Frequency Determines how the Drive will
Reference react when the frequency
Loss reference is lost. The frequency
Detection reference is considered lost
Selection when reference drops 90% or
more of its current value for
400ms.
0: Stop - Drive will stop.
1: Run at L4-06 PrevRef -
Ref Loss
Drive will run at the
Sel
percentage set in L4-06 of the
frequency reference level at
the time frequency reference
was lost.
