Feedback systems

Several feedback systems can be connected to the controller and configured:
( Armature voltage control
( DC tacho feedback
( Resolver feedback
( Encoder feedback
DC tacho feedback
Tacho signals are connected via term. 3/4 of terminal block X1. The controller
processes rated tacho voltages of 10...180V (chapter 4.3.5.1).
Resolver feedback (X7)
( 2-pole resolver (V = 10 V, f = 5 kHz)
( Connection to a 9-pole Sub D socket X7
( Resolver cable and resolver are monitored for wire breakage (fault message
