1-1-1 Overview
The R88A-MCW151 is a 1.5-axis Motion Control (MC) Unit which is con-
nected to the W-series Servo Driver. The MC Unit provides direct control of
the Servo Driver, enables both speed and torque control and has access to
detailed Servo Driver data. To support a multi-axis control application, the MC
Unit features both an encoder input and output connection.
There are two types of the MCW151 Motion Controllers, according to the
communication interface which is integrated into the Unit.
The multi-tasking BASIC motion control language provides an easy to use
tool for programming advanced motion control applications.
Three types of motion control are possible: point-to-point, continuous path
and electronic gearing.
Point-to-point Control Point-to-point (PTP) control enables positioning independently for each axis.
Axis specific parameters and commands are used to determine the paths for
the axes.
Continuous Path Control Continuous path (CP) control enables the user not only to control the start and
end positions, but also the path between those points. Possible multi-axis
paths are linear interpolation and circular interpolation. Also user defined
paths can be realized with the CAM control.
Electronic Gearing Electronic gearing (EG) enables controlling an axis as a direct link to another
axis. The MC Units supports electronic gear boxing, linked moves and CAM
movements and adding all movements of one axis to another.
