Q9 ASD Installation and Operation Manual 103
UP/DOWN Frequency (UP) Response Time
No Path — Direct Access Only
This parameter functions in conjunction with the parameter settings of F265 ,
F266 , F267 , F268 , and F269 . The purpose of these settings is to setup 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 the increase/decrease function for the duration of the
activation or 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,
respectively. At which point further activation will be ignored.
See Figure 26 on pg. 105 for more 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.
