I am in need of help. I have an old FANUC robot M710i with RJ2 Controller. I recently had to remove and disassemble a motor to replace the axis bearings. The problem is the motor won't start after I put it back in. It get's powered up, I can hear the brake released but no motion from the axis. After 2-3 seconds OVC alarm hits. Sometimes it turns but the motion is jerky, bumpy. Is it a pulsecoder issue ? In situations like this that I have to remove a motor for bearing service is there a procedure I must follow when I assemble and disassemble the pulsecoder from the motor ? Can I directly enter the pulsecoder data of the serviced motor that was stored from the last MASTERING in DMR GROUP sys variable ? Should I mark the pulsecoder position somehow and position the axis there during assemble procedure ?
I always put the robot in zero degree position when I service or replace a servo motor.
