5.8 Stepper axis - testing
Thiss ection describes the method for testing a stepper axis . The stepper control is an open
loopsystem so no tuningis necessary.

5.8.1 Testingthe drive command output

Thiss ection tests the operation and direction of the axis command out put. It is recommended
thatthe system is initiallytestedand tuned with the motor shaft disconnectedfrom other
machinery.
1. Check that the D rive enable button is
pressed.
2. In the Toolbox, click the Edit & Debug icon.
3. Clic k in the Command window.
4. Type:
JOG.0=2
where0 is the axis (s tepper output) to be
testedand 2 is the s peed.
Note: TheJOG command spec ifies a speed in user units per second, so the speed is
affectedby SCALE ( section 5.3.3).
Ifthere appears to be no puls e or direction output, check the electrical connec tions
betweenthe break out module and the drive.
5. To repeat the tests for rever se moves, type:
JOG.0 = -2
6. To remove the demand and stop the test, ty pe:
STOP.0
