Selecting a new propoZ position
The propoZ position can be re-programmed as many times as the user requires.
Ensure the DSi is calibrated and has completed the initialisation routine. You will notice that the LED
on the DSi flashes 'blank' as it passes the last programmed propoZ position.
To change the propoZ position...
1) Rotate the axis to the position where you would ideally like the reference (index) position to be.
2) Using a hex-key or other suitable tool, press the recessed propoZ button on the front of the DSi.
The LED will show orange while the button is pressed. The new propoZ position is stored as the
button is released. If the axis remains at that position, the LED shows blank after the button is
released, indicating that the axis is at the propoZ position.
Hint: you may find it useful to press and hold the propoZ button while you adjust the axis
position slightly, then release the button at the optimum point.
3) The controller may now 'emergency stop' as the reference (index) is output at a new position.
It is recommended that the controller is restarted to ensure the controller is using the new
reference (index) position.
4) After the controller has been restarted, the DSi will start the initialisation routine, indicated by
a flashing green LED and a 'low' K output . Rotate the axis in one direction (either clockwise or
anti-clockwise) until the LED goes solid green and the K output goes 'high'.
The new propoZ position will be indicated by a blank flash of the LED.
NOTE: you can select a new propoZ position at any time when the LED is solid green,
simply by pressing the propoZ button.
5) Small black adhesive covers are provided for the propoZ button and head orientation switch to
reduce ingress of dust.
