DC link voltage too high

What does 07 mean?

The DC link voltage has exceeded its permissible limit. Potential causes include a ramp time set too short, incorrect wiring or internal resistance of the brake coil/braking resistor, thermal overload in the braking resistor, or an invalid mains voltage range. High DC link voltage poses a risk to the inverter's components.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Check the internal resistance of the brake coil/braking resistor, referring to the "Technical Data" section of the manual for expected values.

2. 4

   Check the mains voltage to ensure it is within the valid operating voltage range for the unit.

3. 5

   Reset the fault by switching off the DC 24 V supply voltage.
