Final Work
Align the driver unit (see "3.4.4.1 Align the Driver Unit" [ 3-24]).
Check the belt tension (see "3.4.6 Setting the Feed Axis Belt Tension" [ 3-28]).
The two ends of the toothed belt must be inserted
into the clamping unit (2) so that the clamping unit
teeth engage with the belt teeth. The two ends must
meet (1).
Note the length of the new toothed belt. The toothed
belt is 2120 mm long/ number of teeth: 424.
If the belt is too long, shorten it to the correct length.
Fit the driver unit onto the clamping unit (2). While
doing this, tighten the 4 fastening screws
"crosswise" with a torque of 1.3Nm.

Push the driver unit fully into the tower.
Push the two setting gauges (1) + (2) under the toothed belt, at a distance of 360 mm.
The teeth of the toothed belt (3) must lie on the setting gauge.
Press the large setting gauge downwards with a suitable object or with your finger, so that
the toothed belt lies on the gauge (5).
Adjust the belt tension. To do this, gently pull the toothed belt or tap it with an Allen wrench,
so that it starts swinging and then measure the value with the belt tension measuring device.
Setting value: The belt tension must be 90 Hz +/-5 Hz.
