(Note) The Acceleration and Deceleration are set in the “Acceleration” and “Deceleration” data
boxes on the position data.
S-shaped Motion
The S-shaped curve is described where at first in the acceleration, the line is gentle, but along
the way, it suddenly becomes steep.
Use it in such application that setting the acceleration/deceleration rate high is desiredbecause
high takt time is required, but in the movement start or immediately before stop, low
acceleration/deceleration rate is favorable.
Velocity
Time
(Note) The S-shaped motion degree is set using the parameter No.56 “S-Shaped Motion Ratio
Setting”. The setting unit is % and setting range is from “0” to “100”.
(The above figure shows the image graph with the Parameter No.56 set to “100”.)
When it is set to “0”, the S-shaped motion is disabled.
However, the setting is not reflected on the jog operation or inching operation performed
using the personal computer or teaching pendant.
