I am at home, with no reference books and a friend has asked about a problem he currently has on site.
He is working on a machine with a Fanuc A06B-6088-H222 spindle drive with "--" in it's dispaly.
Am I correct in saying that the drive is not enabled, and that the drive's internal relay has not energised via a voltage that should be applied to the drives enabling terminals? (Pins 3 & 4 at 100Vac?)
And if 100Vac is applied, then the internal relay may be faulty?
Or am getting confused with another drive system?
