Programming Motion Control in C

The chapter introduces you to the C language and programming with
the Motion Library functions in Ultraware 1.3. The purpose of this
chapter is to:
• Review some of the basic C language constructs.
• Help you gain experience in developing Ultraware programs that
control the motion of a motor.
• Have you create and run motion programs using the Ultraware
Motion Library.
This chapter assumes that you have read, and understand, the
contents of the Ultraware User Manual (2098-UM001F-EN-P). That
means:
• The Ultra5000 system is setup and tuning is complete.
• Controlled motion was initiated through direct mode commands,
such as Jog Forward.
If you do not have a basic understanding of C
IMPORTANT
programming, you should consider reading one of
the many books available or obtain instruction on C
programming. This manual is not intended to
provide you with the instruction necessary to
become a proficient C programmer.
Until now all motion occurred in what is called the direct mode; you
told the Ultra5000 what to do by selecting direct commands from the
Ultraware Commands menu. It is far more useful to have all the
moves a machine axis will do, along with I/O statements, etc., in a
program. In this chapter you will build several C programs that
automate the control of a motor and drive system.
