PG Input Point 2 Frequency
Program Frequency Speed Reference Setpoints
This parameter is used to set the direction and speed of the PG input terminals
when the PG terminal are used as the control input.
This parameter sets PG Input Point 2 Frequency and is the frequency that is
associated with the setting of PG Reference Point 2.
See PG Reference Point 1 (F234) for further information on this setting.
Direct Access Number — F237
Parameter Type — Numerical
Factory Default — 80.0
Changeable During Run — Yes
Minimum — -2990.0
Maximum — +299.0
Units — Hz
Start Frequency
Program Special Frequency Control
The output of the ASD will remain at 0.0 Hz until the programmed speed value
exceeds this setting during startup. Once exceeded during startup, the output
frequency of the ASD will accelerate to the programmed setting.
Output frequencies below the Start Frequency will not be output from the
ASD during startup. However, once reaching the Start Frequency, speed
values below the Start Frequency may be output from the ASD.
If the setting of this parameter results in an over-current condition at startup,
reduce the setting of this parameter to a value less than the rated slippage of the
motor.
If zero-speed torque is required, set this parameter and F243 to 0.0 Hz.
This setting will override the setting of F244 if this setting has a higher value.
This parameter setting is used during a Jog as the Lower-Limit Frequency
(see F260).
Direct Access Number — F240
Parameter Type — Numerical
Factory Default — 0.1
Changeable During Run — Yes
Minimum — 0.0
Maximum — 10.0
Units — Hz
Run Frequency
Program Special 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 ASD will not output a signal to the motor until the
lower level of the band is reached.
During deceleration, the ASD will continue to output the programmed
deceleration 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
Parameter Type — Numerical
Factory Default — 0.0
Changeable During Run — Yes
Minimum — 0.0
Maximum — Max. Freq. (F011)
Units — Hz
Run Frequency Hysteresis
Program Special 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 — Yes
Minimum — 0.0
Maximum — 30.0
