Why does YASKAWA CIPR-GA50C show Ground Fault?
- SsnyderjacobNov 21, 2025
If you're experiencing a ground fault with your YASKAWA Controller, here are a few things to check: 1. Motor Issues: * Overheating may have damaged the motor, or the motor insulation may be inadequate. Measure the motor insulation resistance and replace the motor if there's electrical conduction or unserviceable insulation. 2. Cable Problems: * The motor's main circuit cable might be short-circuiting against the ground. Examine the cable for damage and repair any shorts. Measure the resistance between the cable and the ground terminal; replace the cable if there's electrical conduction. 3. Stray Capacitance: * Increased stray capacitance between the cable and ground can cause leakage current. If the wiring length exceeds 100m, try decreasing the carrier frequency and ...
