Measuring the Analog Zero Pulse Signal
Measurement procedure for checking the analog zero pulse and the analog track signals
Measurement Procedure
Measuring the initial zero pulse position
► Oscilloscope settings:
CH1: Analog zero pulse
500 mV / 10 ms
CH2: Digital zero pulse
2 V / 10 ms
This should be triggered at CH1 with a trigger thresh-
old of approx. 2.5 V.
► Connect the measurement tester to the incremental
encoder.
► Main switch ON
► Connect the oscilloscope to the measurement tester.
► Set the measurement adapter to Calibrate oscillo-
scope and position the signal at the top, center of the
screen.
► Set the switch to "Measure".
► Manually move the gantry over the first zero pulse.
► The following picture should appear on the oscillo-
scope.

Correctly adjusted read unit
Legend
1. There should be no interference pulse in the toler-
ance space of - 0.3 V.
2. The analog zero pulse must exceed the tolerance
space by more then 0.3V.
3. Initial setting (calibrate oscilloscope)
4. Analog zero pulse
5. Digital zero pulse
The digital zero pulse is recorded by the axis test box,
which has been connected to the axis card of the respec-
tive axis. (See section.)
Incorrectly adjusted read unit or contaminated zero pulse
Legend
1. Analog track signal A and B
2. Analog zero pulse
3. Digital zero pulses
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 at connectors X11 and X24 of
the gantry distributor and gantry head distributor (for error monitoring purposes). (calculate ex-
tra time for Y axes, dismantling the covers).
