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

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 (
).
The Switching Frequency is used as a threshold frequency that,
once reached, signals the ASD to switch to the other profile.
