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.

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.

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)
S-shape acceleration/deceleration characteristic time is 0.2 s
1
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.
