5.1 Basics of Positioning Control
Advanced S-curve acceleration/deceleration processing
Processing for smooth acceleration/deceleration can be executed by using the Advanced S-curve acceleration/deceleration
function. The acceleration section is set as a sine curve as shown in the diagram below.
Set the advanced S-curve acceleration/deceleration by the parameter block (
Page 221 Advanced S-curve acceleration/
deceleration) or servo program.
Advanced S-curve acceleration/deceleration can be set by the servo program is following two methods.
■
Specification by numerical value
Advanced S-curve acceleration/deceleration system and advanced S-curve acceleration/deceleration ratio are set a
numerical value.
