Entering S-curve Characteristics in the Acceleration and Deceleration Time
By performing acceleration and deceleration using an S-curve pattern, shock at start and stop of the machine
can be reduced
Two S-curve characteristic times can be set: At acceleration start and at acceleration end. For deceleration
start and end the S-curve times are fixed to 0.2 sec.

Output frequency
C1-03 C1-01
When output frequency ≥ C1-11, acceleration and deceleration are performed using
Acceleration/deceleration Time 1 (C1-01, C1-02).
When output frequency < C1-11, acceleration and deceleration are performed using
Acceleration/deceleration Time 2 (C1-03, C1-04).
