If overcurrent, oL1, or oL2 occur during overexcitation deceleration, reduce the overslip suppression current level. Set as a

Reduce this setting if the current during overexcitation deceleration exceeds the overslip suppression current set in n3-21 as
a result of flux saturation and excessive slip. Alternatively reduce the overexcitation gain n3-13.
