Can one soft starter control multiple motors for parallel starting?
Yes. The circuit configuration and soft starter selection depends on the application.
- Each motor must have its own overload protection.
- If the motors are the same size and are mechanically coupled, a constant current soft starter can be used.
- If the motors are different sizes and/or the loads are not mechanically interlocked, a soft starter with a timed voltage ramp (TVR) start profile should be used.
- The combined motor FLCs must not exceed the soft starter FLC.
