A soft start is a starter that bring a motor from the starting point of a slow speed in to a multiple speed that can be programmed in the starter
Imagine you have a big plant in your factory, the voltage will go down/up when the plant start/stop, cause the sharp start/stop
The soft starter is controlling AC motor in soft start/stop to eliminate such problems.

I assume a 3 phase, AC induction motor. A star delta starter or a soft starter can be used. A soft starter is better compared to a star delta starter, but it is more expensive.
An inverter is just a device to invert one form of electrical power supplied to its input into another form of electrical power as its output. A soft starter may be included into an inverter design, its function is just to provide temporary power to the inverter until it gets started. After that the soft starter is disabled, usually by a diode feedback link.
Check the earth fault trip off set limit of the ACB. It may be too low.
The starter motor is at the rear of the engine.
in 4 point starter we use a protactive rasistance to control the speed of motar in 3point starter speed is uncontolled
nothing
nothing
DOL, Star Delta, Soft starter, VFD
Most of the motors are usually controlled by the soft starters which usually trip frequently. One of the steps in find why the soft starter has tripped is looking at the motor circuit protector rating.
It is an advanced power electronic device to start the motor with a very smooth starting curve. It is next generation starter compared to DOL or star Delta starter

You could cheat or soft reset.

it could go on and on. have to be lucky
You can by soft resetting a numerous amount of times.
Probably. More importantly, why would you want to? The Star/Delta starting method is used to minimize motor starting current, just like a soft starter. Use one or the other. There's no good reason to use both, it will just make things more complicated.
