1: ERROR: over voltage fault in KEB COMBIVERT R6 Drive indicates the DC bus voltage is dangerously high. This means the internal DC bus exceeded 900VDC, typically caused by excessive regenerative energy from the motor or line spikes.
Cause:
Over Voltage; DC bus voltage is too high (> 900VDC).
Remedy:
Ensure braking resistor or regen unit is properly operating and connected.
