[Pr.34] Acceleration/deceleration process selection
Set whether to use trapezoid acceleration/deceleration or S-curve acceleration/deceleration for the acceleration/deceleration
process.
Refer to the following for details.
Page 298 Acceleration/deceleration processing function
Speed
The acceleration and deceleration are linear.
<Trapezoid acceleration/deceleration>
■Buffer memory address
Refer to the following for the buffer memory address in this area.
Page 399 Positioning parameters: Detailed parameters 2
[Pr.35] S-curve ratio
Set the S-curve ratio (1 to 100%) for carrying out the S-curve acceleration/deceleration process.
The S-curve ratio indicates where to draw the acceleration/deceleration curve using the Sin curve as shown below.
B/2
S-curve ratio = B/A × 100%
■Buffer memory address
Refer to the following for the buffer memory address in this area.
