Earth fault protection ensures that the sum of the motor phase currents is zero. The
overcurrent protection is always working and protects the AC drive from earth faults with
high currents.

Deactivating the protection, i.e. setting parameter to 0, will reset the thermal stage of the
motor to 0%. See Chapter 8.4 Parameters of motor thermal protection (IDs 704 to 708).
Motor overtemperature sensing is required if the parameter is set to 0.
705 MOTOR THERMAL PROTECTION: MOTOR AMBIENT TEMP. FACTOR 234567 (2.7.9)
The factor can be set between -100.0%...100.0% where
-100.0 % = 0 °C
0.0 % = 40 °C
100.0 % = 80 °C
See Chapter 8.4 Parameters of motor thermal protection (IDs 704 to 708).
