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

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:
100%
Set Sn207 = 10(msec) × = 20(msec)
50%
(2) To achieve 75% of rated speed output in 10msec:
100%
Set Sn207 = 10(msec) × = 13(msec)
75%
