*The shield connections of the feedback cable should be connected to the Compax3 Feedback X13 header's metal housing (if possible).
***The wire colors may not apply to your cable. Option 1 resolver cable wire colors can vary, however, the wire function should be consistent among all cables. If your cable wire marker (labels) are no longer present or readable, please contact Parker.

Notes:
Motor Setup - the Option 1 motors are included in the C3 ServoManager motor files. Therefore, no additional steps are required in the controller. However, you may want to verify your wiring by running the C3 - MotorManager from within C3 ServoManager. Once in the C3 - MotorManager, expand the Motor commutaion tuning branch and choose Verify position sensor angle. Run the algorithm and verify the Detected Values in window 4/4 of the procedure are correct. The Configured Values should be close to the Estimated Values(measured).
Resolver/Encoder Out Polarity - resolver will count positive when the motor shaft rotates clockwise. Also, the encoder output signals on the X11 connector, pins 13&14(Z) 8&12(B) 6&7(A), will count in the positive direction as well. Therefore, a clockwise rotation of the shaft will increase resolver counts when Actual Position (object 680.5) is queried on the drive, and will increase the encoder counts sent out of the drive to an external device connected to X11.6K Controller connection - the encoder output (X11 encoder out pins) 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 (X11 encoder out pins) 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).
