Problems caused by incomplete power failure [Copy link]

When the inverter was powered on for the first time, it reported a fault as soon as it started because the acceleration time was not adjusted properly. The power was not completely off, but a black screen was displayed and it was powered on again. However, after the parameters were adjusted to a reasonable range, the fault occurred again when it was started again. This time, it was finally possible to wait until the power was completely discharged and then it was powered on again and there was no problem. I want to find a reasonable explanation?

When the inverter was powered on for the first time, the acceleration time was not adjusted properly, causing a fault, power failure, and restart. The fault occurred again after powering on again.

Are you kidding?

When you buy a TV, you don't just need to read the manual in detail. You should also take a look at the precautions for starting it up.

The inverter was powered on for the first time, but the parameters were not adjusted properly, which caused the failure. I still can't figure it out.

Bought a second-hand inverter?

There are many parameters to set when starting the inverter, but each parameter has a certain selection range and must be set within the range.
If a parameter does not work properly, such as the control mode and carrier frequency If
the acceleration time is not adjusted properly, the startup alarm will be reported, so that the black screen will not be continuously reported.
