Function
The monitoring indicates a message if the DC bus voltage (terminals + U
G
and -U
G
) exceeds the
threshold (switch-off threshold OU) set under C0173.
The message is reset if the voltage falls below the switch-off threshold OU again.
The table above shows the setting of the switching thresholds according to the selection number.
The switch-off threshold OU determines the voltage level of the DC bus voltage, where the pulse
inhibit is activated.
The selection number is also effective for the low voltage monitoring (LU).
