Hi Hood, I think so but will check later today, when you say isolated do you mean not in contact with any metal parts connected to the mill or earthed? Sorry mate not very clear on electrical terms. I have noticed the 0v and 10v control wires are close to a doughnut transformer and was wondering if this was the problem as when I turn on the machine the spindle has a surge up to 1000 revs for a split second. The spindle then behaves itself for 10min then starts to slowly rotate at say 100 revs for the rest of the day.
