Category: Alarm

Cause

1. Supply voltage exceeds the permitted range, AC280V;
2. Braking resistor open circuit or mismatch prevents absorption of regenerative energy;
3. Load inertia exceeds the permitted range;
4. Drive damaged

Corrective action

1. Apply voltage within the correct range;
2. Check whether an external resistor is connected. Measure its resistance to determine whether it is open-circuited, and ensure correct wiring. If the resistor has burned out, replacement with a higher-power external resistor is recommended (contact the manufacturer for advice);
3. Increase acceleration/deceleration time or select an appropriate drive and motor again according to the load inertia
