7.4.1.2 Check the track signals
7.4.1.2.3 Analog track signals
To check the track signals, connect the track signal tester and the oscilloscope. (see Section 7.4.1.1.1
Measurement of the analog zero pulse signal [J 150]).
X Switch the machine "ON"
X Switch the track signal tester to the correct position
Calibrate the oscilloscope
X Switch the oscilloscope to the correct position
DC, Refr., Non Store, Auto (20 ms)
X Voltages V/Division decrease up to 0,5 V/Div.
X Switch the oscilloscope to the correct position
X/Y
--> Illuminated point will appear!
X Move the point into the middle of the display
X Switch the measurement tester to the correct position
Sinus amplifier output
X Move the axis by hand over the whole incremental scale (to check the scale quality).
X The following picture should appear.
7.4 - 3: Analog track signals A and B in X/Y mode
X Switch the oscilloscope to the normal mode.
X The following picture should appear.
7.4 - 4: Analog track signals 90° phase shift

7.4.1.2.4 Digital Track signals
7.4.2 Check dynamic X-axis
The inspection of dynamics occurs with the following signals:
Deviation of position
Uncommutated target current value
Vnom. – speed signal
End signal ( Adapter board Axis in target position)
Actual position = target position signal (upstream end position signal)
Legend:
1. Track A
2. Track B
To check the digital track signals, connect the
track signal tester and the oscilloscope. (see Sec-
tion 7.4.1.1.2 Measuring the Digital Zero Pulse Si-
gnal [J 152]).
The measurement procedure is identical as that
described at Point 7.4.1.2.3 Analog track signals
[J 154] .
NOTE:
For detailed information about checking the dynamics, refer to the settings
instructions.
Before adjusting the axes, ensure that the machine has reached its operating
temperature. Switch the machine on at least 30 minutes before you begin work.

7.4.2.1 Test setup with axis testbox
7.4 - 5: Test setup with axis testbox
Additional connection at channel 4 could be the actual position = target position signal from trigger
m1/2 of the adapter board or the speed signal Vreg (Vnom.).
NOTE:
Use an RC - filter to record the "uncommutated motor current target value"
(current signal).
