Introduction

Modern variable speed drive such as the Unidrive SP/Digitax ST 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/Digitax ST can be substantially increased by using an EZMotion. EZMotion is 1 1/2
axis controller with a dedicated processor that allows the user to write their own application specific software. The Unidrive SP/
Digitax ST drive also offers powerful networking capabilities in addition to EZMotion so that many drives (and other equipment)
can be linked together to communicate process wide information thus offering a complete application solution.

2.1

SM-EZMotion Module for Unidrive SP

The SM-EZMotion module for the Unidrive SP drive 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.

Figure 1:

Unidrive SP Slot Diagram

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 1 for the SM-EZMotion module.
