6.3.5 Setting the Digital Rotary Encoder for the DP Axis

 Remove sleeve 1 and insert the star zero point gauge, in order to mechanically fix the star.

 Now, remove sleeve 4 or the sleeve 2 for the 6 segment C&P head as well and align the encoder.

 With the help of a parallel pin, set the rotary transducer of the DP - axis to 1.5 mm, parallel to the

glass pane of the segments.

6-11: Setting the Resolution on the Star Axis

Legend

1. The switch for the star axis resolution is

directly beneath the C&P head on the star

motor.

X Check the setting of this switch (1).

NOTE:

Only set the switch if the machine

power is off.

 HS-60, HS-50, S-27 HM, S-25 HM, S23 HM:

Switch position 10

 D, HF/HF3 and X machines: Switch position

NOTE:

Make sure that a 1.4 mm test probe can be easily passed through and that a probe with 1.6 mm

can not be passed through.

6-12: Measurement point for belt tension

NOTE:

The measurement point on the

measurement head should be in the

middle, between two deflection pulleys.

The measurement head should be kept

at a distance of maximum 2 - 3 mm

from the toothed belt.

Legend

1. Measurement point for the belt tension

X Hold the measuring head of the belt tension

measuring device in front of the toothed belt

(1) .

X Strike the toothed belt, to stimulate a vibration

of the toothed belt.

X If the belt tension frequency does not match

the value 280 Hz ±10 Hz, tension or relax the

belt via the drive motor fastening.

X Repeat these instructions until the belt tension

is correct.

C&P12 Adjusting the Stop for the Z Axis

228 Service Manual SIPLACE D4

6.3.7.2 General

From software version 601.01 onwards, during the reference run, the Z axis moves into the star position

with +/-6250/6750 digits downwards or up into the crank, to determine the Z axis zero point correction

factor. The prerequisite for this is the correct setting of the upper end position stop of the Z axis. This

ensures that the Z axis is in the center of the raceway and that the Z axis zero point can be correctly

determined.

Preconditions:

Before you begin adjustment work, check the belt tension and the correct installation of the belt lock at

the Z axis.

6.3.7.3 Settings

X Switch off the machine. This setting can be performed directly at the machine.

X The star gauge for setting the Z end stopper is mounted on the C&P head in exactly the same way

as the zero point gauge for the star.

X Remove segment 1 and rotate the star until the gauge pin fits into the segment guidance.

X For better access to the Z axis end stopper, unscrew the cable clamp at one side and turn it to the

side. Then carefully push the flat ribbon cable to the side.

ATTENTION:

Make sure that both ends of the tension

jack lie on the teeth of the toothed belt.

The star gauge ensures that the star is in the

correct position and that the Z axis is pressed

upwards.
