Setting example:
(1) To achieve 95% of speed command output in 30msec:
Set
10(msec)
95%)-ln(1-
30(msec)
Sn206 
(2) To achieve 75% of speed command output in 30msec:
Set
22(msec)=
75%)-ln(1-
30(msec)
=Sn206
ln= Natural log
(2)Speed command linear acceleration/deceleration function:
Set Sn205=2 to enable the use of speed command linear acceleration/deceleration function.

Speed command linear
accel/decel time constant
1 msec 1~50000 S
Linear acceleration/deceleration time corresponds to the time in which the speed increases (linearly)
from zero to the rated speed. As shown in the diagram below.
Setting examples:
(1) To achieve 50% of rated speed output in 10msec:
