FANUC A06B-6200-H026 is an αiPS 26-B regenerative power supply module for compatible FANUC αi-B servo and spindle amplifier systems. It converts three-phase AC input into the shared DC-link power required by connected CNC drive modules.

The module accepts 200–240VAC input and provides a rated 283–339VDC output with 31kW capacity. It is a power supply module, not an axis servo amplifier; the connected αiSV and αiSP modules perform motor control.

A06B-6200-H026 Product Specifications

αiPS 26-B Power and Regeneration Function

A06B-6200-H026 supplies the common DC bus used by compatible αi-B servo and spindle amplifiers. During motor deceleration, its regenerative circuit returns braking energy to the incoming power system instead of relying only on resistor dissipation, supporting efficient multi-axis CNC operation.

Replacement Compatibility

Confirm A06B-6200-H026 on the original nameplate together with the αiPS 26-B designation. Do not select A06B-6200-H015, H030 or A06B-6202-H026 only because the housing or capacity appears similar. Verify the CNC generation, connected servo and spindle modules, DC-link arrangement, AC reactor, connectors and control software.

Testing and Installation Notes

REACO CNC checks the label, housing, power stage, pre-charge circuit, DC-link output, regenerative operation, fans, communication and alarm display as applicable. Incoming voltage, phase balance, grounding, reactor and magnetic-contactor wiring must meet the machine specification.

Installation must be performed by qualified personnel. Isolate incoming power and wait until the charge indicator is off before handling the DC link. Related resources: FANUC power and drive modules and FANUC CNC drive repair service.
