SoftPLC
(1) Very long motor cables (longer than 100 meters) present a high parasite capacitance against the ground. The circulation of parasite currents
through those capacitances may cause the ground fault circuit activation and thus disabling the inverter with F074, immediately after the inverter
enabling. Possible solutions:
- Decrease the carrier frequency (P0297).
- Install an output reactor between the inverter and the motor.
(2) With a Profibus DB module connected into the slot 3 (XC43).
(3) With IOE-01 (02 or 03) modules connected into the slot 1 (XC41).
(4) All the models with a SoftPLC applicative.
