6.4 Stepper axis - testing

This section describes the method for testing a stepper axis. The stepper control is an open loop system so no tuning is necessary.

6.4.1 Testing the output

This section tests the operation and direction of the output. It is recommended that the system is initially tested with the motor shaft disconnected from other machinery.

1.Check that the Drive enable button is pressed (down).

2.In the Toolbox, click the Edit & Debug icon.

3.Click in the Command window.

4.Type:

JOG.0=2

where 0 is the axis (stepper output) to be tested and 2 is the speed.

The JOG command specifies the speed in user units per second, so the speed is

affected by SCALEFACTOR (section 6.3.2). If you have not selected a scale, the command JOG.0=2 will cause rotation at only 2 half steps per second, so it may be necessary to increase this figure significantly, to 200 for example. If you have selected a scale that provides user units of revolutions (as described in section 6.3.2) JOG.0=2 will cause rotation at 2 revolutions per second. If there appears to be no step or direction output, check the electrical connections on the backplane.

5.To repeat the tests for reverse moves, type:

JOG.0 = -2

6.To remove the demand and stop the test, type:

STOP.0
