Error Code E-07 on 2 HP Single to Three Phase VFD

Hello everyone!
I'm using an ATO 2 HP single-phase to three-phase VFD (GK3000-2S0015) and encountered an Error Code: E-07. According to the manual, this error indicates an input power issue. Does anyone have additional insights or suggestions on how to troubleshoot this?

Hi, Edward, the VFD show an Error Code: E-07 may be caused by the high input voltage. The normal input voltage of the VFD should be 220VAC±10%. Please use a multimeter to measure the input voltage of the VFD and check what the highest input voltage is.

Thank you for your response. I measured the input voltage to the VFD, which is 213.8 VAC.
When testing the drive without a load, it operates normally. However, when a load is connected, the drive experiences issues.
Do you have any insights on this?

You can set the acceleration and deceleration time of VFD as P0.17=10 or 12, P0.18=10 or 12, and test again.
If the VFD still cannot start normally after connecting the load, please check carefully whether the insulation of your load motor is damaged and there is leakage to the ground. You can use a megger to test if your motor insulation is working properly. Or you can replace another motor to test if possible.
