DC link voltage too high

What does 07 mean?

This fault occurs when the DC link voltage exceeds its safe operating limits. This condition can be caused by regeneration from the motor, short ramp times, or issues with the braking resistor configuration.

• Ramp time set too short, leading to excessive regeneration.
• Faulty connection between the brake coil and braking resistor.
• Incorrect internal resistance of the brake coil/braking resistor.
• Thermal overload in the braking resistor due to incorrect sizing for the application.

Click steps to track your progress.

1. 1

   Increase the ramp time setting.

2. 2

   Check the connection between the braking resistor and brake coil for integrity.

3. 3

   Check the internal resistance of the brake coil/braking resistor (refer to the "Technical Data" section of the manual).

4. 4

   Verify the braking resistor size is appropriate for the application's energy requirements.

5. 5

   Switch off the 24 VDC supply voltage to reset the fault.

6. 6

   Issue a reset command via MOVILINK®.
