► Move the gantry manually over the zero pulse (see instructions or description of zero pulse search).
► The following picture should appear on the oscilloscope.

6.4.1.2 Measuring the Digital Zero Pulse Signal
NOTICE
When the gantry is positioned at the hardware stop, an area of 25mm begins, in which no zero
pulse search is permitted. Check the first zero pulse after this area, on the incremental scale.

1. There should be no interference pulse in the
tolerance space of - 0.3 V.
2. The analog zero pulse must overshoot the switching
threshold by more then 0.3V.

NOTICE
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 can be checked (for error location) at
connectors X10 and X24 of the gantry and at the head interface (calculate extra time for Y axes,
dismantling the covers).

6.4.2.1 Analog Track Signals
To check the track signals, connect the track signal tester and the oscilloscope. (see "6.4.1.1 Measuring
the Analog Zero Pulse Signal" [ ➙ 197])
► Switch the machine on.
► Switch the track signal tester to Calibrate oscilloscope.
► Switch the oscilloscope to DC, Refr., Non Store, Auto (20 ms).
► Voltages V/Division decrease up to 0.5 V/Div.
► Switch the oscilloscope to X/Y --> Illuminated point will appear!
► Move the point into the middle of the display.
► Measurement system to position Sinus amplifier output.
► Manually move the selected axis back and forth.
