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.

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.
