[Pr.35] S-curve ratio
: Refer to Section 5.2 "List of parameters" for setting details.
REMARK

Parameters are set for each axis.
 It is recommended that the parameters be set whenever possible with GX Works2.
Execution by sequence program uses many sequence programs and devices. The
execution becomes complicated, and the scan times will increase.
When a speed change request or override request is given during S-curve
acceleration/ deceleration processing, S-curve acceleration/deceleration
processing begins at a speed change request or override request start.
Command speed before speed change
Speed change request
Speed change (deceleration)
Set the required values for the "acceleration/deceleration method setting" in
the parameters shown in the following table, and write them to the Simple
Motion module.
The set details are validated when written to the Simple Motion module.
Setting
value
Set the acceleration/deceleration method.
0: Trapezoidal acceleration/deceleration processing
1: S-curve acceleration/deceleration processing
Set the acceleration/deceleration curve when "1" is set
in "[Pr.34] Acceleration/deceleration process
selection".
