5.8 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.
5.8.1 Testing the drive command output
This section tests the operation and direction of the axis command 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 (stepper output) 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 SCALE (section 5.3.3).
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 =
6.To remove the demand and stop the test, type:
STOP.0
