Motor and Feedback Function

The A06B-0373-B075 receives controlled power from a compatible FANUC servo amplifier and produces accurate rotary movement for a machine axis. Its A64 absolute pulse coder returns position and speed information to the servo-control system.

Absolute-position retention depends on the appropriate CNC or servo-amplifier backup battery. Battery condition and the correct encoder-disconnection procedure should be checked before motor removal.

2/3000 Model Clarification

The A06B-0373-B075 is the Alpha 2/3000 version rated for 3,000 min⁻¹. It should not be confused with the A06B-0372-B075 Alpha 2/2000, which has a different output-speed and motor specification.

Although both models may use a tapered shaft and A64 feedback, they should not be interchanged without confirming the original machine specification, servo amplifier and CNC parameters.

Related Feedback and Shaft Versions

Modification-Suffix Notice

This motor may appear with suffixes such as #0075, #7075, #C008, #C076 or #U075. Depending on the suffix, the unit may have different nameplate markings, approvals, keyway or sealing modifications.

For an exact replacement, compare the complete FANUC number on the original nameplate. Specifications associated with an IP67 or keyed-shaft suffix should not be applied automatically to the unsuffixed A06B-0373-B075.
