UP/DOWN Frequency (up) Response Time
No Path — Direct Access Only
This parameter functions in conjunction with the 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 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
for additional information on the
UP/DOWN
Frequency
function.
Setup Requirements
Command
control source; set to
Terminal Block
.
Frequency Control Mode 1
control source; set to
UP/DOWN Frequency
.
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 Frequency (up)
terminal
during an activate-and-hold.
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
(
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.
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
—
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 parameter
writes the running frequency into the
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
setting.
