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.
