BMC 20 Ultimax 3.
Over the past year or two I've been getting several different errors with this machine that stop it running. These have been:
Magazine reference limit switch not seen.
ATC. Error. magazine is not in position.
Encoder fault on axis S.
Servo drive fault on axis S.
Servo drive fault on axis Y.
It throws up a different one of these most times but will run fine for a period of time in between. The ATC errors can be sorted by rotating the carousel in diagnostics. The servo drive and encoder errors need a reboot to clear but it's fine afterwards. However the latest one, Servo drive fault on axis Y seems to be there for good this time.
This is what I can't understand. The machine will switch on and calibrate no problem. I can also do a warm up and feed/rapid the table around ok. If I go to start the spindle at anything above 2000 RPM though it trips out and throws up the error Servo drive fault on axis Y. There can't be anything wrong with axis Y as it moves about perfectly ok.
If I go to run a program it will select the tool and rapid to the start position. Then it starts the spindle and straight away trips out as the revs build up. I can set the manual spindle speed to 2500 RPM, turn the override right down and then start the spindle in manual but as I slowly turn up the override it gets almost to 3000 RPM and then trips out with the warning Servo drive fault on axis Y.
I'm going to ring the service department on Monday morning but has anyone on here any ideas what it could be.
