Tips: The difference between soft starter and variable frequency drive (VFD)
From the application, the soft starter and variable frequency drive (VFD) are two completely different products. The soft starter is actually a device that controls the voltage and limits the starting current, uses for starting motor and only changes the output voltage amplitude without changing the frequency. And VFD is used for the device needed speed governing, the output not only changes the voltage but also changes the frequency. From the function, VFD has all the functions of the soft starter, so it can be said that VFD is a more powerful soft starter.
Although the soft starter solves the problem of motor starting, but there is no significant energy saving effect. When start using energy-saving operation mode, no-load energy saving is 40%, and load energy saving is only 5%. VFD not only solves the big impact current caused by the motor starting, but also has the good energy saving effect and the frequency conversion ability.

Soft Starter Works with a Bypass Contactor

Soft starter works with a bypass contactor saving energy by eliminating thyristor losses during the run. The bypass contactor shunts the current flowing through the soft starter switch circuit to reduce heat accumulation in the soft starter power electronics during motor operation. This provides maximum efficiency and prolongs the life of soft-start switching components because they only work during the start and stop cycles of the motor.

Soft Starter Bypass Output Failure: How to Continue Motor Operation

In this video, you are shown how to use an AC contactor in conjunction with a soft starter as a backup solution to start a motor when the soft starter's bypass output is not operational. The strategic combination of a soft starter and an external bypass contactor provides a fail-safe mechanism for motor starting and operation, especially when faced with challenges with the soft starter bypass output.

Is there anything I can try in the settings to give it a better chance?

I did try it last night with all the default settings. It started to turn the motor for about 5 seconds but then my generator quits and says under voltage and under frequency on my generator panel. It is so close to working. Is there anything I can try in the settings to give it a better chance?
