I have a spindle drive on my 97 Haas VF-2 that may be bad, it's a Magnetek GPD 515. I have the manual and it says to check the bus voltage at display U1-07, but I can't seem to get to that display. I found U1-01 thru U1-06 but then it goes to some other place rather than U1-07. I need to check the voltage before sending out for repair.
Thanks is advance-----Mike
Found the terminals on the drive unit. (4 and 5 from the left) Voltage is good, so off for repair.

I sent my unit to Zaritron, LLC on Monday and had it back and installed on the machine by Thursday afternoon. Highly recommend Zaritron, LLC in Illinois.
Thanks---Mike
Thanks for the source. I assume this was to fix a 123 alarm? Issues during spindle accel or decel? Or something else?Quote:
