Description
The actual current limit setting is too high
relative to the selected constant control fre-
quency level. Reduce the control frequency
setting or reduce the current limit setting.
A high-impedance ground fault is detected
on the output. Check the insulation of motor
cable and motor.
A high-impedance ground fault is detected
on the output. Check the insulation of motor
cable and motor.
A low-impedance ground fault is detected on
the output. Check the insulation of motor ca-
ble and motor.
A high or low-impedance ground fault is de-
tected on the output. Check the insulation of
motor cable and motor.
A short circuit at the inverter output is de-
tected. Check the motor and motor cable.
A critical output overcurrent has been de-
tected. Check for short circuits on the output.
The gate driver has detected desaturation
condition.
A current imbalance between paralleled
power units has been detected.
The motor is disconnected.
A missing motor phase is detected. Check
motor, motor cables, and connections.
Excessive spikes on the grid voltage have
been detected.
Grid voltage (RMS) above the normal operat-
ing range is detected.
A grid voltage (RMS) below the normal oper-
ating range is detected.
