Aux Feedback Description: The feedback type for a machine mounted feedback device is found in parameter 115. The
resolution of the machine mounted feedback device is found in parameter 117 for both rotary and linear devices.
Parameter 503 is used to provide additional auxiliary feedback information.
Structure of motor feedback type:
Bits: 3-0: 0000 = No Feedback
0001 = SRS_60 Single turn absolute 1024 S/C per rev
0010 = SRM_60 Multi-turn absolute 1024 S/C per rev
0011 = SCS_60 Single turn absolute 512 S/C per rev
0100 = SCM_60 Multi-turn absolute 512 S/C per rev
0101 = SNS_60 High resolution incremental 1024 S/C per rev
1000 = Analog Reference +/- 10V dc differential
1001 = Sin/Cos Generic linear or rotary S/C device w/index
1010 = TTL Generic linear or rotary TTL A quad B device w/index
Analog reference must be chosen whenever the drive is configured for an analog command reference.
