F503
Acc/Dec Pattern 2
Program  Fundamental 2
This parameter enables a user-selected preprogrammed output profile that controls
the acceleration and deceleration patterns for the Accel/Decel 2 parameter. See
F502 for more information on this parameter.
Settings:
0 — Linear
1 — S-Pattern 1
2 — S-Pattern 2
Panel Acc/Dec Selection
Program  Panel Control
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 conditions.
Switching may be accomplished manually via a properly configured discrete input
terminal or automatically via a threshold frequency 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 (during accel or
decel), the ASD switches to the other profile.
Acc/Dec 1 is set up using parameters
(Pattern), and F505 (Switching Frequency).
Acc/Dec 2 is set up using parameters
F503 (Pattern).
To switch using a discrete input terminal, assign the function A/D 1/2 to an
unused discrete input terminal. Activating or deactivating the A/D 1/2 terminal
toggles to and from the Accel/Decel profiles 1 and 2 and will override the setting
of this parameter.
Figure 27 shows the setup requirements and the resulting output frequency
response when using Switching Frequency settings to control the Acc/Dec
profile of the ASD output.
Accel/Decel Switching Frequency 1
Program  Fundamental 2
This parameter sets the frequency at which the acceleration/deceleration control is
switched from the Accel 1 profile to the Accel 2 profile or from the Decel 2 to the
Decel 1 during a multiple-acceleration/deceleration profile configuration.
See F504 for more information on this parameter.
