Advanced settings
For characteristic 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).

Loading the standard inverter characteristic
If an incorrect inverter characteristic has been determined or none at all, it is possible to load a
device-typical standard inverter characteristic.

How to load the standard inverter characteristic:
1. Set object 0x2822 (or 0x3022 for axis B) to "1".
• The progress of the procedure is shown in object 0x2823 (or 0x3023 for axis B).
2. For permanent storage: After completion of the procedure, upload the inverter
characteristic set in 0x2947 (or 0x3147 for axis B) 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 ( 60)
