FANUC A50L-0001-0209 Transistor module. This specially packaged power transistor is known by Fuji Electric 6DI150A-060 and belongs to the DI series of modules. This transistor is in an M type package solely for FANUC. Fitting on various FANUC AC spindle drives from 12kW through to 30kW versions. Rated at 150amp 600 volt. They were natively coupled with digital 0-MA, 0-TA. 0-TB, 0-TC and earlier 0-C/0-D control series.
Be careful when ordering replacement 6DI150A-060 Fuji transistors; there are subtle variations in the wrong package (size/shape). We have found out and had to redesign our own power boards for the base section of the A06B-6059, 6060, 6062 and 6063 spindle amplifiers to accomodate. Probably still got a box or two of the wrong transistors buried somewhere in the building. We only sell the correct Mxxx package version of the A50L-0001-0209 transistor module to fit in the drive it was designed for.
If you do order a transistor or more and they don’t solve your problems or you blow them up then obviously other parts of the spindle were faulty. Not that uncommon. Contact us for either an exchange or for a price quote for testing and repair on your spindle drive. If you are unsure about your spindle alarms presented on the drive, then contact us
