Current Regulator and Motor Adjustment

Caution
Incorrect settings of the current regulator parameters and current limits can destroy the
motor and, possibly, also the motor controller within a very short time!
Overview
The parameter set of the motor controller must be adapted for the connected motor.
Caution
If the phase sequence is distorted in the motor or angle encoder cable, the result may
be positive feedback, so the speed in the motor cannot be regulated. The motor can
turn uncontrollably!

This value can be taken from the motor rating plate and is entered in milliamperes. The effective value
(RMS) is always assumed. No current can be specified above the motor controller nominal current.
