Overview of Motion Programs
1.2.3 Feed Speeds
1 -36
There are three override setting methods: Motion program, ladder logic program, or the Parame-
ter Setting Screen.
Command speed × override = output speed

Note With the 2000-series Machine Controller, the Override value is always effec-
tive.
1. The Override value is always effective during operation. It can be changed in the ladder logic program,
motion program, and parameter settings while an axis is travelling.
2. If the output speed is out of range after adjustment for the override setting, a parameter setting error will
result.
J Interpolation Feed Speed
D The feed speeds for interpolation commands are designated by numbers following the letter
F. They are sometimes referred to as F designations.
D The F designation for linear and circular interpolation designates the tangential speed.

z Override
Override often means “to invalidate.” In this manual, however, it should be taken to mean “change” the set value.
