FANUC A50L-0001-0433 identifies the Fuji Electric 6MBP80VCA060-51 intelligent power module. This VCA Series six-switch IGBT module is rated at 600V and 80A for the inverter power stage of compatible FANUC Alpha i amplifier hardware.

A documented application is the FANUC Alpha iSV 80/80 servo amplifier. The module is also associated with selected Alpha i spindle amplifiers and power-supply modules. Confirm the complete A06B host because the -51 suffix identifies a FANUC-specific package.

A50L-0001-0433 Product Information

Three-Phase Inverter Power Stage

The 6MBP80VCA060-51 integrates six IGBT switches with associated control and protection circuitry for three-phase motor power conversion. Its V-Series design supports low power loss, soft switching and direct IGBT junction-temperature monitoring.

Compatibility and Module Matching

Confirm both A50L-0001-0433 and 6MBP80VCA060-51 on the original module. Compare the complete A06B amplifier number, terminals, control connector, baseplate and mounting holes. Do not substitute 6MBP80VCA060-01, 6MBP80VBA060-51, A50L-0001-0436 or other modules because their housings appear similar.

Testing and Installation

REACO CNC checks the labels, housing, terminals, baseplate, insulation and electrical characteristics before shipment. Installation requires a clean heatsink, correctly applied thermal compound and specified mounting torque. Qualified personnel must isolate power and confirm the DC bus is fully discharged before service.
