● Move the gluing head holder to the minimum position.

Fig. 10.3.5 Overview: Tensioning the toothed belt on the X2 axis (illustrated without glue application head)

Key to

1 Free hole for moving the idler pulley

2 Test point (half-way along the free belt length)

3 Measuring head (illustrated without the stand)

4 Free end of the belt

5 Fixing screw for the idler pulley

6 Idler pulley

● Attach the belt tension measuring device. Position the measuring head just beside the free end of the belt

(approximately 5 - 20 mm). The test point is around half-way along the free belt length (see Fig. 10.3.5).

● Switch on the belt tension measuring device. If "LO BAT" appears on the display, the battery will have to be

charged first.

● Strike the belt sharply to start it vibrating.

PLEASE NOTE

The belt must not be twisted when you strike it since this would make it wobble as it vibrates. Consequently,

as far as possible, you should strike the belt over the entire width. Use an appropriate tool to strike the belt,

e.g. an Allen key. Do NOT strike the belt with your finger.

● The measurement is indicated on the belt tension measuring device in the form of an audible signal. The

measured frequency appears on the display.

● Tensioning the toothed belt:

● Loosen the fixing screw on the idler pulley (see Fig. 10.3.5).

● Push a suitable pin (e.g. drift punch or screwdriver) into the free hole in the toothed belt fastener.

● Use the pin to press the idler pulley against the toothed belt (see Fig. 10.3.5). You could also use the

fixing screw to push the idler pulley. At the same time, tighten the fixing screw of the idler pulley once

more.

● Change the belt tension until the required frequency is reached:

182 Hz (for both toothed belts).

CAUTION

The toothed belt can become stretched if it is overtightened. Precise positioning is not possible if the

toothed belt is stretched.

● Remove the belt tension measuring device.

● Mount the glue application head.

● Close the protective cover and release the emergency stop button.

10.3.6 Adjusting the dynamic behavior of the axes

PLEASE NOTE

- It is only necessary to fundamentally change the dynamic behavior of the axes after certain servicing work,

so check the dynamic behavior before you make any changes.

- Switch the machine on for at least half an hour before you make any adjustments.

- Always adjust the axis boards before adjusting the dynamic behavior of the axes (see Section 10.3.6.1).

10.3.6.3 Adjusting the dynamic behavior of the z axes

Preparation

● Set up glue application heads 1, 2 and 3 with a full glue cartridge.

● Carry out the zero point correction for the z axis(es), if necessary. Ensure that the zero point correction for

the z axis(es) was entered correctly in the MA data.

● Carry out a head reference run.

● Use an RC filter for the current curve (see Fig. 10.3.7).

Adjusting the offset

● Connect the axis testing device to the Z axis board. Use the momentary-contact switch on the axis testing

device to select position display 4 to 6 corresponding to the z axis concerned.

● Set the axis position to 0 ± 1 digits using the offset potentiometer on the servo board.

● Check: The position display must not fluctuate from the value by more than 1 digits.

Setting the speed

● Set the axis testing device to time measurement (set the toggle switch to -1), rotary switch, axis 0 to 2.

● Ensure that the space beneath the z axis is clear.

● Start the axis in continuous mode. Distance: 0 to 400 digits.

● Increase the P gain on the servo board until the axis can be easily positioned.

● Use the tacho potentiometer on the servo board to set the end message signal to 39 ms ± 2 ms (Z dis-

tance down, see Fig. 10.3.8).

● Check: the positioning time for z axis down must be 39 ms ± 2 ms and z axis up must be 40 ms ± 2 ms.

Adjusting the positioning quality

● Push the glue application head to be set over the calibration tool compartment.

● Start the axis in continuous mode. Distance: 0 to pos. calibration tool compartment for the "current sensor"

positioning type.

● Use the ratio potentiometer on the servo board to increase/reduce the P gain until the rising edge of the

setpoint value (at the transition to the position control) clearly starts to round off (see Fig. 10.3.9).

● The current curve must not rise sharply as shown in Fig. 10.3.11.

● Readjust the speed using the tacho potentiometer on the servo board:

- If you are using the old metal calibration tool compartment, the positioning time for z axis down must

be 47 ms ± 2 ms.

- If you are using the new plastic calibration tool compartment, the positioning time for z axis down must

be 52 ms ± 2 ms.

● Check: If the P gain is set incorrectly, the setpoint value will not round off or the current curve will rise

sharply (see Fig. 10.3.10 or Fig. 10.3.11).

- Old calibration tool compartment: positioning time for axis down = approximately 47 ms ± 2 ms, axis

up = 49 ms ± 2 ms.

- New calibration tool compartment: positioning time the axis down = approximately 52 ms ± 2 ms, axis

up = 54 ms ± 2 ms.

Checking the offset

See "Adjusting the offset".

Reset the MA data to basic data (see table 10.3.4) and reference the axis.

Adjusting the offset

● Connect the axis testing device to the axis board. Select the axis on the axis testing device (2 or 3).

● Change the MA data for adjusting the offset using the values in the table 10.3.1.

Then reference the axis.

● Use the offset potentiometer on the servo board to set the axis position to 0 ± 1 digits.

● Check: the position display must not deviate from the value 0 by more than 1 digit.

Setting the speed

● Change the MA data for setting the tacho using the values in the table 10.3.2.

Then reference the axis.

● Set the axis testing device to time measurement (set the toggle switch to -1) and set the rotary switch for

axis 0 to 1.

● Start the axis in continuous mode. Distance: 0 to 2,800 digits.

● Increase the P gain on the servo board until the axis can be easily positioned.

● Use the tacho potentiometer on the servo board to set the end message signal to 119 ms ± 5 ms.

● Check: the positioning time must be 119 ms ± 5 ms (measured with a suitable P gain).

Adjusting the P gain

● Set the MA data as for setting the tacho.

● Start the axis in continuous mode. Distance: 0 to 2,800 digits.

● Use the ratio potentiometer on the servo board to increase the P gain until a slight tendency to vibrate can

be seen on the current curve.

● Increase/reduce the P gain until the position deviation no longer dips or rises (see Fig. 10.3.13 to Fig.

10.3.14).

● Use the tacho potentiometer on the servo board to adjust the speed to 119 ms ± 5 ms.

● Check: Start the axis in continuous mode. Distance: 0 to 2,800 digits.

- The P gain must be set so that the position deviation no longer dips or rises.

- For a distance of 0 to 2,800 digits, the positioning time must be 119 ms ± 5 ms.

Checking the positioning quality in accordance with table 10.3.4

● Reset the MA data to the basic data and reference the axis.

● Start the axis in continuous mode. Distance: 0 to 2,800 digits.

● 50 ms after the end signal, the position deviation must not exceed 2 digits.

Checking the offset

See "Adjusting the offset".

Reset the MA data to basic data (see Table 10.3.4) and reference the axis (all axes).
