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 is stopped.
2.
Variable speed test.
By pressing keys kV+ and kV- on the keyboard, the step motor
is supplied with a variable speed, starting from the lowest
and reaching the maximum. When the key is released, the
Be careful during these two tests that the electrical
the mechanical end stop with the step motor still
rotating.
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 corresponding 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 Y 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).
F.4.3.3 R movement test and adjustment
By selecting this service program you can check the functioning of
the R (rotation) movement (step motor, wiring and power supply
from the host computer board PC1) and change the relevant start
position of the rotating cycle.
