Example - Multiple Moves 

This example makes a coordinated linear move in the XY plane.  The Arrays VX and VY are used to 
store 750 incremental distances which are filled by the program #LOAD.

Vector Mode: Linear and Circular Interpolation Motion 

The DMC-14XX allows a long 2-D path consisting of linear and arc segments to be prescribed.  
Motion along the path is continuous at the chosen vector speed even at transitions between linear and 
circular segments.  The DMC-14XX performs all the complex computations of linear and circular 
interpolation, freeing the host PC from this time intensive task. 

The coordinated motion mode is similar to the linear interpolation mode.  Any pair of two axes may be 
selected for coordinated motion consisting of linear and circular segments.  Note that only one pair of 
axes can be specified for coordinated motion at any given time. 

Specifying Vector Segments 

The motion segments are described by two commands; VP for linear segments and CR for circular 
segments.  Once a set of linear segments and/or circular segments have been specified, the sequence is 
ended with the command VE.  This defines a sequence of commands for coordinated motion.  
Immediately prior to the execution of the first coordinated movement, the controller defines the current
