Chapter 5

5.2 Verifying Software Operation

5.2.1 Initial Setup

The APT Software should be installed (Section 3.1.) and the power up procedure

performed (Section 3.3.) before software operation can be verified.
1) Run the APTUser utility and check that the Graphical User Interface (GUI) panel

appears and is active.

Fig. 5.1 GUI panel showing jog and ident buttons

2) Click the ‘Ident’ button. The ENABLE LED on the front panel of the associated

driver flashes. This is useful in multi-channel systems for identifying which driver

unit is associated with which GUI.

3) Click the ‘Home/Zero button on the GUI panel and check that the motor or axis

connected to the driver moves. See Section 5.4. for further details on homing.

Follow the tutorial steps described in Chapter 5 for further verification of operation.

Note

The 'APT Config' utility can be used to set up simulated hardware

configurations and place the APT Server into simulator mode. In this way it

is possible to create any number and type of simulated (virtual) hardware

units in order to emulate a set of real hardware. This is a particularly useful

feature, designed as an aid to application program development and testing.

Any number of 'virtual' control units are combined to build a model of the

real system, which can then be used to test the application software offline.

If using real hardware, ensure that Simulator Mode is disabled. If using a

simulated setup, enable Simulator Mode and set up a ‘Simulated

Configuration’ - see Section 5.11. or the

APTConfig

helpfile for detailed

instructions.
