Figure 1-1: System concept SINAMICS G120

1.1 Power Modules

The power modules of the SINAMICS G120, corresponding to the MICROMASTER MM440, are the PM240 power modules. As the MICROMASTER MM440 the power modules PM240 have

a 6 pulse rectifier with diodes a dc voltage link with electrolytic capacitors



Version: 1.0, Item ID: FAQ-01LUJQCY

an integrated chopper to control an external braking resistor a converter with IGBT’s to control the motor.

The PM240 Power Modules match in the output power, the output current, and the overload capacity to the power units of the MICROMASTER MM440. What has changed is the name of the duty cycles: the term VT (variable torque) is redefined in the SINAMICS G120 to the term LO (low overload), the term CT (constant torque) to the term HO (high overload)

Figure 1-2: Technical data of the Power Modules PM240



Figure 1-3: Overview of the Power Modules PM240

The Power Modules PM240 are currently being supplemented by additional voltage versions 1/3AC200V and are replaced in the power range 0.55 kW to 15kW (LO ) by the Power Module PM240-2. Significant advantages compared to the the Power Modules PM240 are

Temperature controlled fan in the power section Dimensions more compact than the PM240 More power available in the same frame size Double rating of the power (HO/LO) also for units FSA Integrated filter class A also for units FSA

Note Power Modules PM240-2 FSA with 3AC 400V can already be delivered and are listed in the catalogue D31N January 2013. Sales release for the Power Modules PM240-2 1/3AC200V FSA … FSC and 3AC400V FSB … FSC will be end of 12/2013, delivery release is planned to be two month later.

1.2 Control Units

1.2.1 Preferred Migration

For the migration of the MICROMASTER MM440 to the control units of the SINAMICS G120 the following standard possibilities are provided:

MM440 without communication module and without pulse encoder evaluation module control unit CU240E-2

MM440 with PROFIBUS communication module and without pulse encoder evaluation module control unit CU240E-2 DP

MM440 with CANopen communication module and without pulse encoder evaluation module control unit CU250S-2 CAN (further notes see chapter Fehler! Verweisquelle konnte nicht gefunden werden.)

MM440 without communication module and with pulse encoder evaluation module control unit CU250S-2

MM440 with PROFIBUS communication module and with pulse encoder evaluation module control unit CU250S-2 DP

MM440 with CANopen communication module and with pulse encoder evaluation module control unit CU250S-2 CAN

Figure 1-6: Migration MICROMASTER MM440 to the control units of the SINAMICS G120

The quantity structure of the control units CU240E -2 and CU250S - 2 on inputs and outputs is shown in the following table. Additionally there is a Control Unit CU240B-2, when the application copes with 4 digital inputs, 1 digital output, 1 analog input and 1 analog output. The control unit CU250S-2 offers the possibility to connect up to 2 encoders for speed and position detection.

Resolver and pulse encoder with HTL signal can be connected to the terminals.

1.2.3 Overview Terminals

The control units of the SINAMICS G120 are equipped with pluggable terminals. The terminal designation is identical to the designation of the MICROMASTER MM440.

Figure 1-10: Comparison of the arrangement of the terminals




The following table shows the differences between the terminal arrangement of the MICROMASTER MM440 and the control units CU240B-2/CU240E-2/CU250S-2.

Figure 1-11: Terminal arrangement of the MICROMASTER MM440 compared to CU240B/E-2 and CU250S-2

1.3 Operator Panel

1.3.1 Basic Operator Panel BOP

The operator panel BOP used together with the MICROMASTER MM440 complies with the operator panel BOP-2 of the SINAMICS G120. Opposite to the BOP of the MICROMASTER the BOP-2 offers a menu structure for parameterization, quick commissioning and display. Further Features: Language is English Display of up to two process values at the same time Series commissioning by copying of parameter lists Display of parameter term and parameter value at the same time Direct manual mode of the drive



BOP BOP-2

1.3.2 Advanced Operator Panel AOP

For the Advanced Operator Panel AOP there is no direct counterpart in the portfolio of the SINAMICS G120. Storage and copying of data sets is possible with the BOP-2 as well as the IOP. Additionally there is the possibility to store and copy data sets via a SD card, which is inserted in a slot in the control unit. For a comfortable operation and commissioning guided by wizards the intelligent operator panel IOP is available. IOP

Further features: Languages: German, English, French, Italian, Spain, Portuguese, Dutch,

Swedish, Russian, Czech, Polish, Turkish. In IOP with older firmware version than V1.4 language packages can be

uploaded Graphical display with status indication with free selectable dimensions Structured menus Diagnostic by clear text display with integrated help function Simple commissioning of standard applications by wizards

Note The remote control of up to 31 converters as with the AOP is not possible with the operator panel of the SINAMICS G120. The BOP-2 and the IOP offer only a RS232 interface for a point to point communication.

Note Neither the BOP-2 nor the IOP have an integrated real time clock and timer functions as the AOP. If these functions are essential, a control unit CU230P-2 must be installed, which is especially designed for applications in HVAC and Water/Wastewater.




1.3.3 Asian Advanced Operator Panel AAOP

Note The display of Chinese characters is neither possible with the BOP-2 nor the IOP due to a low resolution of the display.

1.3.4 Cyrillic Advanced Operator Panel CAOP

Note The display of Cyrillic characters is possible with the IOP and uploaded language package 2 (see ID 73159342)

Furthermore the functional limitations concerning the Advanced Operator Panel AOP (see chapter 1.3.2.) have to be considered

1.3.5 Manual Operation by BOP-2 / IOP

For the MICROMASTER MM440, the manual mode is realized by switching over command data sets. For the control units of the SINAMICS G120, switchover to the manual mode is realized using the manual button on the BOP-2 / IOP. When the manual mode is activated, the BOP-2 / IOP assumes master control, the parameterized/active command and set point sources are therefore decoupled.

Note Manual operation from the IOP / BOP-2 can be inhibited using parameter p0806. This inhibit can be permanent, or also selected via a digital input or a fieldbus signal.

Note Manual operation via BOP-2 / IOP is not continuously active; it must be reactivated after power on.

Note OFF functions by p0845 „OFF2 signal source 2“ and p0849 „OFF3 signal source 2“ are active also together with the master control by the BOP-2/IOP.

Note The operating elements of the BOP-2 / IOP cannot be used as BiCo sources for internal commands; the BOP control word r0019 of the MICROMASTER does not exist anymore.

1.4 Operating Software DRIVE MONITOR

Note Frequency converter SINAMICS G120 can only be parameterized, commissioned and monitored together with the operator software STARTER. The operating software DRIVE MONITOR is not supported by the SINAMICS G120.




1.5 Further Information

Further information for the migration of the MICROMASTER series towards the SINAMICS G120 family is available in the INTRANET. On the homepage MICROMASTER – Migration a program is available to convert order numbers of MICROMASTER into the actual order numbers of the necessary components of the SINAMICS G120. https://intranet.automation.siemens.com/mc-app/mm4converter/index.html

2 Parameterization



2 Parameterization A direct migration from projects with MICROMASTER MM440 to control units of the SINAMICS G120s is not possible as a result of the modified parameter structure.

Note The drive must be recommissioned using BOP-2, IOP or STARTER.

2.1 Quick commissioning

The functional scope of parameter p0010 "Drive commissioning filter" has been expanded.

Parameter Action P0010 0: Ready

1: Quick commissioning 2. Power unit commissioning 3. Motor commissioning 4: Encoder commissioning 5: Technological applications/units 11: Function modules 15: Data sets 17. Basic positioning commissioning 25: Closed-loop position control commissioning 29: Only internal Siemens 30: Parameter reset 95: Safety Integrated commissioning

Diagram 2-1: Versions of the quick commissioning

2.2 User-defined parameters

The "user-defined parameters" function with 20 freely-definable customer parameters has been replaced by the know-how protection function. The know-how protection is used, for example, so that a machine manufacturer can encrypt his configuration know-how and protect it against changes or copying. The know-how protection is available in the following versions:

Know-how protection without copy protection (possible with or without memory card)

Know-how protection with copy protection (possible only with Siemens memory card)

A password is required for the know-how protection. In case of active know-how protection, the STARTER dialog screens are locked. You can, however, read the values of the display parameters from the expert list. The values of the adjustment parameters are not displayed and cannot be changed. Actions listed below can be executed even when know-how protection is active:

Restoring factory settings Confirming messages

Displaying messages Displaying the alarm history Reading out diagnostic buffer Switching to the control panel (complete control panel functionality: Fetch

master control, all buttons and setting parameters) Upload (only parameters that are accessible even though know-how

protection is active) Actions listed below cannot be executed when know-how protection is active:

Download Export/Import Trace Function generator Measuring functions Automatic controller setting Stationary/rotating measurement Deleting the alarm history

2.3 Macro drive unit

The pre-assignment of Control unit terminals using macro parameter p0700 "Select command source", p1000 "Select frequency set point and combination parameter p0719" and "Select command and set point source" is replaced by the macro saved in parameter p0015.

jogging via DI3“ Default setting CU250S-2 CAN macro 22 „Fieldbus CANopen“

2.4 Switch Over 50/60Hz

Power modules of the SINAMICS G120 do not have a DIP switch to adjust the mains frequency. The selection during quick commissioning for motors according IEC standard and SI units, NEMA standard and US units, and NEMA standard and SI units is done exclusively by parameter p0100.

2.5 Expanded command/drive data sets

For the control units of the SINAMICS G120, up to 4 command data sets (CDS) and up to 4 drive data sets (DDS) are available. However, contrary to the CU240E and CU240S, these must first be enabled using parameter p0170 (CDS) or p0180 (DDS).

2 Parameterization


2.6 Selecting the motor type

Parameter p0300 "Select motor type" has been expanded by the function for certain motor types to read in the motor data via code numbers.

2.6.1 CU240B-2 and CU240E-2 Control Units

Parameter Action

p0300 0: No motor 1: Induction motor (the rotary) 2: Synchronous motor (rotary, permanent magnet) 10: 1LE1 standard induction motor 13: 1LG6 standard induction motor 17: 1LA7 standard induction motor 19: 1LA9 standard induction motor 204: 1LE4 synchronous motor

Diagram 2-3: Versions of connectable motors A motor can be selected from the motor parameter list using parameter p0300. When changing the code number (exception, to a value of zero), all motor parameters are preassigned from the parameter lists internally available.

Note Only code numbers of motors can be set, which correspond to the motor type selected in p0300.

2.6.2 CU250S-2 Control Unit

Parameter Action

p0300 0: No motor 1: Induction motor (the rotary) 2: Synchronous motor (rotary, permanent magnet) 10: 1LE1 standard induction motor series 13: 1LG6 standard induction motor series 17: 1LA7 standard induction motor series 19: 1LA9 standard induction motor series 100: 1LE1 standard induction motor 104: 1PH4 induction motor 107: 1PH7 induction motor 108: 1PH8 induction motor

Diagram 2-4: Versions of connectable motors

A motor can be selected from the motor parameter list using parameter p0300. When changing the code number (exception, to a value of zero), all motor parameters are preassigned from the parameter lists internally available.

Note Only code numbers of motors can be set, which correspond to the motor type selected in p0300.

2 Parameterization



2.7 Selecting the encoder type

For the CU250S-2 Control Unit, various encoder types can be connected. When connecting TTL and HTL incremental encoders usual for the CU240S Control Unit, new settings must be observed.

Parameter Action

p0400 3001: 1024 HTL A/B R 3002: 1024 TTL A/B R 3003: 2048 HTL A/B R 3005: 1024 HTL A/B 3006: 1024 TTL A/B 3007: 2048 HTL A/B 3008: 2048 TTL A/B 3009: 1024 HTL A/B unipolar 3011: 2048 HTL A/B unipolar 9999: user-defined

Diagram 2-5: Selecting incremental encoders that can be connected Different incremental encoders can be entered, user-defined using parameters p0401 to p0487.

2.8 Selecting technological units

Using parameter p0595, technological units can be selected, to which the technology controller is referenced.

Parameter Action

p0595 1: % 2: 1 referred (per unit), no dimensions 3: bar 4: °C 5: Pa 6: ltr/s 7: m³/s 8: ltr/min 9: m³/min 10: ltr/h 11: m³/h 12: kg/s 13: kg/min 14: kg/h 15: t/min 16: t/h 17: N 18: kN 19: Nm 20: psi 21: °F 22: gallon/s 23: inch³/s 24: gallon/min 25: inch³/min 26: gallon/h

Diagram 2-6: Dimensions that can be set for the technology controller

Technological values can be internally scaled to 100% using parameter p0596.

2.9 Operating hours counter

Using p0650, the actual operating hours can be read out and a maintenance interval activated in p0651. Alarm A1590 is activated after the time in p0651 elapses. The operating hour’s counter of the SINAMICS G120 in parameter p2114 has been changed:

Parameter Action

r2114[0] r2114[1]

Display milli seconds up to 86.400.000 ms (24h) Display days

The necessary calculation in the MICROMASTER with the runtime counter “upper word and lower word” has become invalid. A real time clock as realized in the MICROMASTER is not supported by the control units CU240B/E-2 and CU250S-2 of the SINAMICS G120. If a real time clock is required, it must be checked, whether the control unit CU230P-2 can be used, which has been especially designed for the branches HVAC and Water/Wastewater.

2.10 Digital inputs

Note The counting of the digital inputs has changed compared to the MICROMASTER MM440. Instead of the index number 1 for the first digital input the SINAMICS G120 starts with the index number 0.

2 Parameterization



2.10.1 CU240B/E-2 Control Unit

The potential of the digital inputs of the control unit CU240B-2 and CU240E-2 can be defined by the wiring of the inputs. For internal power supply

P-switching (PNP logic): Connect terminals 34 and 69 with terminal 28 M-switching (NPN logic): Connect terminals 34 and 69 with terminal 9

For an external power supply P-switching (PNP logic: Connect terminals 34 and 69 with the system

ground (GND) M-switching (NPN logic): Connect terminals 34 and 69 with the 24 V

supply.

Diagram 2-7: Function diagram, digital inputs of the CU240B-2 Control Unit

For the CU240E-2 Control Unit, in addition, the reference potential is divided into two terminals (DI COM and DI COM2).

Terminal 69 (DI COM): Reference potential for DI0, DI2 and DI4 Terminal 34 (DI COM2): Reference potential for DI1, DI3 and DI5

With this configuration fail-safe digital inputs (F-DI) of the control unit CU240E-2 and CU240E-2 F can be realized both p-switching or p- and m-switching.

2 Parameterization


Diagram 2-8: Function diagram, digital inputs of the CU240E-2 Control Unit

2.10.2 CU250S-2 Control Unit

The digital inputs of the control unit CU250S-2 are divided into two potential sections: - DI0 to DI6 with reference potential DI COM 1 - DI16 to DI19 with reference potential DI COM 3.

Diagram 2-9: Function diagram, digital inputs DI0 to DI6 of the CU250S-2 Control Unit

2 Parameterization



The digital inputs DI1, DI3, and DI5 have separate lead through (-) inputs. Using the digital inputs as fail-safe inputs switching to P24V (p-switching) the wiring according diagram 5-11 must be taken. If the fail-safe input shall be designed with one input switching to P24V (p-switching) and the other digital input switching to ground (m-switching), the positive inputs (+) inputs of DI1, DI3, and DI5 have to be connected to P24V, the negative (-) input of DI1, DI3, and DI5 is switched against DI COM 1. Besides the 7 digital inputs DI0 to DI6 with the potential DI COM1 there are another 4 digital inputs DI16 to DI19 with an own potential DI COM3. These digital inputs can be used as the digital inputs of the control units CU240B-2 and CU240E-2 as well as p-switching and also m-switching.

Diagram 2-10: Function diagram, digital inputs DI16 to DI19 of the CU250S-2 Control Unit

2.10.3 Forward/backward parameterization

For MICROMASTER MM440 Control Units, it was possible to wire the digital inputs directly via parameter p0701 to p0706 to specified functions forwards, and on the other side, using the BiCo wiring (selection p0701… p0706 = 99) to wire them backwards as required. For 2nd generation modules, forwards wiring is no longer possible; the digital inputs are wired in the required functions using display parameters r0722.0 … 27. In addition, the inverted inputs are available in parameters r0723.0 … 27.

2.10.4 Simulation Mode

The digital inputs and outputs can be simulated using parameter p0795.x.

STARTER The digital inputs and outputs can be set to the simulation state in the STARTER operating software.

2 Parameterization


Diagram 2-11: Simulation of the digital inputs/outputs using STARTER

Operator panel IOP The digital inputs and outputs can also be simulated using the IOP operator panel. Only two DI’s are displayed; however, by rotating the selector wheel, all of the existing digital inputs and outputs can be selected.

Diagram 2-12: Simulation of the digital inputs/outputs using the IOP

The actual state of the DI is displayed at the center; by entering "true" for the simulation, the DI is set as soon as "Activate simulation" was pressed.

Note Simulation mode is not possible with digital inputs, which are used as fail-safe digital inputs F-DI for safety applications.

2.11 Digital outputs

Note The counting of the digital outputs has changed compared to the MICROMASTER MM440. Instead of the index number 1 for the first digital output the SINAMICS G120 starts with the index number 0. Due to this the parameter numbers move one digit (e.g. DO0: MM440 = p731, CU240E-2 = p730).

The MICROMASTER MM440 Control Units have three relay outputs, each of which has a capability of 30V DC, 5A (resistive load) / 1AC250V, 2A (inductive load). Digital outputs DO0 and DO2 have NO and NC contacts, DO1 only an NO contact. Control units of the SINAMICS G120 are equipped as follows:

CU240B-2: DO0, NO and NC contacts, 30V DC, 0.5A (resistive load) CU240E-2: DO0, NO and NC contacts, 30 V DC, 0.5A (resistive load)

DO1, transistor output positive, 30 V DC, 0.5A (resistive load) DO2, NO and NC contacts, 30 V DC, 0.5A (resistive load)

2 Parameterization



CU250S-2: DO0, NO and NC contacts, 30 V DC, 0,5A (resistive load) DO1, NO contact, 30 V DC, 0,5A (resistive load) DO2, NO and NC contacts, 30 V DC, 0,5A (resistive load)

If digital outputs are required able to switch 1AC230V, it has to be checked, wether the control unit CU230P-2 can be used. The control unit CU230P-2 is equippped as following:

CU230P-2: DO0, NO and NC contacts, 30 V DC, 5A (resistive load) / 1AC250V, 2A (inductive load) DO1, NO contact, 30 V DC, 0.5A (resistive load) DO2, NO and NC contacts, 30 V DC, 5A (resistive load) / 1AC250V, 2A (inductive load)

As alternative interface modules can be used, e.g. 3TX... .

2.12 Analog inputs

Note The counting of the analog inputs has changed compared to the MICROMASTER MM440. Instead of the index number 1 for the first analog input the SINAMICS G120 starts with the index number 0.

2.12.1 Simulation mode

The analog inputs can be simulated using parameter p0797.x.

STARTER The analog inputs can be set to the simulation state in the STARTER operating software.

Diagram 2-13: Simulation of the analog inputs using STARTER

2 Parameterization


Operator panel IOP The analog inputs can also be simulated using the IOP operator panel. Only one DI is displayed; however, by rotating the selector wheel, all of the existing analog inputs can be selected.

Diagram 2-14: Simulation of the analog inputs using the IOP

The actual state of the AI is displayed at the centre; by entering a voltage value for the simulation, the AI is set to this value as soon as "Activate simulation" was pressed.

2.12.2 Dead band

For the MICROMASTER MM440 Control Units, when using analog inputs with 2 … 10V and/or 4 … 20mA, in addition to selecting the analog input via p0756.x, a dead zone can also be entered using p0761, so that the set point with values less than 2V/4mA does not run in the negative direction. For control units of the SINAMICS G120, this is no longer necessary; the response threshold for wire breakage monitoring can now be set using the parameter p0761.

Note For applications, where the dead zone was used to suppress interference voltages on the analog signal for example, from SINAMICS firmware version V4.6 and higher, it is now possible to parameterize a dead zone at the analog input using parameter p0764.x.

2.13 Analog Outputs

Note The counting of the analog outputs has changed compared to the MICROMASTER MM440. Instead of the index number 1 for the first analog output the SINAMICS G120 starts with the index number 0.

The analog outputs of the SINAMICS G120 can be parameterized as current source with 0 … 20mA, 4 … 20mA, and voltage source 0 … 10V compared to the analog outputs of the MICROMASTER MM440, which can only be used as outputs with current source.

2.14 Scaling of the set point channel

Contrary to the MICROMASTER MM440 Control Units, the set point channel is no longer scaled in Hz, but in rpm. This assumes that the rated speed and rated frequency were correctly entered during quick commissioning.

2 Parameterization



2.15 Motorized potentiometer

The motorized potentiometer now provides the option of saving analog set points. For example when an analog value fails as a result of wire breakage, the last set point can be directly accessed; an additional change is realized using the raise/lower keys.

Diagram 2-15: Function diagram of the motorized potentiometer

2.16 Second ramp function via the JOG ramp-function generator changed

It is no longer possible to implement a second ramp function by using the JOG ramp-function generator.

Note When using the data set changeover (DDS), up to 4 different parameterizable ramp functions are available. In operation, data sets can be changed over using digital inputs or also via the fieldbus. For details, refer to the operating instructions Link

2.17 Flying restart

Selection option regarding flying restart has been reduced.

http://support.automation.siemens.com/WW/view/de/50815575

2 Parameterization


Parameter Action

p1200 0: Flying restart inactive 1: Flying restart always active (start in the set point direction) 4: Flying restart always active (start only in the set point direction)

Diagram 2-16: Parameterization of the flying restart

2.18 Automatic restart

New functions have been implemented for the automatic restart.

Parameter Action

p1210 0: Inhibited automatic restart 1: Acknowledge all faults without restarting 4: Restart after line supply failure, without additional start attempts 6: Restart after fault with additional start attempts 14: Restart after line failure after manual acknowledgment 16: Restart after fault after manual acknowledgment 26: Acknowledging all faults and restarting for an ON command

Diagram 2-17: Setting options for automatic restart

Up to 10 fault messages can be set using parameter p1206, where the automatic restart is not started.

2.19 Expanded motor holding brake function

The parameterization of the motor holding brake has been expanded. Now, there are various modes available where the brake can be opened and closed as before from the process, however also permanently or depending on an external signal.

Note Only the CU250S-2 Control Unit supports the SBC safety function (Safe Brake Control).

2.20 Setting dynamic braking

With the MICROMASTER MM440, the default setting is deactivating the braking resistor and activating the Vdcmax controller. The activation of the dynamic braking by parameter p1237 could be done in several steps of 5/10/20/50/100%. The Vdcmax controller had to be deactivated by parameter p1240. With the SINAMICS G120 the Vdcmax controller is activated by default. Using parameter p0219 enables dynamic braking. This parameter automatically sets the regenerative power and the down ramp, further, it inhibits the Vdcmax controller. Compared to the MICROMASTER, which was parameterized in % on time, the SINAMICS G120 is parameterized in kW.

2 Parameterization



2.21 Control modes

Control modes Selecting the control modes using parameter p1300 has been supplemented by ECO versions with flux reduction.

Parameter Action

p1300 0: U/f control with linear characteristic 1: U/f control with linear characteristic and FCC 2: U/f control with parabolic characteristic 3: U/f control with parameterizable characteristic 4: U/f control with linear characteristic and ECO 5: U/f control for drives requiring a precise frequency (e.g. textiles) 6: U/f control for drives requiring a precise frequency and FCC 7: U/f control with parabolic characteristic and ECO 19: U/f control with independent voltage set point 20: Speed control (without encoder) 21: Speed control (with encoder) 22: Torque control (without encoder) 23: Torque control (with encoder)

Diagram 2-18: Selectable control modes

Note Control modes 21 with encoder (speed control with encoder) and 23 (torque control with encoder) are only possible when using the CU250S-2 Control Unit.

Parameterizable v/f characteristic The MICROMASTER MM440 Control Units each have 3 voltage/frequency points along a characteristic. Contrary to this, control units of the SINAMICS G120 have 4 voltage/frequency points, which means that the characteristic can be more finely parameterized.

If the additional points are not required, points 3 and 4 can be set the same value.

2.22 Voltage boost

The set voltage boost for V/f characteristics with linear or square law characteristic are extended up to the rated operating point, depending on the characteristic selected. The final boost frequency, which was able to be set using parameter p1316, is no longer available.

Note As a result of the different voltage boost version, the settings should be checked in order to avoid an unnecessary motor temperature rise.

2 Parameterization


2.23 Speed-dependent controller adaptation

For control units of the SINAMICS G120, the Kp and Tn components of the speed controller can be adapted depending on the speed or a freely selectable value.

Diagram 2-19: Function diagram Kp and Tn adaptation of the speed controller

2.24 Motor data identification

Motor data identification under parameter p1900, was supplemented to include a selectable rotating measurement.

2.25 Change for reference quantities

The reference quantities (p2000 … 2004) are valid for control units of the SINAMICS G120s as standard for all data sets. In addition, the reference quantities have been expanded to include the reference temperature (p2006). In the CU240E-2, the speed set point and actual value is no longer referred to Hz but to rpm; this means that the required speed no longer has to be converted into a frequency.

2 Parameterization



2.26 Free Function Blocks

Note The activation and prioritization of the free function blocks by the parameters p2800[x] and p2801[x] has been replaced by an individual release for the individual function block , run groups with defined sampling time and determining the sequence to the sequence group.

Figure 2-1: Run groups of the free function blocks

The scope and functionality of the free function blocks were expanded significantly against the MICROMASTER MM440. As a result, a shift of parameter numbers was necessary.

Note Due to the increased size and the increased functionality of the free function blocks the necessary parameters have been moved to the 20,000 upwards.

Note In the free function blocks for numerical operations, the inputs with values in % are occupied; the outputs show the number value. In a further interconnection these numerical values are automatically converted again in% values.

2.27 Technology controller

The technology controller was expanded to implement normal as well as inverse control operations.

Normal control sense: As long as the actual value is less than the set point, a positive system deviation results in a positive drive speed.

Inverse control sense: As long as the actual value is greater than the set point, a positive system deviation results in a positive drive speed.

Parameter p2306 is used to change over the control sense.

2.28 Fixed set points that can be freely used

Using parameters p2900 and p2901, fixed set points that can be freely used, can be defined in the range +/- 100.00%. Further, permanently defined fixed set points are already available in r2902 [0 … 14].

2.29 Change, deactivating the BF-LED

If a fieldbus is not being used, then the BF-LED can be deactivated using parameter p2030 0. For more detailed information, see Link


2 Parameterization



2.30 Positioning down ramp has been eliminated

The positioning down ramp available in the MICROMASTER MM440 (parameters p2480 ... p2488) is no longer available.

Implemented using rapid traverse/crawl changeover based on free function blocks.

3 Performance vector control


3 Performance vector control 3.1 Increased ruggedness of the vector control

For encoderless vector control of the CU240S, for critical applications, such as raising and lowering, the motor data had to be optimized a multiple number of times, taking into account equivalent circuit diagram data. Tests carried out on gantry cranes indicated that the equivalent circuit diagram data for the CU240E-2 Control Units were precisely determined with the first MotID, so that post optimization was no longer required. This indicated that the vector control of the SINAMICS pool is significantly more stable than the vector control of the old software pool.

3.2 Vector control without encoder SLVC (sensorless)

Diagram 3-1: Comparison of the control performance for CU240S and CU240B/E-2, CU250S-2 for vector control without encoder

We do not recommend using torque control without encoder; instead, speed control can be used with torque limiting.

4 Communication


4 Communication

Note For MICROMASTER MM4 it was possible to control both the inverter via the RS485 interface via USS protocol or via the optional communication module by the fieldbus. The SINAMICS G120 offers only a fieldbus interface for control. The commissioning is done via a USB connection.

4.1 PROFIBUS DP

MICROMASTER MM4 and SINAMICS G120 support different versions of the PROFIDRIVE profile:

MICROMASTER MM4 Version V2.0 and V3.0 SINAMICS G120 Version V4.1

This has the consequence that the contents of the control and status words have changed. Also the feedback of the status word has changed at power on. Existing programs for the cyclic control of a MICROMASTER MM4 via PROFIBUS DP can be used in the following cases for the SINAMICS G120 control units:

For communication the standard telegram 1 or the telegram type PPO3 is used, which corresponds to the telegram 1 of the SINAMICS G120. If other PPO types were used, these can be converted using the Siemens-telegrams 350 to 354. When modules of the product Drive ES SIMATIC were used in SIMATIC S7 program, the "Generate DRIVDBx " configurator must be run again to update the layout slot ( slot combination separate slots).

The bits 08 and 09 of the control word STW1 for „Jog right“ and „Jog left“ are not used

The starting sequence of the converter is checked, changed structure of the bits see ID 28518735

If acyclical communication parameters are accessed, possibly an adaptation by modified parameter numbers is required.

4.1.1 GSD Files

New GSD files are required for the SINAMICS G120. These can be downloaded at the following link ID 23450835

4.1.2 Routing across a CPU

For routing across network boundaries (IE to Profibus DP), the CPU must support the data set routing protocol. In addition, as before DriveES Basic is required, also STARTER from version V4.3 with Service Pack SP2. The following CPUs support data set routing:

- ET200S IM151-8 PN/DP CPU in conjunction with DP master module

- SIMATIC S7-300 CPU313C-2 DP from version V3.3 onwards

- SIMATIC S7-400 CPU´s from version V5.1 onwards - WinAC RTX from version 2010, Update 1 with CP5603,

CP5613 or CP5623

Note Presently, the following systems do not support data set routing: SIMATIC S7-1200 WinAC MP SIMOTION

A complete and timely updated list of all DS- routable assemblies is available in Siemens Product Information System ( ProdIS / SIOS ) under ID 7000978.

4.1.3 Teleservice

4.1.3.1 Teleservice via a CPU

Figure 4-1: Teleservice via a SIMATIC CPU

4 Communication


For this, a Teleservice Adapter II and a CPU listed under routing (see chapter 4.1.2), which supports data set routing, are required.

Note Routing (data set routing) from MPI/DP to PROFINET is NOT possible.

4.1.3.2 Teleservice directly via the fieldbus

Figure 4-2: Teleservice directly via fieldbus

For this configuration, the Teleservice Adapter is directly connected at the fieldbus. In this case, it is of no significance whether the CPU supports data set routing.

For Control Units with PROFINET connection CU240E-2 PN and CU250S-2 PN, Teleservice is possible via Teleservice Adapter IE Basic.

Note For PROFIBUS, teleservice is presently not possible, as Teleservice Adapter II does not support the functionality.

4.1.4 Direct HMI connection

Directly connecting an HMI to read out and change drive parameters, without intermediate CPU, is not supported.

Note The parameters must be read out of the converter by the CPU, and from there, transferred to the HMI.

4.1.5 Integration into the Process Control System SIMATIC PCS7

Integration of the SINAMICS G120 into the process control system SIMATIC PCS7 has to be processed by another telegram and another PCS7 module as used together with the MICROMASTER MM440.

4.2 USS Protocol

The different versions of the PROFIdrive profile have the same influences onto the communication as with PROFIBUS DP (see chapter 4.1).

4.3 DeviceNet

For the communication of MICROMASTER MM440 DeviceNet there is no direct replacement. There are the following alternative options:

Use of a gateway, e.g. HMS Industrial Networks GmbH Switch over to Ethernet/IP together with a control unit with PROFINET.

Ethernet/IP uses also the „Common Industrial Protocol“ CIP defined by ODVA.

4.4 CAN Bus

Applications of MICROMASTER MM440 with the CANopen communication module can be replaced by the Control Unit CU250S - CAN 2 of the SINAMICS G120 For applications with low digital inputs and outputs, and without encoder feedback, the SINAMICS G120C is recommended as an alternative in the power range from 0.55 to 18.5 kW.











5 Drive fault messages


5 Drive fault messages The fault messages of the control units of the SINAMICS G120s have changed with respect to the CU240E and CU240S. If these are to be displayed at an HMI for diagnostic purposes, then the corresponding fault texts can be downloaded from the following link Link. In addition, it is now possible to hide certain fault messages or convert them into alarms. The acknowledgment mode can also be adapted.
