To start the program, command
XQ #A
Execute Program #A
This program moves X to an initial position of 1000 and returns it to zero on increments of half the distance. Note,
_TPX is an internal variable which returns the value of the X position. Internal variables may be created by
preceding a DMC-1700/1800 instruction with an underscore, _.

Example 15 - Linear Interpolation
Objective: Move X,Y,Z motors distance of 7000,3000,6000, respectively, along linear trajectory. Namely, motors
start and stop together.

Example 16 - Circular Interpolation
Objective: Move the XY axes in circular mode to form the path shown on Fig. 2-8. Note that the vector motion
starts at a local position (0,0) which is defined at the beginning of any vector motion sequence. See application
programming for further information.
