065

[Reactive I Ref]
If selected by [Reactive I Sel], this parameter sets the reference for the reactive current. This can be
used for power factor correction of the power system. Positive value gives inductive current; negative
value gives capacitive current. The maximum reactive current is limited by the following formula:

Default:
