Fanuc Alpha Series AC Servo Motors (view source)

== Overview ==
Fanuc "red cap" servos that typically use proprietary serially interfaced (RS-422) high resolution encoders. Some of them are absolute with battery backup, and some are "incremental". I believe both of them have some level of absolute resolution (10-bit?) per turn for commutation purposes (these motors have no hall sensors).
== Specifications ==
In the "65142E/04" manual:
[https://s3.amazonaws.com/Icarus/DOCUMENTS/Fanuc_Manuals_1113.pdf#page=122 Pages 122-140] (109-127 in the PDF) show the specifications for different models.

TODO: find out where the details of the wiring from the 17-pin connector to the encoder's internal 14-pin connector are documented.

Cable side plug:

=== Encoder ===
[https://s3.amazonaws.com/Icarus/DOCUMENTS/Fanuc_Manuals_1113.pdf#page=81 Page 81-85] (66-70 in the PDF) have information about the two types of built-in encoders, the absolute "A64" and the incremental "I64".
The "I64" encoder's Fanuc part number seems to be "A860-0365-V501", or "A860-0365-T101" when bundled with the external circular connector to internal rectangular connector cable.
The external round jack to internal rectangular plug cable assembly's part number when bought individually is "A860-0360-V906". It's half made up of the above mentioned Hirose H/MS3102A20-29P(73) receptacle, the rectangular connector plug is yet to be identified.
Possible encoder cover part numbers: "A290-0511-X053" or "A290-0511-X054".
