Example 3

Encoder connected to X55 for positioning loop. Since the
encoder is not mounted directly on the motor shaft, a 2nd
encoder connection (X56) is needed for running closed FC
speed control loop.

Example 4

Resolver feedback used. MCB 103 option is needed. FC
speed control loop must be closed.
