P1�01~P1�08)

This parameter selects whether the Acceleration/Deceleration will be changed mid-ramp by
changing the digital inputs, or if the Acceleration/Deceleration changes at Transition frequencies
(P1.17 and P1.18).
If using Transition Frequencies, acceleration starts at Acceleration Time 1 and transitions to
Acceleration Time 2; deceleration begins with Deceleration Time 2 and transitions to Deceleration
Time 1.
S-Curve Time settings are also in effect and will smooth the transition from one rate to the
another.

If using P1.16=1 (Transition Frequencies), do not set any Mult-Function Inputs to #8 or #9 (Accel/
Decel selection by Input terminals). The inputs can overwrite the Transition Frequencies.

These parameters set the frequency at which the acceleration ramp transitions automatically from
Accel Time 1 (P1.01 ) to Accel Time 2 (P1.03), and the frequency to transition from Decel Time 2
(P1.04) to Decel Time 1 (P1.02 ).
•
These parameters are active only if Accel/Decel Transition Method (P1�16) is set to 1�
•
Acceleration Time 1 (P1�01) is the first Accel Time used� Once the frequency set in P1�17 is
reached, Acceleration Time 2 (P1�03) is used until commanded speed is achieved�
•
Deceleration Time 2 (P1�04) is the first Decel Time used� Once the frequency set in P1�18 is
reached, Deceleration Time 1 (P1�02) is used until a full stop is achieved�
