I have a 3RW406-1AB14 soft starter running a 460V, 40 hp, 50 FLA motor on a water pump. I am recording current spikes of 120 amps on ramp down on phase B & 70 amps on phase A & C! There are actually three pumps all with the same soft starter & they are all doing the same thing. The ramp up is set to 2 sec, starting voltage to 40% & ramp down to 20 sec. I would like to know why I am seeing such a high current spike on only phase B & also why such current spikes on ramp down? ------------------------------------------------------------------------------------------ |
