The FANUC A06B-0126-B177 is an αC6/2000 AC servo motor for CNC machine-tool feed axes. It combines 0.6kW output, 2000rpm rated speed, a tapered shaft, an 8N·m holding brake and an αI64 incremental pulse coder.

A06B0126B177 is the compact search form of the same ordering number. Use the complete hyphenated nameplate model as the primary identifier for quotation and replacement.

αC6/2000 Servo and Feedback Function

The motor converts amplifier commands into controlled feed-axis motion, while the αI64 coder supplies incremental position feedback. The brake holds an axis when servo control is off; it is not a service brake for routine machine deceleration.

Exact-Model Replacement Checks

The order code is configuration-specific: “0126” identifies αC6/2000, “B1” specifies the tapered shaft with 8N·m brake, and “77” identifies the αI64 coder. Do not substitute A06B-0126-B077, B175 or a straight-shaft version because the base motor matches. Verify the full nameplate, shaft, brake, connectors, coder, mounting and compatible FANUC amplifier.

Testing and Installation Notes

REACO CNC checks the nameplate, shaft, flange, connectors, insulation, windings, brake release, coder feedback and running condition as applicable. Qualified personnel should isolate power, support the machine axis and follow FANUC brake-circuit requirements before replacement.
