Setting example:<br />
(1) To achieve 95% of speed command output in 30msec:<br />
Set<br />
30(msec)<br />
Sn206 =<br />
= 10(msec)<br />
- ln(1- 95%)<br />
(2) To achieve 75% of speed command output in 30msec:<br />
30(msec)<br />
Set Sn206 =<br />
= 22(msec)<br />
- ln(1- 75%)<br />
ln= Natural log<br />
(2)Speed command linear acceleration/deceleration function:<br />
Set Sn205=2 to enable the use of speed command linear acceleration/deceleration function.<br />
Parameter Name Default Unit Setting range<br />
Sn207<br />
Speed command linear<br />
accel/decel time constant<br />

mode<br />
1 msec 1~50000 S<br />
Linear acceleration/deceleration time corresponds to the time in which the speed increases (linearly)<br />
from zero to the rated speed. As shown in the diagram below.<br />
