DC link voltage too high

Hva betyr 07 ?

The DC link voltage has exceeded its permitted threshold. This condition often arises from regenerative braking if the ramp time is too short, issues with the braking resistor/coil, or an invalid supply input voltage.

• Ramp time set too short, leading to excessive regenerative energy
• Faulty connection between brake coil and braking resistor
• Incorrect internal resistance of brake coil or braking resistor
• Thermal overload in the braking resistor due to incorrect sizing for the application
• Invalid supply input voltage range

1. 1

   Increase the ramp time setting

2. 2

   Check the connection between the braking resistor and brake coil and correct if necessary

3. 3

   Check the internal resistance of the brake coil and braking resistor (refer to 'Technical Data' section)

4. 4

   Check the supply input voltage for valid voltage range

5. 5

   Reset the error by switching off the DC 24 V supply voltage

6. 6

   Reset the error via the control system or dedicated reset function
