6 Programming Motion
Overview
The SMC–4000 provides several modes of motion, including independent positioning and jogging,
coordinated motion, electronic cam motion, and electronic gearing. Each one of these modes is discussed
in the following sections.
The SMC–4000 is a single axis controller and uses X-axis motion only. The example applications
described below will help guide you to the appropriate mode of motion.
Example Application Mode of Motion Commands
Absolute or relative positioning where
each axis is independent and follows
prescribed velocity profile.
Independent Axis Positioning PA,PR
SP,AC,DC
Velocity control where no final endpoint is
prescribed. Motion stops on Stop
command.
Independent Jogging JG
AC,DC
ST
Motion Path described as incremental
position points versus time.
Contour Mode CM
CD
DT
WC
2, 3, or 4-axis coordinated motion where
path is described by linear segments.
Linear Interpolation LM
LI,LE
VS,VR
VA,VD
Electronic gearing where slave axis is
scaled to master axis which can move in
both directions.
Electronic Gearing GA
GR
Master/slave where slave axes must follow
a master such as conveyer speed.
Electronic Gearing GA
GR
Moving along arbitrary profiles or
mathematically prescribed profiles such as
sine or cosine trajectories.
