Hi
I am using a Chinese servo motor DORNA 130DNMA2-01D5CKAM (1.5kW, 2000rpm, 7.16Nm) with its compatible EPS-B1 series drive to feed metallic strip into a press machine. The servo is coupled thru a spider coupler to a set of metallic rollers which feed a predefined length.
The servo works fine except that after POSITIONing movement, sometimes the motor does not come to halt. The shaft would move 1 step clockwise and then 1 step anti-clockwise (repeatedly). This wrong positioning (+/- 1-2 millimeters) is disturbing further processing.
After some serious googling, I learnt that I need PID tuning for my system. I need some guidance how to do it.
