7.5kW VFD E-01 Overcurrent Error on Startup

I’m working on an ATO GK3000 220V 7.5kW VFD that was installed last summer. This month, when I first turned the power on, the drive started right up with no issues. However, this morning when I tried to start the pump, the drive began its windup but then shut down with an E-01 error.
Last year, I was told that when this happens, I should shut off the main power and wait about a minute to let it reset. I did that, but now the pump doesn’t turn on. The drive display just flashes “60.0” on and off.
Is there a way to fully reset the drive so I can get my pump running again? Any advice is appreciated.

Suggestions:
1. Check whether the pump load is stuck or difficult to start.
2. Try extending the acceleration time in the parameters to reduce inrush current during startup.
