"Hold precharge" operating mode (ModePrecharge)

The "Hold precharge" operating mode (ModePrecharge) is used to control the internal "Hold precharge" firmware function (FCB 53).

The DC link is still precharged, the line contactor is controlled. However the output stage is inhibited, i.e. active operation is not possible.

More information can be found in the device manual, especially with regard to the function of FCB 53.
