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
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 Fre-
quency (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 37 on pg. 131
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 Fre-
quency (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 acti-
vation delay of subsequent terminal activations of the UP/DOWN Fre-
quency (down) terminal during an activate-and-hold.
F267
— Sets the frequency decrease amount for each activation of the
UP/DOWN Frequency (down)
quency 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
F269
— At power down while running, and when enabled, this parame-
ter writes the running frequency into the
tem restart, uses this setting as the start up frequency.
