Note 1. The setting unit of acceleration or deceleration time is determined by the set value in n018
(acceleration/deceleration time setting unit).
n018 set to 0 (0.1 s unit): Setting range from 0.0 to 6,000 s (0.0 to 999.9 s or 1,000 to 6,000 s)
n018 set to 1 (0.01 s unit): Setting range from 0.00 to 600.0 s (0.0 to 99.99 s or 100.0 to
600.0 s)
Note 2. When n018 is set to 1 (0.01 s unit), the default value of acceleration or deceleration time will be
set to 10.00.
H S-shape Acceleration/Deceleration Characteristic (n023)
• Trapezoidal and S-shape acceleration and deceleration are available. Using the S-shape characteris-
tic function for acceleration and deceleration can reduce shock to the machinery when stopping or
starting.
• Any one of three S-shape acceleration/deceleration times (0.2, 0.5, and 1.0 s) is selectable.

Value Description
0 No S-shape acceleration/deceleration characteristic (Trapezoidal acceleration/deceleration)
1 S-shape acceleration/deceleration characteristic time is 0.2 s
2 S-shape acceleration/deceleration characteristic time is 0.5 s
3 S-shape acceleration/deceleration characteristic time is 1.0 s
Note When the S-shape acceleration/deceleration characteristic time is set, the acceleration and
deceleration times will be lengthened according to the S-shape at the beginning and end of accel-
eration/deceleration.
