Delay when
rope-tracking
frequency
reached
enabled, if the set frequency is lower than the
rope tracking frequency, the VFD boosts to the
rope tracking frequency after startup and takes a
delay later. When the delay is reached, the VFD
calculates the output torque. If the output
frequency is greater than the preset torque
(empty-load torque usually), the VFD considers
the rope is too tight. Then the frequency is
decreased to the set frequency.
