Examples of feedback device and switch wiring
Fully wired port with differential incremental encoder, hall sensors and switches
Wiring of differential incremental encoder
Minimal wiring of incremental encoder (single ended, no index channel)
Wiring of Hall sensors only (only torque mode possible)
Illustration of wiring limit and home switches. In addition to this, encoder and/or halls are needed.
 | In case of single-ended encoder, connect encoder's A, B, Z only to drive's A+, B+ and C+ and leave drive's A-, B- and C- unconnected. |
| With differential Hall sensor (which provides U+, U-, V+, V-, W+ and W-, connect only sensor's U+, V+ and W+ to drive's HALL_U/V/W. |
| Never connect sensor negative outputs (A-/B-/C-/U-/V-/W-) to GND. Connect them to drive's A-/B-/C- or leave unconnected. |
 | Feedback devices with differential signaling may use varying naming schemes of signal pairs. For example differential signal X (which contains two electrical wires) may be denoted as: X+ and X-, or X and \X or X and X. In this Wiki we mark them X+ and X-. Some Fanuc encoders have quadrature signals named as PCA, /PCA, PCB, /PCB, PCZ and /PCZ which are equivalent to A, B and Z signal pairs. |
