PG Point 2 Frequency
Program
Frequency
Speed Reference Setpoints
This parameter is used to set the direction, gain, and bias of the
PG
input
terminal when it is used as the
Speed/Direction
-
Control
input.
This parameter sets
PG Point 2 Frequency
and is the frequency that is
associated with the setting of
PG Reference Point 2
).
See
PG Reference Point 1
)
for additional information on this setting.
Direct Access Number — F237

Changeable During Run —
Yes
Minimum — - (Maximum Freq. (
Maximum — + (Maximum Freq. (

Units — Hz
Start Frequency
Program
Special
Frequency Control
The output of the drive 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 drive will accelerate to the programmed setting.
Output frequencies below the
Start Frequency
will not be output from the
drive during startup. However, once reaching the
Start Frequency
, speed
values below the
Start Frequency
may be output from the drive.
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 the
End Frequency
F243)
to 0.0 Hz.
This setting will override the
Dead Band of 0 Hz Frequency Setting Signal
F244)
if this setting has a higher value.
This parameter setting is used during a
Jog
as the
Lower-Limit Frequency
Direct Access Number — F240
Parameter Type —
Numerical
Factory Default —
0.10
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.
The
Run Frequency Hysteresis
(
)
setting 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. When the lower level of the band is reached, the output will go to 0.0
Hz.
