We have two 590P-23 and 590P-53 drives with LinkNET Tech Boxes installed and armature voltage speed feedback enabled.
Utilizing the same configuration, the 590P-53 works well, however, the 590P-23 outputs half the commanded armature voltage.
36V reference, measured 18V:
70V reference, measured 35V:
In the Manual, I noticed the following text:
For the 590P-23 drive and a 200V rated motor, do I have to set the NOM MOTOR VOLTS parameter to 400V and divide ARM VOLTS FBK by two to get the real armature voltage?
