The high voltage is the problem of the power supply, which cannot be controlled, and the voltage of 410V is the normal range. If the occurrence of 410V voltage is to show fault shutdown, there are only two ways to deal with it:
1. Modify the protection voltage parameters of the controller;
2, let the manufacturer installed in the power distribution room adjust the voltage.
Strictly speaking, this is not a fault, which belongs to the unreasonable setting of protection parameters.
Also, about not being able to stop the plane. There are many situations in which the machine cannot be stopped, but usually the most common is that the AC contactor is burned and bonded, and cannot be reset, first check this. The method is very simple, as long as you see that in the state of no boot, the AC contactor has no reset, and the AC contactor that will not be reset is replaced. If the AC contactor is normal, it is necessary to consider whether the stop button of the control panel is faulty, and the frequency converter is faulty. The troubleshooting method of these two things is more complex, and it is not possible to describe them in words. It is recommended that suppliers or manufacturers repair them.
