Spindle only spins in reverse (1988 Triac)
Posted: Tue 22 Aug , 2006 10:20 am
Hi All
I have a old 1988 Triac pnc3. My problem is the spindle will only spin in reverse!
You select forwards, give it a speed and enter. Then relay 3 (spindle reverse) energises, followed by the relay on the spindle control board, and the spindle starts to turn, in reverse!
It will now only spin in reverse although I have had it spinning forward.
Its the North east electronics board with the Brown & Prestal spindle control. 3 Phase motor.
Does anyone have any experience of the problem or any suggestions?
