H7 ASD Operation Manual 101Run FrequencyProgram ⇒ Special Control Parameters ⇒ Frequency ControlThis parameter establishes a center frequency (Run Frequency) of a frequencyband .Parameter F242 provides a plus-or-minus value for the Run Frequency; thus,establishing a frequency band.During acceleration, the drive will not output a signal to the motor until thelower level of the band is reached.During deceleration, the drive will continue to output the programmeddeceleration output signal to the motor until the lower level of the band isreached; at which time the output will go to 0.0 Hz.Direct Access Number — F241Parameter Type — NumericalFactory Default — 0.0Changeable During Run — YesMinimum — 0.0Maximum — Max. Freq. (F011)Units — HzRun Frequency HysteresisProgram ⇒ Special Control Parameters ⇒ Frequency ControlThis parameter provides a plus-or-minus value for the Run Frequency setting(F241).Direct Access Number — F242Parameter Type — NumericalFactory Default — 0.0Changeable During Run — YesMinimum — 0.0Maximum — 30.0Units — HzEnd FrequencyProgram ⇒ Special Control Parameters ⇒ Frequency ControlThis parameter sets the lowest frequency that the drive will recognize duringdeceleration before the drive goes to 0.0 Hz.Direct Access Number — F243Parameter Type — NumericalFactory Default — 0.0Changeable During Run — YesMinimum — 0.0Maximum — 30.0Units — Hz0 Hz Dead Band SignalProgram ⇒ Special Control Parameters ⇒ Special Parameters ⇒ DeadBand of 0 Hz FrequencyThis parameter sets an output frequency threshold that, until the commandedfrequency surpasses this setting, the ASD will output 0 Hz to the motor.Note: This setting will override the Startup Frequency setting (F240) if thissetting has a higher value.Direct Access Number — F244Parameter Type — NumericalFactory Default — 0.0Changeable During Run — YesMinimum — 0.0Maximum — 5.0Units — HzF241 F244www .
