Motion Control Chapter 7
Use the Micro800 Motion Control Feature
The Micro800 motion control feature has the following elements. New users
need to have a basic understanding of the function of each element to effectively
use the feature.
To use the Micro800 motion feature, you need to:
1. Configure the Axis Properties
See Motion Axis Configuration in Connected Components Workbench
on page 109 for instructions.
2. Write your motion program through the Connected Components
Workbench software
For instructions on how to use the Micro800 motion control feature, see
the quickstart instructions, Use the Motion Control Feature on Micro800
Controllers, publication 2080-QS001
.
3. Wire the Controller

Element Description Page
Pulse Train Outputs Consists of one pulse output and
one direction output. A standard
interface to control a servo or
stepper drive.

Axis From a system point of view, an axis
is a mechanical apparatus that is
driven by a motor and drive
combination. The drive receives
position commands through the
Micro800 pulse train outputs
interface based upon the PLC
execution of motion function blocks.
On the Micro800 controller, it is a
pulse train output and a set of
inputs, outputs, and configuration.

Jerk Rate of change of acceleration. The
Jerk component is mainly of
interest at the start and end of
motion. Too high of a Jerk may
induce vibrations.
