F264
UP/DOWN Frequency (UP) Response Time
Program  Frequency  UP/DOWN Frequency Functions
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 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,
respectively. At which point further activation will be ignored.
See Figure 30 on pg. 133 for additional information on the UP/DOWN
Frequency function.
Setup Requirements
F003 — Selects the Command control source; set to Terminal Board.
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 — UP/DOWN Frequency Accel
Time (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 — UP/DOWN Frequency Decel
Time (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
restart, uses this setting as the startup frequency.
Provide a Run command (F or R). The motor will run at the
