8 CONTROL SUB FUNCTIONS
8.4 Functions to Limit the Control
When the "reference axis speed" is set during interpolation control, set so the major axis side becomes the
reference axis. If the minor axis side is set as the reference axis, the major axis side speed may exceed the
"[Pr.8] Speed limit value".
Setting method
To use the "speed limit function", set the "speed limit value" in the parameters shown in the following table, and write them to
the Simple Motion module.
The set details are validated at the next start after they are written to the Simple Motion module.
Refer to the following for the setting details.
Page 407 Basic Setting
• Parameters are set for each axis.
• It is recommended that the parameters be set whenever possible with the engineering tool. Execution by a
program uses many programs and devices. The execution becomes complicated, and the scan times will
increase.

value
Set the speed limit value (max. speed during control). 200000
[Pr.31] JOG speed limit
value
Set the speed limit value during JOG operation (max. speed during control).
(Note that "[Pr.31] JOG speed limit value" shall be less than or equal to "[Pr.8]
Speed limit value".)
