameter determines the source that triggers a page swap, and have a range of OFF, 0-9999. By default they are OFF causing no page menus to appear. Set to any other value, the corresponding page menu will appear as a normal menu.

Simple Page Swapping

A simple form of page swapping involves swapping a page upon the condition of a single external input (AX1, AX2, AX3, AX4, S2, S3, S4, or S5) and also upon whether the motor is going forward (UP) or reverse (DOWN).

Here is how it works.

1. Unlock the CL menu. Scroll to the CL menu and unlock it (enter the Main Unlock Code into CL0).

2. Activate the desired page menu. Choose a P menu to activate by scrolling to one of the page trigger source parameters (CL51-CL59).

The table on the following page describes a TRUE or FALSE expression for each possible value between 0 and 99. (Note, the actual range of CL51-CL59 is up to 9999, we will discuss this extended range later.) Select the value between 0 and 99 that corresponds to the input condition you desire to trigger the page swap. The page will be swapped in when the expression is TRUE and swapped out when the expression is FALSE.

Enter the selected value. The P menu is now active and will show up as a normal menu.

3. Edit the P menu. Now leave the CL menu. Scroll through the menus again to find the new P menu. It will appear after the C menu but before the CL menu. Enter this menu and unlock it and proceed to change any necessary parameters. The changes made to this menu will be substituted for the original C menu parameters when the page is swapped in.

By default, all parameters in a P menu are set for no change. A parameter representing no change is represented by two dashes, “ -- “. An unchanged parameter will cause no change when the page is swapped in.

Upon entering a P menu, it is important to note that all of the parameter labels within it have C menu labels. However, when you tap the scroll button as if to edit a parameter, the screen will flash the label of the P menu currently being edited. This ensures that improper changes are not being made to the C menu or a different P menu.

90-99 FALSE (reserved)

Notes 1. AX1 is TRUE when input terminal AX1 is activated, it is FALSE when terminal is not

activated. 2. !AX1 is FALSE when input terminal AX1 is activated, it is TRUE when terminal is not

activated. 3. Do not use any of the reserved values, use value=25 if you need a FALSE. 4. 30-55 is the same as 0-25 except it will only be TRUE in the Forward (UP) direction. 5. 60-85 is the same as 0-25 except it will only be TRUE in the Reverse (DOWN) direction.

Example 1: Suppose the acceleration time C11 is 4.0 seconds and we want to change it to 2.6 seconds when terminal AX3 is activated.

ANSWER: Use page P1 to handle this task. Unlock the CL menu, scroll up to CL51 and enter 3. This will cause P1 to be swapped in when AX3 is activated. Leave the CL menu and scroll to the P1 menu, unlock it, scroll up to P1_C11 and enter 2.6 . Leave the menu and run the drive. P1_C11 will now be swapped in for C11 when AX3 is activated.



Example 2: Suppose the acceleration time C11 is 4.0 seconds and we want to change it to 2.6 seconds when terminal AX3 is activated but only in the reverse (DOWN) direction.

ANSWER: same as example 1 but enter 63 into CL51 instead of 3.

Multiple Page Swaps It is possible to swap in two or more pages at the same time. If they each contain changes for different parameters, there will not be any interference. If they both try to change the same parameter, the higher numbered page wins. For example, if both P1 and P2 are swapped in and P1 has P1_C11=5.5 and P2 has P2_C11=4.4, then the final result for the acceleration time will be 4.4 since 2 is greater than 1.

It is extremely useful that the higher numbered page wins and a key property of our page swapping feature.

Clearing Page Menus All page menus, P1-P9, will be erased by entering the Main Unlock Code into CL60 and tapping the scroll button. Note that the CL menu must be unlocked first.

To clear all entries in an individual Px menu, go to parameter CL6x and enter the Main Unlock Code and tap the scroll button. For example, CL61 erases P1, CL62 erases P2, etc.

Full Page Swap (Power Swap) The Micro-Speed MV® has 9 internal page timers, T1-T9, each associated with a page menu, P1-P9.

Each page menu's timer can be used to trigger its swap.

The output of it’s timer can also be combined with an external input or a motor direction to trigger the swap. The specific combination is determined by CL5x.

As we have seen, values of CL5x between 0 and 99 will cause the page swap to be triggered only by an external input or a motor direction. Values above 99 incorporate the timer output.

For values above 99, the Lower Two Digits still determine a dependence on an external input or a motor direction as per the table CL51-CL59 Lower Two Digits. This dependence is then combined with the timer output as shown by the following table to ultimately control the swap.

TIP: To get just the timer triggering the page Px, set CL5x to 100 .

Suppose CL53=100.

The upper digit of CL53 is 1, so from the table CL51-CL59 Upper Two Digits the final governing expression is (LTD3 and T3).

The Lower Two Digits of CL53 are 00. From the table CL51-CL59 Lower Two Digits, the 0 entry is TRUE, so LTD3=TRUE.

The final governing expression is (LTD3 and T3) = (TRUE and T3) = T3

Hence CL53=100 makes P3 swap conditioned entirely on the state of timer T3.

Example 4:

User wants P4 to swap in when T4 is off (FALSE), and only in the forward (UP) direction.

Answer: Choose the upper digits of CL54 to be 2, this gives the “and” function and the !T4 function as per the table CL51-CL59 Upper Two Digits . Further, choose the Lower Two Digits to be 30 to get the forward piece as per the table CL51-CL59 Lower Two Digits. Hence choose CL54=230.

Page Timers T1-T9 Much of the power in page swapping comes from the 9 internal page timers. Not just because they are timers, but because there are so many ways to control their operation. The following is a diagram of the page swapping logic including the page timers and their control logic.

The page swap control diagram shows that timer Tx feeds the page trigger source block. Menu item C2x8 determines its on delay time and C2x9 determines its off delay time. For instance, if the combination term COMBx gating the timer becomes TRUE, then the timer will delay the time stored in C2x8 before it sets its output to ON (TRUE). Likewise, if COMBx becomes False then the timer will delay the time stored in C2x9 before it sets its output to OFF (FALSE). C2x8 and C2x9 are set to 0.0 seconds by default. Upon power up, the timer starts in the OFF condition.



The combination term that gates the timer is simply a logical combination of the three single terms Ax, Bx, and Dx feeding its block. The specific logical combination of these single terms that gates the timer is governed by menu item C2x0.

Each single term Ax, Bx, or Dx, that feed the combination block can be set to reflect practically any condition present in the drive. Menu items C2x1 for Ax, C2x2 for Bx, or C2x3 for Dx are to be programmed with a specific drive condition from a long list of conditions. Some conditions in this list include the state of terminal inputs AX1,AX2,AX3,AX4,S2,S3,S4, and S5, state of the Zip feature, whether the drive is reverse-plugged, motor is going forward, reverse, zero speed, accelerating, decelerating, constant speed, etc. Also listed is whether any page P1-P9 is swapped in, state of any timer T1-T9, and the state on any combination term.

Other conditions in this list are that of user defined comparisons. Menu items C180-C209 control 10 comparison blocks. Each comparison block can compare the speed, current, torque, analog input1, or analog input 2 with a user defined value or with one or both of the analog input signals.

Finally, the menu items we discussed belonging to the C menu -- C180-C209 for comparisons, C2x0 combination term, C2x1, C2x2, C2x3 single terms, and the timer delays, C2x8 and C2x9 – are all subject to change when a page is swapped in or out because they belong to the C menu.

Let’s demonstrate the power of page swapping with a few easy examples.

Example: User wants the acceleration time C11 to change to 5.5 seconds, with a time delay of 1.3 seconds after terminal AX1 is activated.

Solution: Use page P6 to solve this example. Set CL56 =100 so that P6 will be swapped in when timer T6 is turned on. Set the ON delay of timer T6 to 1.3 seconds, that is C268=1.3. Set the page 6 combination term, COMB6, to just look at the single term A6, that is C260=2. Set the single term A6 to look at terminal AX1, that is C261=11. And finally, enter the P6 menu and change P6_C11 item to 5.5 seconds.

Example: Same as above but the user also wants the acceleration changed only in the reverse (DOWN) direction.

Solution 1: same as previous example but set CL56 to 160, then the paged will be swapped in only in the reverse direction when the timer goes on.

Solution 2: same as previous example but change set the page 6 combination term, COMB6, to be the logical AND of single terms A6 and B6, that is C260=10 . Finally set the B6 term to check for reverse direction, that is 131.

Example: Make a slack load detection feature for a hoist using just one page. A slack load occurs when a hoist with a fixed minimum load – like a scrap yard hoist with a magnet – lowers its load to the ground. The user would want the drive to detect this condition and stop the hoist from going down farther in order to keep the hoist rope from unwinding from the hoist drum.

Solution: Use page P4 to solve this, set CL54=100.

Now set the block 2 comparison mode, C186, to monitor the torque and become TRUE when the torque falls below the block 2 comparison value, C187. Set the block 2 comparison mode to 2120, that is C186=2120. Set the block 2 comparison value to 12.0% of full motor torque, that is C187=12.0. There are many comparison modes that use torque, we chose the one C186=2120 that filters the torque signal and subtracts off the inertia setting-- C179 – to compensate for acceleration and deceleration torques. Now set the inertia in C179 to 0.4 seconds. The user may adjust this parameter later.

Next program single term A4 to include comparison 2, set C241=42, and program single term B4 to monitor the reverse direction, set C242=131. Program the page 4 combination term to look at the logical AND of A4 and B4, set C240=10. Timer T4 will now be gated when the torque drops below 12% while moving in the down direction. Its good practice to put in a short ON delay into timer T4 to insure against spurious events, so set C248=0.5 seconds. Page P4 will now be swapped in when the torque drops below 12.0% for 0.5 seconds while moving in the down direction.



Now go to the P4 menu and set P4_C29 to 0.0. This will apply a maximum speed limit of 0.0 in the down direction when page P4 is swapped in, preventing the hoist from uncoiling further.

We also need to reset our slack load detection feature, that is to swap out page P4, when the slack load condition is removed. We do this by altering more parameters in page P4 so that the timer will be gated off when then torque becomes greater than 15% while moving in the forward (UP) direction.

This is simply done with:

P4_C186=3120, change comparison mode 2 to check if torque is greater than compare value.

P4_C187=15%, change comparison value 2 to 15% of full motor torque for hysteresis in checking the torque.

P4_C242=130, change single term B4 to detect forward (UP) direction.

P4_240=9, change COMB4 from (A4 AND B4) to !(A4 AND B4), thus inverting the timer T4 gate so that it will go OFF (false) when the reset conditions are met.

Again, it is good practice to put some OFF delay time into T4 to guard against spurious events. This could be done by either setting C249 or P4_C249 to 0.5 seconds. We suggest making the change in the original C menu, so set C249=0.5.



Combination Term Description C2x0 for x=1 to 9 For combination terms that use at most just the A and B single terms, use the following chart to select a mode value. All possible expressions using just A and B are represented in this chart. The expression 0 is the same as FALSE, and 1 is the same as TRUE. The “!” is the “NOT” operator and xor is the exclusive or operator.

For combination terms that use all single terms A, B, and D, use the chart on the following two pages to select a mode value. The chart gives an expression using just A and B for each possible value of D, 0-1. So if the user has an expression using A, B, and D in mind, simply put a 1 in for D and record the resulting A and B expression, then put 0 in for D and record the resulting expression. Then match those expressions in the chart to find the proper mode. All possible expressions involving A, B, and D are contained in this chart.

Diagnosing Problems There are two key features in the Micro-Speed MV® that assist the user in diagnosing problems. The first is the displaying of fault codes when the drive trips out. The second consists of 11 diagnostic "E" memory locations that are accessible through the buttons and display on the front panel.

When a problem arises, such as excessive current draw, the drive will protect itself by shutting down and displaying a fault code. This action is called faulting out or tripping out. The fault code reveals information about the type of fault that occurred. By looking up the cause of the fault, one can gain information of how to solve the problem.

The 11 "E" memory locations are accessible in a manner similar to the "A" programming parameters except that they cannot be programmed. They either display diagnostic information or they perform a function when the increase or decrease buttons are pushed. With these 11 memory locations one can recall the last four faults codes that occurred, activate the user relay contacts individually, and read out the state of every input on the logic board.

At the end of this section, there is a trouble shooting guide for some common problems that occur. Following every fault code description, there is a listing of the possible causes and corrective measures that may be taken.

How the Micro-Speed MV ® responds to a Fault When a fault occurs, five events will happen:

1. The Micro-Speed MV® will shut down. 2. The brake outputs, B1 and B2, will open. 3. A user relay will switch if programmed to switch under a fault condition. 4. The fault error code will be displayed. 5. The fault error code will be stored at E1.

Resetting after a fault The method by which the Micro-Speed MV® may be reset is determined by programming parameter CL10. Usually, the Micro-Speed MV® is programmed to reset when the button on the pendant station is toggled (press-release). It may also be programmed to reset by activating an auxiliary terminal. No matter what CL10 is programmed for, resetting of the Micro-Speed MV® can always be accomplished by turning off and then turning on the line power feeding the drive.

Remembering a fault The Micro-Speed MV® will remember the last four different faults. They are stored in the diagnostics memory locations E1, E2, E3, E4. Memory location E1 contains the most recent fault code. These locations could help diagnosis a problem - including motor and other mechanical conditions. These memory locations can be cleared through memory location E11, in which case they will display code F0.

Interpreting fault codes When a fault occurs one of the codes on the next page will be displayed, and action should be taken to correct the cause. The table on the next page will explain each fault and give possible causes. If the appropriate changes do not relieve the problem then please contact the factory for further assistance.



Fault Codes Label Type Description

F0 No Fault This value will be seen when checking the stored fault codes, if no fault was stored, or after the memory was cleared.

F1 Current Trip Current has risen to over 300% of rated output current.

The current trip is the most common fault and has many causes. Observing how the Micro-Speed MV® and the machine it is driving act at the moment the fault occurs will help the user in diagnosing the cause of the fault. If the drive trips out immediately when it receives a forward or reverse signal, then the following could be the causes:

1. Output semiconductor is shorted. An output semiconductor short can be tested for by disconnecting the motor leads from the drive and running the drive at some speed. The drive will trip out with no motor attached if there is an output short.

Solution: Send drive back to factory for repair. 2. Motor problems. Specifically, a short in the motor, motor leads shorted together,

motor leads shorted to ground, the motor windings are wired wrong, the motor is the wrong voltage, the motor may be single phasing, or the current rating of the motor is too large for the drive. Also some motors have internal brakes that receive power from the three motor leads -- this type of motor should not be used with inverters unless the brake power leads can be brought out separately and powered from the line and not the drive.

Solution: Check motor and wiring, repair or replace if necessary. 3. Mechanical brake not operating properly.

Solution: Make sure that any mechanical brake that is used is releasing cleanly without any dragging. Some motors have internal brakes, make sure these are also operating.

4. The motor is slipping so excessively that torque is not efficiently produced.

Solution: If the fault occurs while the motor is accelerating, then increase the acceleration time A1.

Solution: If the fault occurs while the motor is decelerating, then we suggest first observing whether the trip occurs when decelerating between speed, decelerating to a stop, or decelerating during a reverse plug condition. The three deceleration parameters A4, A5, and A6 govern these three rates (respectively) and increasing the appropriate parameters may alleviate the problem. One could also set A5 and A6 to their maximum value and just increase A4 gradually to obtain a setting that will work.

Solution: In the case where the motor does not turn but the drive ramps up and then trips out, one should first check that any mechanical brake that is used is releasing cleanly, that there is no mechanical binding in the system, and that the motor is wired properly and not single phasing.

5. Mechanical binding.

Solution: Investigate source of binding and fix. 6. Sometimes electrical noise can be induced on the motor leads from other wires

that run along side them, such as brake leads. When the brake operates, the noise from the arcing in the brake contactor can trip out the drive. This failure can be ruled out if the drive does not fault out at the instant the brake contactor switches.

Solution: Run motor leads in a conduit separate from other leads. 7. Starting into a spinning motor.

Solution: Don’t start into a spinning motor. If the motor is spinning because the brake is setting slow, then use the dead time parameter to increase amount of time the brake has to set before the drive will start again.

8. A slow mechanical brake on a Hoist may not be able to stop the motor before the Micro-Speed MV® is signaled to begin powering the motor again. This



Label Type Description

effectively causes the Micro-Speed MV® to start into a spinning motor.

Solution: Increase the dead time parameter to increase amount of time the rotor has to lose its magnetic field. Usually 1.5 seconds is more than sufficient.

9. The load is too large.

Solution: Reduce load or increase motor and drive capacity. Over current trip during test run (U49).

No-load motor current may be higher than expected. Decrease the test voltage boost (U43).

F2 I2T TRIP I2T Current trip F3 Low Buss Voltage The voltage across the main buss capacitors has dropped below a preset level

while the drive is running. Could be fluctuating input power. F4 Low Buss Voltage The voltage across the main buss capacitors has dropped below a preset level.

This fault is a normal occurrence every time power is remove from the drive. This fault is not save in the diagnostic memory E1-E4 since the drive will not operate while displaying F4 as long as the low voltage condition persists. This also saves the memory E1-E4 for other more severe fault codes.

F5 Over Voltage Trip The voltage across the main buss capacitors has increased above a preset level, this may have been caused by the following:

1. Line voltage spikes too high. 2. Deceleration rate too high.

Solution: Increase the deceleration times in A4, A5, and A6. You may only need to increase the faster of these times to get drive to function properly. It is usually easier to start by increasing both A5 and A6 to their maximum setting of 30.0 seconds and then gradually increase A4 to get proper operation.

3. Drive has started into a spinning motor.

Solution: Make sure motor has stopped before the drive is allowed to power the motor.

4. The external braking resistor may be wired wrong, open, missing, or its resistance value may be too large.

Solution: The resistance of the braking resistor is considered too large if it more than 110% of the value listed in the BRAKING RESISTOR section of this manual. If this is the case, replace the resistor with one that agrees with this spec. Never use a resistor with fewer ohms than the spec. calls for.

If no braking resistor is used you will probably need to add one. See the BRAKING RESISTOR SECTION OF THIS MANUAL.

If the braking resistor is open, one must try to identify its cause. Follow the following steps:

a) Check that the resistor(s) are wired properly.

b) Check to see if anything could have touched one of the wires feeding the resistor to create a short. If you find this is the case we recommend that the drive be shipped back to the factory--even if it appears to function properly when a new resistor is put in--with a note describing what was found so that the transistor that powers the resistor can be replaced.

c) Check to see if the resistor had at least as many watts as the spec. calls for (see the BRAKING RESISTOR section). If not, replace the resistor with one that agrees with this spec. In rare instances, even the watt rating in our spec. will not be high enough (perhaps the duty cycle of the machine is very high). In this case, increase the watt rating. Call the factory for help if needed.

d) It is possible that the transistor in the drive that powers the resistor has shorted.



Label Type Description

To check this, detach the motor and run the drive at some speed and check the DC voltage across the open resistor (be careful here, as much as 800 volts may be present). There should be only a few volts present at most. If not, return the drive to the factory for repair.

Solution: Call factory for assistance. F9 CPU Error

F12 Hardware fault Solution: Return unit to factory for service. F13 Overload - External

F14 Output phase loss If a line to the motor is lost or fusing opened between motor and the drive.

Also, A loose encoder coupling can cause the VFD to over-compensate. This may cause the current to fall so low as to appear to be a lost phase.

Diagnostic “E” Variables The Micro-Speed MV® is equipped with several diagnostic features each of which is accessible by using the display and the three buttons on the front cover of the drive. These diagnostic features are associated with 11 "E" memory locations labeled E1 through E11.

To View or Operate a Diagnostic “E” Variable

1. Make sure the drive is on but not driving a motor and the display reads OFF. 2. Press and hold the scroll button. First an "A" will appear then in a few seconds an "E" will

appear. Release the scroll button when the "E" appears. The label E1 will appear on the display and 1 second later the contents stored in the E1 memory location will be displayed.

3. Poke the scroll button several times fairly quickly (less than 1 second between pokes) and watch the sequence of parameter labels E1, E2, E3,... appear on the display. Stop poking the scroll button when the label of the memory location you want to view appears on the display.

4. The memory location label will be displayed for about 1 second and then the memory contents will be displayed to be read by the user. A description of each diagnostic memory location is below.

5. To view or operate another diagnostic feature go back to step 3 and poke the scroll button until the label of the next "E" memory location you want appears and then continue on as before.

6. To finally leave this "E" diagnostic mode, press and hold the scroll button down until the display reads OFF. This will take about 5 seconds during which the current memory location label will be displayed.

Diagnostic Memory Location

Phase B count

Displays the quadrature count from the encoder minus 2X phase B count. Useful for finding missing pulses on phase B. F18 will show if Phase A circuit has no power. F19 will show if Phase B circuit has no power. The Increment or Decrement button resets the count.



Quick Use Parameters The “A” parameters listed are the most commonly used “C” parameters. These have been separately listed in the drive for quick easy access. Typically just adjustment of a few of these will be all that will be necessary for most applications. The “equivalent” C parameter, listed in the parenthesis, will accomplish the same adjustment and change the corresponding “A” parameter if modified from the C menu.


A1 (C11) Acceleration 1 0.1-60.0 Sec. Default acceleration rate between speeds

see C10 for alternate “modes” A4 (C41) Deceleration 1 0.1-60.0 Sec. Default deceleration rate between speeds
