PSE250-600-70 issue the ampere cannot ramp up during starting.
The softstarter have been used for 6 months for crushing lime stone application, but recently found when starting the ampere cannot reach to 900A+; it only stay at 380 to 400 ampere like that. The user mention the error only came up later showing P1. Could this be the internal thyristor fault? As setting is follow the default. Motor is 90kW which is smaller than the Softstarter. Appreciate if can advise based on experience. Thanks.
