Function
The monitoring will be activated if the DC-bus voltage (terminals +U
G
and -U
G
) falls below the
threshold (switch-off threshold OU) which has been set under code C0173.
The message will be reset when the value falls below the switch-on threshold OU.
Thetableaboveshows thesettings for the switching thresholds according to the selectionnumbers.
The switch-off threshold OU determines the voltage level of the DC-bus voltage at which the pulse
will be inhibited.
The selection number also applies to the undervoltage monitoring (LU).
