F241
Run Frequency
Program
Special Control Parameters
⇒
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.
Run Frequency Hysteresis
Program
⇒
Special Control Parameters
This parameter provides a plus-or-minus value for the Run Frequency setting
(F241).
End Frequency
Program
Special Control Parameters
⇒
This parameter sets the lowest frequency that the drive will recognize during
deceleration before the drive goes to 0.0 Hz.
0 Hz Dead Band Signal
Program
⇒
Special Control Parameters
Band of 0 Hz Frequency
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.
