Found a problem with load and unloading vales. In the star circuit, the rotation of the motor was slow enough to change to a deltar circuit. The current rose abnormally high.
Discovered issues with loading and unloading valves<br>When the star cycle occurs, the rotation cycle of the motor is slow enough to switch to the star cycle. The current is abnormally high.
Found the problem of loading and unloading valves.<br>When the star circuit is used, the rotation period of the motor is slow enough, and the conversion circuit is a deltar circuit, and the current is abnormally high.
