6. Troubleshooting

1, the status on light’s indication

RUN: green, normal work light.

ERR: red, failure light, the motor with phase short-circuit, overvoltage and under-voltage

protection.

2 Troubles

Causes

Measures

LED off turn

Wrong connection for power

Check wiring of power

Low-voltages for power

Enlarge voltage of power

Motor doesn’t run, without

holding torque

Wrong connection of stepper

motor

Correct its wiring
