Limitation Of Modulation Controller - BONFIGLIOLI ACTIVE CUBE 201 Operating Instructions Manual

18.5.7.1 Limitation of modulation controller

The output signal of the modulation controller is the internal reference flux. The controller output and
integrating component are limited via parameter
Rated Magnetising Current
Current is to be set to the rated value of the machine. For the lower limit, select a value which also
builds up an adequate flux in the machine in the field weakening area. The limitation of the control
deviation at the output of the modulation controller prevents a possible oscillation of the control loop
in the case of load surges. The parameter
value and acts both as a positive and a negative limit.
