Description, Explanations
Enable / Disable function
Max. voltage dip duration time before a trip is signalled.
If the voltage dip ends within this time window an autorestart is
triggered (if enabled).
Delay until the motor is restarted
Enables the autorestart of the motor after end of the voltage dip
Voltage level indicating the end of the low voltage situation
Voltage level indicating a low voltage situation and triggering the
DIP logic.
Above this ground fault current a ground fault tip is triggered.
A value of 255 % disables the trip.
Delay time until a ground fault trip is triggered.
Trip happens after the configured delay time plus a internal
calculation time of about 600ms.
Above this ground fault current a ground fault warning is
triggered.
A value of 255% disables the warning.
Delay time until a ground fault warning is triggered.
Warning happens after the configured delay time plus a internal
calculation time of about 600ms.
Mode of internal ground fault protection: Defines when the
internal ground fault protection is active.
