1 Introduction
1.1 Introduction
Modern variable speed drive such as the Unidrive SP offer
a multitude of built-in features such as ramp control, speed
control, PID Loops, and even simple position control.
However, the base drive’s functionality is too limited for
many applications. When it comes to more complex
applications, the user must resort to using external
equipment such as PLC's to control the drive from a
system point of view.
However, the flexibility of the Unidrive SP can be
substantially increased by using an SM-EZMotion module.
The SM-EZMotion module is 1 1/2 axis controller with a
dedicated processor that allows the user to write their own
application specific software. The Unidrive SP drive also
offers powerful networking capabilities in addition to the
SM-EZMotion module so that many drives (and other
equipment) can be linked together to communicate
process wide information thus offering a complete
application solution.
1.2 SM-EZMotion Module for
Unidrive SP
The SM-EZMotion module for the Unidrive SP is an option
module that can be fitted to any one of the three expansion
slots in the Unidrive SP. Figure 1 shows the three slot
positions.

The SM-EZMotion module is powered from the Unidrive
SP internal power supply.
When using PowerTools Pro to program the SM-EZMotion
module, the user must indicate which options slot the
module is fitted in. By default, PowerTools Pro will select
Slot 3 for the SM-EZMotion module.
1.3 Development Software
Applications for the SM-EZMotion module are developed
by the user using PowerTools Pro software. PowerTools
Pro is an easy-to use, Windows® based setup and
diagnostics tool. It provides you with the ability to create,
edit and maintain your system setup. You can download or
upload your setup data to or from a device. You can also
save it to a file on your PC or print it for review or
permanent storage.
PowerTools Pro is designed to be the easiest-to-use
software available for the 11/2 axis motion controllers.
