Fig. 10.3.14 Speed and P gain for the X2 axis (P gain too high)
10.3.6.5 X axis
General preparatory work
● The gluing heads and cameras must be fitted in order to set the axes.
● Use an RC filter to record the current curve and the diagnostic strip test point signal.
● Carry out a head reference sequence and an x reference sequence.
● Switch the machine on for approximately 30 minutes.
Setting the offset
Preparation:
● Connect an axis test box to the axis board and set the position display to axis number 0.
● Change the MA data for offset adjustment and reference the axis (see Table 10.3.1).
● Position the X axis at 200,000.
Setting:
● Use the offset potentiometer on the servo board to set the axis position to 200,000 ± 1 digit.
Check:
● The axis position display should not deviate from the value of 200,000 by more than 1 digit.

Setting the speed (see Fig. 10.3.15)
Preparation:
● Change the MA data for adjusting the speed and then reference the axis (see Table 10.3.2)
● Connect an axis test box to the axis board and set to time measurement - axis 0.
● Set the axis to continuous operation for a distance of 100,000 - 300,000 digits.
Setting:
● Increase the P gain on the servo board until the axis can be easily positioned.
● Use the tacho potentiometer on the X servo board to set the f/V converter signal at the diagn. strip
to the zero line ± 500 mV once the speed is reached (max. setpoint values) (see Fig. 10.3.15).
Check:
● The positioning time must be 980ms ±15ms (time measured with a suitable P gain)

Adjusting the P gain (see Fig. 10.3.16)
Preparation:
● Set the MA data as for adjusting the speed (see Table 10.3.2)
● Set the axis to continuous operation from 195,000 to 205,000.
Setting:
● Use the servo board potentiometer to increase the P gain until a slight tendency to vibrate occurs
at the position deviation.
● Reduce or increase the P gain until the position deviation no longer rises or dips (see Fig.
10.3.16).

Check:
● Set the positioning distance to 120,000-280,000 and 100,000-300,000.
● The position deviation and current curve must not rise for either distance.
● During the reference sequence, the axis must not rise or give off a loud humming noise.
● The positioning time for the distance 120,000 to 280,000 must be 815 ms ±10 ms.
● The positioning time for the distance 100,000 to 300,000 must be 980 ms
±
10 ms.
Positioning quality
Preparation:
● Reset the MA data to basic data (see Table 10.3.4) and reference the axis.
● Set the distance in accordance with the distance table (see Table 10.3.9) and check the position
deviation.
● 50ms after the end signal, the position deviation must not exceed 5 digits.
Check:
● Set the distance in accordance with the distance table and check the time. Check the settings and
the machine, if necessary.
● The end signal will not be output until the post-pulse oscillations in the position deviation have
fallen below the specified value (position deviation in REAL.MA), since this could cause signifi-
cant fluctuations in the positioning time.

track signals
10.4.1 Basic test set-up
● Prepare the automatic placement machines for the measurement as follows:
- Switch ON at the main switch
- Open the protective cover
- Use a (plastic) feeler gauge to set the air gap between the scanning head (sensor head of the measuring
system) and the track rule to 0.4 mm +
0.05 mm. Check this setting at the start, middle and end of the
travel range.
- Plug in the jumper for the counting direction (see Fig. 10.4.2 and Fig. 10.4.3).
