Description
In drive module arg, the DC bus voltage inside the rectifier unit at drive unit position arg reaches the limit value for closing the 24 mains and 24V brakes.
Consequences
The system cannot operate until the fault is corrected, and the system will enter the "system interruption" (SYS HALT) state.
Possible causes
This error code is usually the result of relaxing the grid for an extended period of time.
Recommended actions
Verify that the grid voltage is high enough. Verify that the grid is connected correctly and that the fuse is not blown. Verify that the grid inductance is not too high, causing the grid to be weak.
