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 inverter disable without the settings being
changed.

Extended settings for identification

For determining the characteristic, the current controller is automatically parameterised at
the start of the identification process. In case of motors with a very low stator leakage induc-
tance (< 1 mH), the automatic parameterisation can fail and the actual identification process
is aborted with an error message such as "short circuit".
For this case, it is possible to set the current controller manually via the

Load standard inverter characteristic

If none or only one faulty inverter characteristic could be determined, a device-typical stand-
ard inverter characteristic can be loaded.
How to load the standard inverter characteristic:
1. Axis commands: load standard-Lh saturation characteristic
2. After completing the procedure, save the inverter characteristic set in in the inverter.
The »EASY Starter« serves to save the parameter setting of the inverter as parameter file
(*.gdc). 4Saving the parameter settings
