Motor controller settings

8.4.4 Motor controller settings
After the motor settings have been made, the different control loops must be set. For a quick
commissioning, the calculations and settings are made automatically if one of the following
optimisations is carried out:
4Motor selection from motor catalogue
4Automatic motor identification (energized)
4Automatic motor calibration (non-energized)

8.4.4.1 Current controller
For a quick commissioning, the calculations and settings are made automatically during the
optimisation.
For typical applications, a manual adaptation of the parameters of the current
controller is not recommended. A wrong setting may have a negative effect on
the control. For special applications, contact the manufacturer before adapting
the parameters.
Preconditions
The current controller parameters are calculated based on the stator resistance and leakage
inductance. Thus, the following parameters must be set correctly, either via optimisation or
manually (according to manufacturer-data/motor data sheet):
0x2C01:002: Stator resistance
•
0x2C01:003: Stator leakage inductance
•
