Degeneration transistor type for Mazak Integrex 50 spindle drive power unit

Hello,

replacing a regeneration transistor from Mazak Integrex 50 spindle drive power unit (MDS-A-CV-300). The label on the transistor unit is missing. Anyone know the exact part type number?



Would really much appreciate this information.

Deceleration perhaps ?

Yes that, or what I meant to write was regeneration.

Thanks for that 'cuz I was thinking … I've never heard of a "Degeneration Transistor"... BUT there is specific "Degeneration* technique " on a common Emitter junction of transistors that actually has a useful purpose.


So was a bit confoooosed there.


It's basically a power transistor that you are looking for ?

So I thought maybe EngineerFarmer knows it is emitter degeneration semiconductor for current output ? / knows his onions batter than I do... [Sometimes that arrangement is used in a negative feedback loop 'regenerative vs. de-generative" ?

Dumb question what would be the "Normal" hoops one would have to jump through with Mazak to obtain such a part number (especially on this vintage of machine) ?

Since that is a Mitsubishi drive, the first step would be to not call Mazak and go through Mitsubishi.

@OP, I have a bit of documentation on the MDS-A spindle drives at my shop. I do not recall it getting detailed enough to list the specific part numbers for transistor modules, but I'll have a look later today.

Sorry, I only have troubleshooting, set up, and integration info. No spare parts numbers.

You may be able to find it here....

Thank you all for your quick replies! And very sorry for the confusion.

Yes, I'm looking for a power transistor. The other three in the power unit have part number PM200DKA060 . They have P and N outputs, 5 pins both. The regeneration transistor has N output, 5 pins.

It could be IGBT...
