Notes:
Motor Phase Connection - Because the commutation cycle for the MaxPlus (MPM) servo motors is different than the legacy Compumotor servo motors, the motor phase leads must be switched on Phase B and Phase C in order to get proper commutation between the Apex Drive and the MaxPlus.
Resolver/Encoder Out Polarity - resolver will count positive when the motor shaft rotates clockwise. Also, the encoder output signals on the Encoder Out connector will count in the positive direction as well. Therefore, a clockwise rotation of the shaft will increase resolver counts when Actual Position is queried on the drive/controller version, and will increase the encoder counts sent out of the drive to an external device connected to the Apex drive only.6K Controller connection - the Encoder Output counts correctly to a positive commanded input on the Compax3, therefore, we do not need to make any adjustments to the feedback in the 6K (ENCPOL0).
ACR Controller connection - the Encoder Output counts correctly to a positive commanded input on the Compax3, therefore, we do not need to make any adjustments to the feedback in the ACR (MULT is positive).
