±5 Hz
Selects the soft starter's tolerance for frequency variation.
CAUTION
Running a motor outside its specified frequency for long periods can cause damage and premature failure.

100mA
Sets the trip point for ground fault protection.
The Digistart IS can be configured to trip if ground fault exceeds a specified level while the motor is running. Ground fault is a
dynamic trip based on phase current measurements every half-cycle.
NOTE
Ground fault protection is only available if the RTD/PT100 and ground fault protection card is fitted.

Motor Temperature Check
Do Not Check, Check
Do Not Check
Selects whether the Digistart IS will verify the motor has sufficient thermal capacity for a successful start. The soft starter compares
the motor's calculated temperature with the temperature rise from the last motor start and only operates if the motor is cool enough
to start successfully.
8.8.7 Group 6 - Protection delays
Protection delays slows the Digistart IS's response to the trip condition, avoiding trips due to momentary fluctuations.
