P1�15=0: 0�00~25�00 sec
P1�15=1: 0�0~250�0 sec
Parameters P1.09 and P1.10 are used to provide smooth transitions between speed changes. The
Accel/Decel curve can adjust the S-Curve of the Accel/Decel. When it is enabled, the drive will have
a different Accel/Decel curve by the Accel/Decel Time.
The S-Curve function is disabled when S-Curve Accel/Decel Time is set to 0. It is recommended
to keep a non-zero value in the S-Curve parameters. (Frequency transitions into and out of the
S-Curve areas are much smoother if S-Curve values are non-zero).
• Formula for Actual Acceleration Time:
Actual Acceleration Time = (Accel Time) + (S-Curve Accel Time)/2
Actual Acceleration Time = (P1�01 or P1�03 or P1�05 or P1�07) + (P1�09 or P1�11)/2
[This formula is an approximation� Actual motor Accel will vary depending on load�]
• Formula for Actual Deceleration Time:
Actual Deceleration Time = (Decel Time) + (S-Curve Decel Time)/2
Actual Deceleration Time = (P1�02 or P1�04 or P1�06 or P1�08) + (P1�10 or P1�12)/2
[This formula is an approximation� Actual motor Decel will vary depending on load�]
P1.11 S-Curve Accel Time 2
P1.12 S-Curve Decel Time 2
Range/Units (Format: 16-bit unsigned)
P1.11
and P1�15=0: 0�00~25�00 sec
P1.12
P1�15=1: 0�0~250�0 sec
These parameters allow additional S-Curve Acceleration and Deceleration Time settings which
operate the same way as do S-Curve Acceleration Time 1, P1.09
Deceleration Time 1, P1.10
