500 HP motor trips out at the soft start with no rhyme or reason. POCO serves the mill with a 2500kVA pad, 480Y/277 to an 800 amp main. That panel has a breaker feeding an AB soft start. When the soft start does trip out, the only way to get it back on is to kill the circuit and wait 15 minutes.

The best way to start a high inertia load is to set the starter up for a current limit only. There is nothing gained from a current ramp on a high inertia load. The acceleration time is determined by the start torque (controlled by the start current) and the load inertia. Try to start with the current limit set at 400% and see how long it takes ...
