Function of Each Parameter
15
Note: For n09, n11, and n12, the unit of setting is as follows:
Values will be set in 0.1-Hz increments if the frequency is
less than 100 Hz and 1-Hz increments if the frequency is
100 Hz or greater.

Note: 1. Set the parameters so that the following condition will
be satisfied.
n14 x n12 < n11 x n09
2. The value set in n13 will be ignored if parameters n14
and n12 are the same in value.

Acceleration/Deceleration Time Settings
(n16 to n19)
The acceleration time is the time required to go from 0% to 100%
of the maximum frequency and the deceleration time is the time
required to go from 100% to 0% of the maximum frequency. The
actual acceleration or deceleration time is obtained from the fol-
lowing formula.
Acceleration/Deceleration time =
(Acceleration/Deceleration time set value) × (Frequency refer-
ence value) ÷ (Max. frequency)

S-shape Acceleration/Deceleration Characteristic
(n20)
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 character-
istic time is set, the acceleration and deceleration times
will be lengthened according to the S-shape at the begin-
ning and end of acceleration/deceleration.

Note: 1. Values will be set in 0.1-Hz increments if the frequency is less
than 100 Hz and 1-Hz increments if the frequency is 100 Hz
or over.
2. Frequency reference 1 is enabled with n03 for frequency ref-
erence selection set to 1. (Remote mode)
3. Frequency references 1 to 8 are enabled by setting multi-
step speed references 1, 2, and 3 in n36 to n39 for multi-func-
tion input. Refer to the following table for the relationship be-
tween multi-step speed references 1 to 3 and frequency ref-
erences 1 to 8.
