Acc/Dec Pattern 1 – 4
Program
Special
Acc/Dec Special
Four Acceleration times and four Deceleration times may be set up and run
individually.
Accel/Decel Time 1
–
4
may be selected using this parameter
setting or switched via threshold frequencies, or by discrete input terminal.
This parameter is used to select one of the four configured accel/decel profiles
to be used.
Settings:
1 — Acc/Dec 1
2 — Acc/Dec 2
3 — Acc/Dec 3
4 — Acc/Dec 4
Each Accel/Decel selection is comprised of an
Acceleration Time
,
Deceleration Time
, and a
Pattern
selection. Selection 1, 2, and 3 have a
Switching Frequency
setting. The
Switching Frequency
is used as a threshold
frequency that, once reached, the ASD switches 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
.
Acc/Dec 1
is set up using parameters
F009
(Acc Time),
F010
(Dec Time),
F502
(Pattern), and
F505
(Switching Frequency).
Acc/Dec 2
is set up using parameters
F500
(Acc Time),
F501
(Dec Time),
F503
(Pattern), and
F513
(Switching Frequency).
Acc/Dec 3
is set up using parameters
F510
(Acc Time),
F511
(Dec Time),
F512
(Pattern), and
F517
(Switching Frequency).
Acc/Dec 4
is set up using parameters
F514
(Acc Time), and
F515
(Dec Time),
F516
(Pattern).
This parameter (
F504
) is used to manually select
Acc/Dec 1
–
4
.
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 in
Table 4
.
Figure 30
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.
While operating using
S-Pattern 1
the system performance may be further
enhanced by the adjustment of parameters
F506
–
F509
. 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
Local
mode, press
Esc
from the
Frequency
Command
screen to access this parameter.
