118 HX7+ ASD Installation and Operation Manual
Run Frequency
Program Special Control Frequency Control
This parameter establishes a center frequency (Run Frequency) of a frequency
band.
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 the
lower level of the band is reached.
During deceleration, the drive will continue to output the programmed
deceleration output signal to the motor until the lower level of the band is
reached; at which time the output will go to 0.0 Hz.
Direct Access Number — F241

Run Frequency Hysteresis
Program Special Control Frequency Control
This parameter provides a plus-or-minus value for the Run Frequency setting
(
F241).
Direct Access Number — F242
Parameter Type — Numerical
Factory Default — 0.0
Changeable During Run — Ye s
Minimum — 0.0

Units — Hz
End Frequency
Program Special Control Frequency Control
This parameter sets the lowest frequency that the drive will recognize during
deceleration before the drive goes to 0.0 Hz.
Direct Access Number — F243
Parameter Type — Numerical
Factory Default — 0.0
Changeable During Run — Ye s
Minimum — 0.0
Maximum — 30.0
Units — Hz
0 Hz Dead Band Signal
Program Special Control Special Parameters
This parameter sets an output frequency threshold that, until the commanded
frequency surpasses this setting, the ASD will output 0 Hz to the motor.
Note: This setting will override the Startup Frequency setting (F240) if
this setting has a higher value.
Direct Access Number — F244
Parameter Type — Numerical
Factory Default — 0.0
Changeable During Run — Ye s
Minimum — 0.0
Maximum — 5.0
Units — Hz
