5.8 Stepp er 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 t hat 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 = -2
6. To remove the demand and stop the test, type:
STOP.0
