6.4.2 Checking the Track Signals
6.4.2.1 Analog Track Signals
To check the track signals, connect the track signal tester and the oscilloscope. (see Section (6.4.1.1
Measuring the Analog Zero Pulse Signal
J
222 ) )
X Switch the machine on.
X Switch the track signal tester to
Calibrate oscilloscope.
X Switch the oscilloscope to
DC, Refr., Non Store, Auto (20 ms).
X Voltages V/Division decrease up to 0.5 V/Div.
X Switch the oscilloscope to
X/Y
--> Illuminated point will appear!
X Move the point into the middle of the display.
X Measurement system to position
Sinus amplifier output.
X Manually move the selected axis back and forth.
6-17: Analog track signals A and B in X/Y oscilloscope mode
X The adjacent picture should appear on the
oscilloscope.
NOTE:
A new version of the incremental
encoder (one field lens) can recognize
signals from 1.8 to 3.6 Vss.
6-18: Analog track signals 90° phase shift
X Switch the oscilloscope to normal operation.
X The adjacent picture should appear on the
oscilloscope.

6.4.2.2 Digital Track Signals
To check the digital track signals, connect the track signal tester and the oscilloscope. (see Section
(6.4.1.2 Measuring the Digital Zero Pulse Signal
J
224 ) )
The measurement sequence is identical to that described in Section (6.4.2.1 Analog Track Signals
J
226 ) .
6-19: Digital track signals 90° phase shift
