► Manually move the gantry over the first zero pulse.
► The following picture should appear on the oscilloscope.
Correctly adjusted read unit
1. There should be no interference pulse in the toler-
ance space of - 0.3 V.
2. The analog zero pulse has to exceed the switching
threshold by more then 0.3V
3. Initial position
4. Analog zero pulse
5. Digital zero pulse
Incorrectly adjusted read unit or contaminated zero pulse
1. Analog track signal A and B
2. Analog zero pulse
3. Digital zero pulse

Measuring the Digital Zero Pulse Signal
Measurement procedure for checking the digital zero pulse signal and the digital track signals.
NOTICE
Checking the zero pulse
You can also use the BNC socket on the axis test box to check the zero pulse signal (inverted
display of zero pulse signal). The digital signals (for error monitoring purposes) can be checked
at connectors X10 and X24 of the gantry and head interface. (Calculate extra time for Y axes,
dismounting the covers).
NOTICE
Measurement procedure
The procedure for measuring the digital zero pulse is identical to that for measuring the analog
zero pulse.

Checking the Track Signals
Analog Track Signals
To check the track signals, connect the track signal tester and the oscilloscope. (see "5.4.6.1.1 Measur-
ing the Analog Zero Pulse Signal" [ ➙ 239])
► Switch the machine "ON"
► Switch the track signal tester to Calibrate the oscilloscope
► Set the oscilloscope to DC, Refr., Non Store, Auto (20 ms)
► Voltages V/Division decrease up to 0.5 V/Div.
► Set the oscilloscope to X/Y --> an illuminated point will appear!
► Move the point into the middle of the display.
► Set the measuring system tester to Sinus amplifier output
► Manually move the selected axis back and forth.
