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.
