The Fuji Electric 6MBP150VCC060-51, cross-referenced as FANUC A50L-0001-0437, is a 600V, 150A intelligent power module (IPM) used in compatible FANUC CNC power-conversion and motor-drive assemblies. Its six-switch IGBT configuration combines the inverter power stage with integrated gate-drive and protection functions.

Use the Fuji nameplate as the primary identifier and the FANUC A50L number as its cross-reference. Both numbers and the terminal layout should match the original.

6MBP150VCC060-51 Product Information

Integrated Inverter Power Stage

The six internal IGBT switches form a three-phase inverter bridge that converts the drive DC bus into controlled motor output. Integrated circuits drive the IGBTs and help the host board monitor abnormal operating conditions. Actual switching frequency and motor capacity depend on the complete FANUC drive.

Model and Replacement Compatibility

Confirm 6MBP150VCC060-51 and A50L-0001-0437 on the original labels. Compare the terminal pattern, control pins, baseplate, mounting holes, package height and connected amplifier board. Do not substitute 6MBP150VCA060-51, 6MBP100VCC060-51 or another A50L module because similar housings can have different ratings, pin assignments or internal control circuits.

Testing and Installation Notes

REACO CNC checks the housing, terminals, baseplate, insulation and static electrical characteristics, followed by compatible drive testing when available. Installation requires ESD precautions, a clean flat heatsink, suitable thermal compound and the specified screw torque. Qualified personnel must isolate power and verify that the DC bus is fully discharged before service.
