Note:
(1) Long motor cables (with more than 100 meters) will have a high leakage capacitance to the ground. The
circulation of leakage currents through these capacitances may activate the ground fault protection after
the inverter is enabled, and consequently, the occurrence of fault F074.
POSSIBLE SOLUTION:
- Decrease the carrier frequency (P0297).
(2) In case of F030 (Arm U Fault), F034 (Arm V Fault) and F038 (Arm W Fault) faults, there is an indication at
the IPS1 board that signalizes which of the power units is presenting the fault. The indication is done through
LEDs that remain on when the fault occurs. When a reset is performed, the LED that indicates the fault goes
off (refer to the figure 0.1).
