Category: Alarm

Cause

1. Command input simultaneous with servo activation or command input too fast
2. External braking resistor too small or short-circuited
3. Poor motor cable contact
4. Motor cable grounded
5. Motor UVW cable short circuit
6. Motor burned out;
7. Software detected power transistor overcurrent

Corrective action

1. Check command input timing; input commands after the servo turns on rdy;
2. Measure whether the braking resistor resistance meets specifications and select an appropriate resistor according to the manual;
3. Check whether cable connectors are loose and ensure that they are secure;
4. Check insulation resistance between the motor UVW wires and motor grounding wire; replace the motor if insulation is poor;
5. Check the motor UVW cable connection for short circuits and connect the motor cable correctly;
6. Check whether resistance between each pair of motor cables is equal; replace the motor if not;
7. Reduce the load. Increase drive and motor capacity, and increase acceleration/deceleration time
