7.3.2

Checking the toothed belt pretensioning

Requirements
For motors with brake:
• When checking before commissioning: the motors are demounted

6.6.2 Mounting.

• When checking after commissioning: the motor brakes are released.

Fig. 27: Checking toothed belt pretensioning, EXCH-40 as an example

Y-axis (cross-brace)

X-axis 1 with energy chain

Motor-side drive cover

Belt tension setting piece

X-axis carriage

Procedure
1. Place the belt tensioning setting piece on X-axis 1 with energy chain between the drive cover and

the X-axis carriage.

The slot of the belt tensioning setting piece is intended for attaching and fixing to the profile of
the X-axis.
The toothed belt pretensioning can be inspected with the profile cover of the X-axis in place or
removed.
