Dear friends,
I have a problem in our haas spındle regen rezistor driving.
When high voltage contactor goes to active, regen rezistor driver Mosfet marked IXYS 75N120 is defected.
Its price is about 75 USD,in other words too expensive, for this reason I am afraid to test new one.
Can somebody help me?
At least can somebody tell me how it works?
In which conditions or working phase the Mosfet is in circuit,active?
Mosfet driver Ic is A316J

Note: I have Vector Drive circuit drawings, I have plotted them. If a friend needs them, do not hesitate to write me...

Best regards
Tayfun Kusluoglu
