6.4.6 Belt tension Z-axis

Please Note:

The measuring point of the measuring pin must be in the middle of the two deflection pulleys.

The measuring pin should be at a maximum distance of 2 - 3 mm, from the toothed belt. 6

(1) Measurement point for the belt tension

➠ Attach the measuring head in front of the toothed belt (1) .

➠ Strike the toothed belt, to reach a stimulation of vibration of the open ended toothed belt.

➠ Stretch the belt over the fastening of the driving motor (compare: service manual) if the

frequency of the belt tension does not reach a value of

280 Hz + 10 Hz.

➠ Repeat these instructions until the belt tension is correct.

6.4.7 Adjusting the Stop for the Z-Axis

6.4.7.1 Tools and Equipment

– Set of DIN 911 Allen keys

– Gauge for Z-limit stop, item no.03019865-01

6.4.7.2 General

With the softwareversion 503.02 and higher the calculation of the zero point correction of the

Z-axis is done with the star in a position of 2700 digits. During the reference run the Z axis (star

axis position +2700 digits) now moves down and up into the aperture. To ensure that the Z axis is

located correctly in the center of the raceway/aperture, it must be possible for the Z axis to move

into the aperture up to the limit stop. This is only possible if the Z limit stop is set correctly.

Preconditions: 6

Before you start with the setting please check the followings:

– Belt tension Z-Axis

– Correctly mounted clamping device on the Z-axis belt.

Fig. 6.4 - 15 Clamping device Z-axis

You ensure, so that the clamping device is firmly fixed between the teeth of the drive belt.

6.4.7.3 Settings

➠ Switch off the machine. The setting can, however, be made directly on the machine.

➠ The star gauge for setting the Z limit stop is mounted on the C&P head in exactly the same way

as the zero point gauge for the star.

➠ Remove the segment 1 from the star and turn the star, so that the gauge pin is inserted on

segment 1.

Fig. 6.4 - 16 Z-Limit stop gauge mounted

Please Note:

For DLM 1 heads an additional adapter must be mounted for the gauge.

– The star gauge ensures that the star is at the correct position and the Z axis is pushed up-

wards.

➠ To obtain better access to the Z limit stop, you should unscrew the cable clip on one side and

twist it away. Push the ribbon cable carefully aside.

➠ Use the 5/100 mm feeler gauge to check that it can be moved freely (without resistance) bet-

ween the Z limit stop and the clamp. (Fig. 6.4 - 17)

If this is not the case, the limit stop must be adjusted.
