To establish a V/f pattern with a straight line from Fmin to Fa,
set Fb = Fmin, and Vc = Vmin.
IMPORTANT
When entering a setting for one of these constants, an improper
constant fault will occur if any part of the following relationships
among constants
no-02
thru
no-08
is NOT TRUE:
a) Fmax
³
Fa
³
Fb
³
Fmin
b) Vmax > Vc
³
Vmin
The attempted setting value will blink for approx. 3 seconds,
then the display will again show the previous constant setting.
3.5
ACCEL / DECEL TIMES
These constants set the normal accel and decel times required
for the GPD 333 output to ramp from Fmin to Fmax or from
Fmax to Fmin, respectively.
If a Multi-function Input (terminal 3, 4 or 5) is programmed as
Accel/Decel Time Change command (see paragraph 3.15), the
GPD 333 uses the settings in
these
constants as its accel and
decel times when that input is closed.
