After Factory Reset of P051=21, Found Field current was not developing to the set point even though all settings were done correctly as per the start-up procedure. Motor field current is 0.56 A. But current was going to 1.6A when measured through clamp meter. After optimization of p051=25, field current went to 0.1 A and filed voltage was only 5V. Could not do any improvement even adjusting the field firing angle. It was noticed that actual field current was showing 120%. Field card was changed and no improvement was found. So P051 = 22 (Field Off set value) was done once. Found field has developed to the set point and working ok Pradeepkumar Salem Steel Plant ------------------------------------------------------------------------------------------ |
