Section L: Protection Parameters

L8 Hardware Protection

The output phase loss detection circuit monitors the DCCT and activates when one of the output

phases are lost. The detection circuit calculates the RMS current value (I

RMS

) for each of the phases

and compares it with an internal output detection level. If I

RMS

decreases to or below the detection level

for 10 seconds, an output phase loss (LF) fault occurs, and the motor coasts to stop.

The ground fault detection circuit monitors the output current and activates when one of the output

phases is connected to ground.

A ground fault will occur when the inverter output grounding current has exceeded 50% of the inverter

rated current.

When a ground fault condition occurs, the following fault code will be displayed: “GF Ground Fault”.
