FCB 53 Hold precharge
If you activate this FCB, the DC link will be precharged and the line contactor will be closed. The DC link voltage is not controlled, no ready signal is sent to the connected axes, and the output stage is inhibited. If you switch between FCB 58 and FCB 53 during standard inverter operation, the output stage is inhibited.
Priority of FCB 53: 3
