A1. 2 Communication Setting up

To display the status and parameters or set up parameters communication between computer and servo drive is

required. For this purpose, LIVE I.C.E supports 2 way of communication, USB and RS-422.

① Connect USB Cable (A-mini b type) or RS-422 cable between computer in which LIVE I.C.E is installed and drive.

If USB communication is used USB cable must be connected to CN5 and RS-422 communication is used, RS-422

cable must be connected to CN4 of L7 Drive, respectively. If computer has only RS-232C port , RS-232C to RS-422

converter is required.

④ Select Communication method between ‘General USB’ and ‘RS-422’. For both USB and RS-422, setting up the Node

Number (P0-05, System ID) is necessary and for RS-422 communication, selecting Baud Rate (P0-04) is necessary.

③ Select ‘Communication Setting’ in Communication menu and Communication Setting window will be displayed.

⑤ Select Connect in Communication menu.

⑦ Due to trouble in cable, setting up different node number from P0-05 for both communication or selecting different

Baud Rate from P0-04, message depicted below will be displayed. When message below is displayed, check the cable,

number for both communication and 1 more item, Baud Rate for RS-422 communication.

⑥ If communication is executed normally, progress bar will be moved left and right.

A1.4 Parameter Setting

Parameters of L7 servo drive can be set up with LIVE I.C.E. The parameters of L7 servo drive are composed of 7

groups, St, P0 ~ P4 and Cn group. Because St group is composed with monitoring(read only) data, data in St group

cannot be edited and Cn group is composed with operating data, the data in Cn group cannot be edited.

Finally, data in P0 ~ P4 can be edited with LIVE I.C.E. To edit parameters, select Parameter Editing in Parameter menu.

When Parameter Editing in Parameter menu is selected, all parameters will be read. When reading is completed, data

will be displayed in Parameter Editing window.

Group selection

* When setting up parameters and writing is completed, resetting servo drive may required depending on changed

parameters.

A1.5 Manual Test Operation

Test operation (JOG operation) can be executed with LIVE I.C.E. To execute test operation, select Manual Test

Operation in Operation menu and Manual Test Operation window will be displayed..

① Set operation speed with slide bar or type number in text box with RPM unit.

Never set speed over than Max. speed of servo motor.

② If this button is not clicked, setting speed will not be applied to servo drive.

③ When this button is clicked, confirm message will be displayed as depicted below.

‘Yes’ is selected in confirm message, servo will be ON state regardless of Servo ON signal and automatically OFF

when test operation is completed.

④ LOCK/UNLOCK will be toggled whenever LOCK/UNLOCK button is clicked.

When LOCK is displayed, STOP button will be disabled. Servo motor will rotate forward or reverse direction while

Forward or Reverse button is clicked, and servo motor will stop when the button is released.

And if UNLOCK is displayed, STOP button will be enabled. Servo motor will rotate forward or reverse direction when

Forward or Reverse button is clicked, and servo motor will not stop although the button is released. To stop servo motor

STOP button must be clicked.

⑤ Operating Speed will be displayed when servo motor is rotating

A1.6 Gain Auto Tuning

Inertia Ratio is the ratio of load inertia to rotor inertia. This state means that inertia ratio of non-loaded motor is 100%.

Because inertia ratio is very important control parameter for servo system, it must be calculated as precise as possible

for optimal servo operation. With Auto Tuning function of LIVE I.C.E, Inertia Ratio can be found.

To execute gain auto tuning function, select Gain Auto Tuning in Operation menu.

① Select Tuning Target Distance with slide bar or type number in the text box. Available number range is 1 ~ 5.


A1 - 20

② Select Tuning Speed with slide bar or type number in the text box. Available number range is 8 ~ 10 and its unit is

100 rpm. If 8 is selected, servo motor will rotate with 800 rpm speed.

③ If Apply button is not clicked, selected distance and speed will not be applied to servo drive. To apply selected distance

and speed, click Apply button after selecting distance and/or speed.

④ When Start button is clicked, confirm message depicted below will be displayed. ‘Yes’ button in confirm message is

clicked, motor will rotate 3 times of forward and reverse direction with assigned speed and distance. When auto tuning

is completed, another message window, completion message window, will be displayed.

⑤ Progress bar will be displayed while auto tuning is executed.

⑥ Inertia ratio set up in P1-00 prior to auto tuning will be displayed.

⑦ Inertia ratio calculated while auto tuning is executed will be displayed after auto tuning is completed.

Because calculated inertia ratio is not copied to P1-00 automatically, the value must be edited manually.

A1.7 O/S Upgrade

Operating System of L7 Drive can be upgraded with LIVE I.C.E. When O/S upgrade is executed, for safety, it is strongly

recommended to disconnect servo motor power cable and encoder cable.

And when O/S upgrade is executed all parameters will be initial value, backing up of parameters is also recommended.

To execute O/S upgrade, select OS Upgrade in OS menu. O/S Upgrade is selected, Caution message for O/S upgrade will

be displayed. Read the caution message carefully and click Ok button. O/S upgrader program will be executed.


A1 - 22

① Select file path in which O/S file is stored. When button at right side is select, file open dialog will be displayed.

② Progress bar will be displayed while O/S upgrade is executed.

③ Type Node ID which is set up in P0-04.

④ O/S upgrader tool is different from LIVE I.C.E. After confirming Node ID, click ComSet button. And Ready button will be

enabled.

⑤ When Ready button is clicked, LED of servo drive will display ‘boot’. Never turn off the power of servo drive when ‘boot’

is displayed in servo drive LED. Turning off servo drive power can be the reason of serious damage in servo drive.

⑥ Downloading will be started when Download button is clicked. Downloading is completed completion message will be

displayed. Reset servo drive and download backed up parameter when O/S upgrade is completed.
