UP/DOWN Frequency Functions
This parameter functions in conjunction with the parameter settings of
,
. 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
for additional information on the UP/DOWN
Frequency function.
Setup Requirements
— Selects the Command control source; set to Terminal Board.
— Selects the Frequency Control Mode 1 control source; set to
UP/DOWN Frequency.
— 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).
— 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.
— Sets the frequency increase amount for each activation of the
U
P/DOWN Frequency (up) terminal activation. The rate of the frequency
increase is set at Acceleration Time 1 (
).
— Sets the system-response delay to the initial activation of the
d
iscrete 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.
— Sets the frequency decrease amount for each activation of the
UP/DOWN Frequency (down)
terminal activation. The rate of the fre
-
quency decrease is set at Deceleration Time 1 (
).
— At power up or after a reset, this parameter setting is used to
provide a starting frequency for the
UP/DOWN Frequency
function.
At power down while running, and when enabled, this parame
-
ter writes the running frequency into the
location and, upon a sys
-
tem restart, uses this setting as the start up frequency.
Provide a Run command (F or R). The motor will run at the
setting.
