Problem "Electric soft starter"

Featured Replies

A soft starter is only operational during starting of the motor. Once up to speed it is bypassed (unlike a VSD which continuously powers the motor)

And if there is an issue, like over-current, or the motor fails to get up to speed within the time limit, it will shut down. They usually also have to get configured for the motor you want to start. Without knowing more, there is no way of knowing what is wrong.
