Chapter 6 Software Reference

6.1 Introduction

This chapter gives an explanation of the parameters and settings accessed from the

APT software running on a PC. For information on the methods and properties which

can be called via a programming interface, see Appendix D .

6.2 GUI Panel

The following screen shot shows the graphical user interface (GUI) displayed when

accessing the DC driver using the APTUser utility.

Fig. 6.1 Motor driver Software GUI

Jog

- used to increment or decrement the motor position. When the button is clicked,

the motor is driven in the selected direction at the jog velocity one step per click. The

step size and jog velocity parameters are set in the 'Settings' panel (see Section 6.3.).

Travel

- the travel (in mm or degs) of the actuator associated with the GUI panel.

Note

The serial number of the driver unit associated with the GUI panel, the

APT server version number, and the version number (in brackets) of the

embedded software running on the unit, are displayed in the top right

hand corner. This information should always be provided when

requesting customer support.
