Acceleration/Deceleration Pattern 1 - 4 Selection
Program
Special
Acc/Dec (1 - 4) Settings
This parameter selects the
Acceleration/Deceleration (Acc/Dec) Profile
to be
used during a multiple-profile configuration.
Four Acceleration times and four Deceleration times may be set up and run
individually.
Acc/Dec Time 1 - 4
may be selected using this parameter setting,
switched via threshold frequencies, or by discrete input terminal.
Settings:
1 — Acc/Dec 1
2 — Acc/Dec 2
3 — Acc/Dec 3
4 — Acc/Dec 4
Each
Acc/Dec
selection is comprised of an
Acceleration (Acc) Time
,
Deceleration (Dec) Time
, and a
Pattern
selection. Selections 1, 2, and 3 have
a
Switching Frequency
setting. The
Switching Frequency
is used as a
threshold frequency that, once reached, triggers the ASD to switch to the next
higher
Acc/Dec
selection (i.e., 1 to 2, 2 to 3, or 3 to 4).
Switching Frequency
settings are also used during deceleration. A switching frequency setting is not
required for
Acc/Dec 4
.
The figure below shows the setup requirements and the resulting output
frequency response when using
Switching Frequency
settings to control the
Acc/Dec
response of the ASD output
Using Acc/Dec Switching
.
While operating using
S-Pattern 1
, the system performance may be further
enhanced by the adjustment of parameters
-
. These settings provide
for upper and lower
Acc/Dec
limit adjustments. These settings are used to
extend or shorten the upper or lower
Acc/Dec
curve.
Note:
If operating from the
Hand
mode, press
ESC
from the
Frequency Command
screen to access this parameter.
To switch using the
Terminal Board
, assign the functions
Acc/Dec
Switching 1
and
Acc/Dec Switching 2
to two discrete input terminals.
Activation combinations of the two terminals result in the
Acc/Dec 1 - 4
selections as shown below.
