3.2 Functional principle
Two fixed stepper motors drive a toothed belt arrayed in an H-shape.
The toothed belt moves the Y-axis (traverse) and the slide located on the Y-axis (traverse) in a 2-dimen
sional space. A controller calculates the position of the slide. The controlled interaction of the motors
results in the corresponding movement of the slide.

Fig. 4.5
5. Use the lifting gear to position the product on the mounting points of the mounting surface
(è Fig. 4.1).
If mounting kits are covered by the Y-axis (traverse), this can be moved manually. To do
this, remove the motors (è 4.5.4 Dismantling/mounting motors) or release the holding
brake.
If mounting points are covered by the energy chain, this can be detached
(è 4.5.3 Attachments on the energy chain).
6. Position the product in such a way that the elongated holes of the mounting kits are located cent
rally over the prepared mounting points. Reposition the mounting components if necessary
(è 4.5.1 Positioning mounting components).
7. Secure the X-axes with screws and washers. The X-axes must be able to be moved.

8. If present:
Remove the labelled transport restraints
(cable ties) from the moving parts.
9. Remove the transport restraints and transport lugs with support plates (è Fig. 4.4, page 14).
Note
Keep reusable transport restraints and the corresponding screws for future use (main
tenance, dismantling).
10.For motor attachment underneath: Mount loose covers with the supplied shorter screws (M5 x 40)
(tightening torque 8.3 Nm).

è X-axis 2 is aligned.
4.4.4 Aligning X-axes parallel with each other
1. Loosen all of the screws of the adjusting kits one after the other on X-axis 2 by a ¼ turn. When do
ing this, apply counter pressure to the adjusting bolts to prevent them from turning.
2. Manually move the Y-axis (traverse) back and forth over the entire stroke of the X-axes to establish
the parallelism of the X-axes (è 4.5.2 Manually moving the Y-axis (traverse)).
3. Move the Y-axis (traverse) to the motor side. Tighten the screws of the adjusting kit located at this
position of X-axis 2 (tightening torque 24 Nm).
4. Move the Y-axis (traverse) to the next adjusting kit. Tighten the screws of the adjusting kit located
at this position of X-axis 2 (tightening torque 24 Nm).
5. Repeat the process for all of the other adjusting kits on X-axis 2.

Eliminating warping in the product
Note
Warping in the product can result in malfunctions and increased wear and thus a re
duced service life.
1. Loosen each of the 8 screws 4 on the side of
X-axis 2 1 by 1 turn.
2. Manually move the Y-axis (traverse) 2 back
and forth over the entire X-stroke to eliminate
warping (è 4.5.2).
3. Unscrew a screw 4, secure with Loctite 243
adhesive and screw tight immediately (tight
ening torque 5.9 Nm).
4. Repeat this process for all screws 4.
4.4.5 Checking the toothed belt pretension
Note
Incorrect toothed belt pretensioning can damage the product. Possible consequences:
– Reduced service life of the toothed belt, guides and ball bearings
– Altered performance of the product
– Impaired positioning accuracy
– Position errors and risk of collision caused by skipping of the toothed belt
Remedy: Check and adjust the toothed belt pretensioning in the following cases:
– After installing the product for the first time
– After the initial commissioning phase (after approx. 30 strokes at operating temper
ature)
– After removal/installation or replacement of the toothed belt
31442
Fig. 4.16
The toothed belt pretensioning can be inspected with mounted or dismounted profile
cover of the X-axis.
Use an acoustic frequency meter to check the toothed belt pretensioning.

1. During initial start-up:
Remove motors with holding brake
(è 4.5.4 Dismantling/mounting motors).
After commissioning:
Release holding brake.
2. Place the belt tension setting piece 4 on the
guide rail 2 between the drive cover (motor
side) 3 and carriage 5.
3. Slide the Y-axis (traverse) 1 with the carriage
against the belt tension setting piece.
è The distance dimension of 144.4 mm (L11)
for checking is set.
4. Align the probe 8 underneath the belt ten
sion setting piece 4 in the middle of the
toothed belt 7. When doing this do not touch
the toothed belt.

4678
Fig. 4.18
Note
The toothed belt must be able to vibrate freely and must not touch the probe of the
frequency measurement device. For evaluation of the toothed belt pretension, perform
several measurements to balance out any measurement tolerances.
5. Make the toothed belt vibrate by hitting it once with a slim, heavy object (e.g. an Allen key 6).
6. Read the self-generated frequency of the toothed belt on the frequency meter. The measured value
must be in a frequency range of 150 … 160 Hz.
è If the measured value is within this tolerance range, the toothed belt has the correct pretension.
è If the measured value is outside this tolerance range, the toothed belt pretensioning must be
adjusted.

4.4.6 Setting the toothed belt pretension
Note
The toothed belt pretensioning diminishes during storage and operation. This is normal
and must not be changed by increasing the tension of the toothed belt. The reduced
pretension is not suitable for evaluating the level of wear of the toothed belt.
1. Unscrew the 2 threaded pins 1.
è The locking element of the belt tensioning
device is released.
Note
Clockwise rotation of the adjusting screws will increase the tension and frequency of
oscillation of the toothed belt.
Anti-clockwise rotation of the adjusting screws will reduce the tension and frequency of
oscillation of the toothed belt.
1
Fig. 4.19
2. Change toothed belt pretensioning by evenly
turning the 2 adjusting screws 2.
3. Move or travel the Y-axis (traverse) once over
the entire stroke of the X-axis. This causes the
toothed belt to fully settle and equalises dif
ferences in tension.

4. Check the toothed belt pretensioning
(è 4.4.5 Checking the toothed belt pretension).
Repeat this process until the measured value is
within the specified frequency range.
5. Secure the toothed belt pretensioning by
screwing in the 2 threaded pins 1
(tightening torque 1 Nm).
6. Pull out belt tension setting piece.

Note
Within the framework of the initial start-up phase, check the toothed belt tension again
after 30 strokes (è 4.4.5 Checking the toothed belt pretension) and adjust if necessary
(è 4.4.6 Setting the toothed belt pretension).
7. Mount the profile covers of both X-axes (tightening torque 1 Nm) (è 4.4.1 Mounting profile covers).
8. Secure the energy chain to the retainers with the screws and nuts
(tightening torque 2.9 Nm) (è 4.5.3 Attachments on the energy chain).
Use Loctite 243 adhesive.
9. For motors with holding brake: Mount drive motors of the X-axes
(è 4.5.4 Dismantling/mounting motors)
4.5 Optional work
4.5.1 Positioning mounting components
The mounting components are supplied pre-positioned. If required, these may be moved within the
mounting tolerance.
1. Prepare threaded holes in the mounting surface
(è Fig. 4.1) and (è Tab. 4.1).
2. Loosen hexagon head screws 3 half a turn.
3. Position the mounting component 2

4.5.2 Manually moving the Y-axis (traverse)
The Y-axis (traverse) can be moved manually for mounting and alignment purposes. The Y-axis (tra
verse) is secured against uncontrolled movements with transport restraints (cable ties) when delivered.
1. Remove the labelled transport restraints (cable
ties) from the moving parts.
2. For motors with holding brake: Remove motors (è 4.5.4 Dismantling/mounting motors).
3. Manually move the Y-axis (traverse) to the desired position.
