I'm having issues with a Baldor ( ZD18H220Y/D 15H 10K rpm) on my 1996 6030 Fadal. I suspect it is related to a low speed issue. The spindle will run and stop as normal, but I can't get the spindle to turn slower than 225 rpm. I first noticed the issue when it would not index for a tool change. I can see the lights on the controller alternating between fwd and rev while trying to index the spindle for a tool change, but the spindle doesn't move. Eventually it gives up and shows "Orientation Failure". I did replace the encoder on the motor and it didn't make a difference. I also tested the hall effect switch and it is working also. Any ideas?
Thanks
