5.9 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.
5.9.1 Testing the output
This section tests the operation and direction of the output. It is recommended that the system
is initially tested and tuned with the motor shaft disconnected from other machinery.
1. Check that the Drive enable button is
pressed.
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 to be tested and 2 is the
speed.
Note: The JOG command specifies a speed in user units per second, so the speed is
affected by SCALEFACTOR (section 5.4.2).
If there appears to be no pulse or direction output, check the electrical connections
between the breakout module and the drive.
5. To repeat the tests for reverse moves, type:
JOG(0)=-2
6. To remove the demand and stop the test, type:
STOP(0)
