POWER PICKUP DELAY
Range: 0.000 to 6000.000 s in steps of 0.001 s
Default: 0.200 s
The setting defines a definite time delay before the inverse time characteristic is
activated. If the curve selection is set as “Definite Time” the element operates after this
security time delay. If the curve selection is “Inverse,” or one of the FlexCurves, the
element uses both the definite and inverse time timers simultaneously. The definite time
timer specified by this setting, is used, and when it expires it releases the inverse time
timer for operation (torque control).
