Our 1993 HAAS VF-2 Magnetek variable frequency Spindle Drive Controller has failed.
The failure appears to be a 220 mfd 35 V electrolytic capacitor that appears to have shorted and overheated enough to burn the pc board. However, the capacitor does not show a short with a Fluke ohmmeter. It was a capacitor failure even though it does not show a short at low voltage.
We have ordered a rebuilt unit, and I will report on how it works. The rebuilt unit includes all new electrolytic capacitors. This unit does not come from HAAS, their price is way too high. It should be noted that there may be a number of different controls that could be used in place of the Magnetek. However, the Magnetek is reported to be a very reliable unit.
