Hi all,
I have been getting a 414 x axis detect error alarm on my Yang ML25 lathe becoming more frequent over the last few months. When it happens it goes to a 'not ready' state and no alarm shows on the drive board. Diagnostic 720 shows an overcurrent state. It only happens in rapid travel on 100%, not 25 or 50%. I have replaced the X axis bearings as they were getting a little noisy but this made no difference. I have now replaced the motor, encoder and drive board which has made no difference. The brake is working as it should and I've tested all the cabling and no faults are showing. Yesterday I stripped the bearings back out and checked them as well as the ball screw. Everything is working smoothly with no tight spots.
I really am at a loss as to what to try next as I am running out of parts to change!
I wondered if anyone else had seen this fault and found a solution before I resort to calling Fanuc out to take a look ££££!
