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.

gure 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.

Accel/Decel Switching Frequency 1
Program Special  Accel/Decel Special
This parameter sets the frequency at which the acceleration control is switched
from the Accel 1 profile to the Accel 2 profile during a multiple-acceleration
profile configuration.
Direct Access Number — F505

Factory Default — 0.00
Changeable During Run — Yes
Minimum — 0.00
Maximum — Max. Freq. (F011)
Units — Hz
