the C (cassette) movement (step motor, wiring and power supply
from the host computer board PC1) and change the relevant start
position of the rotating cycle.
The following message will appear on the display:
-C- TEST & ADJ.
+0 +0 XYRABC
where:
with respect to the reset position
start position of the movement
ments :
- X = start position of the X movement
- Y = start position of the Y movement
- RAB = start position of the rotation movement
(2 optoswitches)
- C = start position of the cassette movement
has not been activated.
There are three different tests:
1.
Constant speed test.
By pressing keys mA+ and mA- on the keyboard, the step
motor is supplied so as to have a constant speed.
By releasing the key, the movement stops.
2.

3.
Modify the movement start position.
With this procedure you can modify the start position of the
movement via software, instead of by changing the actuator
of the relevant optoswitch.
Pressing keys s+ and s- will change the number indicating
the start position (default = 0).
The correspondence between the number displayed and
the shift in mm is the following:
mm = 0.0728 X n displayed
This procedure is useful when you have to change the start posi-
tion of the C movement after having checked the system
with the image quality phantom (see the paragraph "Verify
the centering of the system with the image quality phantom" in
this section).
