Chapter 3 Connectors
Motor Feedback The Table 46 compares the motor feedback connector pinouts for the
Kinetix 300 (motor feedback connector) and Kinetix 5100 servo drives (MFB
connector). Both the Kinetix 300 drive and Kinetix 5100 drive accept motor
feedback signals from Hiperface and Generic TTL incremental encoders. The
Kinetix 300 drive also supports 17-bit serial encoders. The Kinetix 5100 drive
supports both 17-bit serial encoders and 24-bit serial encoders.

(1) Determine which power supply your encoder requires and connect to that supply only. Do not make connections to both supplies.
(2) Not applicable unless motor has integrated thermal protection.
