Why does Huainan Wan Tai 30 magnetic starter have two stopping points?

The voltage is unstable and the control program is inaccurate.

1. voltage instability: the soft starter has been started, and the load mechanism cannot work normally due to voltage instability, so it stops working.

2. Inaccurate control program: As the control program of the soft starter is set inaccurately, the load mechanism cannot be effectively coupled with the soft starter.
