A13

Alarm code A13 indicates .

Cause analysis:

1. Insufficient drive energy dissipation capacity causes increased regenerative energy and a rise in bus voltage; A13, A15, and A16 may all occur;

2. A supply voltage problem;

3. A drive problem.

Remedy:

1. Measure whether the resistance of the braking resistor connected between the drive's B1B2 terminals is normal (see the electrical drawings for specific data). If the resistance is too high or too low, the braking resistor is damaged;

2. Measure whether the supply voltage is within the normal range;

3. Confirm by swapping drives.
