How to carry out the motor parameter identification:

1. If the controller is enabled, inhibit the controller.

Enable/inhibit operation via control word

( 59)

2. Set object

0x2825

(or

0x3025

for axis B) to "9" to change to the "Motor: Parameter

identification" operating mode.

3. Enable the controller to start the procedure.

Note: By means of controller inhibit, the procedure started can be cancelled any time, if

required, without a change in settings.

After successful completion...
...the controller is automatically inhibited and the determined motor data are set in the

corresponding objects (

0x2C01

and

0x2C02

or

0x3401

and

0x3402

for axis B).

• For permanent storage, the changed settings must be uploaded to the controller from the i700

servo inverter.
The »EASY Starter« serves to save the parameter settings of the i700 servo inverter as parameter

file (*.gdc). In the »PLC Designer«, this file can then be imported in the corresponding axis.

• The controller inhibit automatically set by the procedure can be deactivated via the

Controlword (

0x6040

or

0x6840

for axis B) (setting = 7, 15).

In the event of an error
If an error occurs during the procedure or the pulse inhibit gets active (e.g. due to short-time

undervoltage), the procedure is terminated with controller inhibit without a change in settings.

Advanced settings
For motor parameter detection, the current controller is parameterised automatically at the

beginning of the identification process. For motors with a very low stator leakage inductance

(< 1 mH), an automatic parameter setting may fail and the actual identification process is aborted

with an error message like e.g. "short circuit".

• For such a case, it is possible to set the current controller manually via the object

0x2942

(or

0x3142

for axis B).

• Whether the current controller is to be selected automatically or the values below

0x2942

(or

0x3142

for axis B) are active, is selected via the object

0x2DE0:1

(or

0x35E0:1

for axis B).
