Ground Fault Interrupter Activates When Drive is Running
Cause Possible Solutions
The output of the drive is a series of high frequency
pulses (PWM), so there is a certain amount of leakage
current. This may cause the ground fault interrupter
to operate and cut off the drive input power.
• Change to a ground fault interrupter with a higher leakage current detection level (such as,
a sensitivity current of 200 mA or greater per Unit, with an operating time of 0.1 s or more),
or one that incorporates high-frequency corrective actions.
• Change the Carrier Frequency Selection (C6-02) to lower the carrier frequency.
Note: Leakage current increases in proportion to cable length.
