Acceleration/Deceleration Pattern 1 – 4
Program Special ACC/DEC Special
Two Accel/Decel profiles may be set up and run individually.
Accel/Decel Time 1 or 2 may be selected using this parameter
setting. The system may also be configured to switch between
the number 1 and the number 2 profiles under user-set condi-
tions.
Switching may be accomplished manually via a properly config-
ured discrete input terminal or automatically via a threshold fre-
quency setting.
This parameter is used to manually select one of the configured
accel/decel profiles to be used.
Settings:
1 — Acc/Dec 1
2 — Acc/Dec 2
Each Accel/Decel selection is comprised of an Acceleration
Time, Deceleration Time, and a Pattern selection.
Accel/Decel 1 includes a Switching Frequency setting (F505).
The Switching Frequency is used as a threshold frequency that,
once reached, signals the ASD to switch to the other profile.
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), and F503 (Pattern).
To switch using a discrete input terminal, assign the function A/D
1/2 to an unused discrete input terminal. Activating or deactivat-
ing the A/D 1/2 terminal toggles to and from the Accel/Decel pro-
files 1 and 2 and will override the setting of this parameter.
Figure 38 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.
Note: If operating from the Local mode, press ESC from the
Frequency Command screen to access this parameter.

Figure 38. Using Acc/Dec Switching.
1 — Accel time 1 (F009 setting)
2 — Accel time 2 (
F500 setting)
3 — Decel time 2 (
F501 setting)
4 — Decel time 1 (
F010 setting)
F505 — Frequency threshold setting at
which the 1-to-2 and the 3-to-4 switch
during the accel/decel profile.
