Centroid Alarm 437 Servo power removed
Cause & Effect
Axis was moving more than 300 RPM while power was supposed to be off.
1.) Motor may be wired backwards.
2.) May be a shorted servo drive.
3.) Axis motion is canceled but
motor continues to move due to inertia, which is probably caused by an unbalanced axis. Power to motors is released.
Action
Check motor wiring, servo drive, or look at Kg value in PID and make sure it’s not above +/- 5.
