ODC001 Servo Motor Driver

4.3

Using the APT User Utility

The APT User.exe application allows the user to interact with any number of APT
hardware control units connected to the PC USB Bus (or simulated via the APTConfig
utility). This program allows multiple graphical instrument panels to be displayed so
that multiple APT units can be controlled. All basic operating parameters can be set
through this program, and all basic operations (such as motor moves) can be initiated.
Hardware configurations and parameter settings can be saved, which simplifies
system set up whenever APT User is run up.

Fig. 4.2 Typical APT User Screen

1) Run the APT User program - Start/Programs/Thorlabs/APT/APT User.
