Fault means that the connected drives must be brought to a stop immediately.
Causes:
§ Excessive temperature in the rectifier
§ Overvoltage
§ Short-circuit in the brake chopper path
§ Grid
§ Activation in the short-circuited DC link
Relay and LED state display
The relay and LEDs always display the same state. The states are displayed using the priority
list initialization/ready < Warning 1 < Warning 2 < Fault. The display of states with higher priority
replaces the display of states with lower priority (example: warning 2 overwrites warning 1).
States with a lower priority are only displayed after the higher prioritized state has been
displayed for at least 4s.
LEDs:
Green/Red/
Yellow
