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
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.
