Hello all need some help. I have a CNC machine that uses 5 Ultra 3000 servo drives. The X axis drive goes into a E21 fault sporatically.
Occasionally 2 other axis also get an E21 error.
We have replaced the Drive, Encoder Cable, and Servo Motor. The error still exist. It refers to the Auxiliary encoder, but I am not sure what this is. There is the main encoder incorporated in the servo motor, but what is the auxiliary encoder?
Anyone fought the E21 error before and succeeded?
