3 MAJOR POSITIONING CONTROL
3.1 Overview of the Major Positioning Controls
• In the continuous path control, the speed is not changed when the positioning data No. is switched by the
near pass function. (
• The RD75 holds the command speed set with the positioning data and the latest speed value set with the
speed change request as [Md.27] Current speed to control with the current speed when -1 is set for the
command speed. (Depending on the relation between the movement amount and the speed, the feedrate
may not reach the command speed. However, even in that case, the current speed will be updated.)
• When the address for the speed change is identified beforehand, create and execute the positioning data
for the speed change with the continuous path control to perform the speed change without requesting the
speed change using a program.
