P9 ASD Installation and Operation Manual 129
UP/DOWN Frequency (up) Response Time
No Path — Direct Access Only
This parameter functions in conjunction with the settings of F265 , F266 , F267 ,
F268 , and F269 . The purpose of these settings is to set up the ASD to allow an
externally-supplied discrete input signal to control the output frequency of the
ASD.
This method uses the discrete input terminal settings UP/DOWN Frequency
(up) and UP/DOWN Frequency (down) to change the ASD speed. Activation
of either terminal increases or decreases the output frequency at the Accel 1 or
Decel 1 rates, respectively.
Depending on the Delay setting, the UP/DOWN Frequency (up/down)
terminal may perform 1) the increase/decrease function for the duration of
activation or 2) the UP/DOWN Frequency (up/down) terminal may act as a
momentary contact that loads a new commanded frequency upon activation.
In either case, to activate-and-hold will continue the up or down function until
reaching the
Upper-Limit Frequency or the Lower-Limit Frequency , at
which point further activation will be ignored.
See Figure 36 on pg. 131 for additional information on the UP/DOWN
Frequency function.
Setup Requirements
F003 — Selects the Command control source; set to Terminal Block .
F004 — Selects the Frequency Control Mode 1 control source; set to

UP/DOWN Frequency .
F207 — Selects the Frequency Control Mode 2 control source; set to

UP/DOWN Frequency if used.
Set one unused discrete input terminal to UP/DOWN Frequency (up) and
one unused discrete input terminal to UP/DOWN Frequency (down) .
F264 — Sets the system-response delay to the initial activation of the discrete
input terminal UP/DOWN Frequency (up) . Also sets the response delay of
subsequent terminal activations of the UP/DOWN Frequency (up) terminal
during an activate-and-hold.
F265 — Sets the frequency increase amount for each activation of the UP/
DOWN Frequency (up) terminal activation. The rate of the frequency
increase is set at Acceleration Time 1 ( F009 ).
F266 — Sets the system-response delay to the initial activation of the discrete
input terminal UP/DOWN Frequency (down) . Also sets the activation delay
of subsequent terminal activations of the UP/DOWN Frequency (down)
terminal during an activate-and-hold.
F267 — Sets the frequency decrease amount for each activation of the UP/
DOWN Frequency (down) terminal activation. The rate of the frequency
decrease is set at Deceleration Time 1 ( F010 ).
F268 — At power up or after a reset, this parameter setting is used to provide
a starting frequency for the UP/DOWN Frequency function.
F269 — At power down while running, and when enabled, this parameter
writes the running frequency into the F268 location and, upon a system
restart, uses this setting as the startup frequency.
Provide a Run command (F or R). The motor will run at the F268 setting.
