How to carry out the motor parameter identification:
1. If the controller is enabled, inhibit the controller.
Enable/inhibit operation via control word
2. Set object
(or
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 (
and
and
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.
Saving changed parameters safe against mains failure
• The controller inhibit automatically set by the procedure can be deactivated via the
Controlword (
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
(or
for axis B).
• Whether the current controller is to be selected automatically or the values below
(or
for axis B) are active, is selected via the object
for axis B).
