Vdc-max controller de-activated

What does A00910 mean?

The DC-link maximum voltage controller has been deactivated. This typically happens if the main supply voltage is consistently too high, if the motor is regenerating power back to the drive due to an active load, or during deceleration with high inertial loads. This can lead to excessive DC link voltage and potential damage to the drive components if not managed.

Complete Troubleshooting Guide

1. 1

   Verify that the input mains supply voltage (P0210) is within the acceptable operating range for the drive.

2. 2

   Ensure that the motor and load are appropriately matched to prevent excessive regenerative energy.

3. 3

   For high inertial loads or frequent deceleration, consider installing or verifying the functionality of a braking resistor to dissipate excess energy.
