The soft starter I'm using is a Siemens, it has a settings for maximum starting current and overload current. The motor nameplate FLA is 122 amps. The motor bogs and does not reach synchronous speed until I have raised the starting current to 425 amps. This equals 3.5 times the nameplate current. I have never had to set the starting current this high, in the past lowering the starting current just prolonged the time it took to get to speed. My three phase voltage dips from 205 VAC to 191 VAC. Does anyone know what could cause this high starting current with a soft starter? (This motor is being used in a hydraulic elevator pump unit.)
