Removal / Installation
The drive motor (1) of the lifting axis is located behind the front cover. If the drive motor is
disconnected from the power supply, the drive is fixed with a brake.
CAUTION
Do not move the motor against the brake
Do not move the lifting axis motor shaft against the brake. This could impair the braking function or
damage the brake.
➢ Loosen the two motor support fastening screws (2) sealed with locking varnish.
➢ Loosen (do not remove) the tensioning screw (5) on the tensioning device. This relaxes the
drive toothed belt.
➢ Loosen and remove the 2 fastening screws (2) and then remove the toothed belt (3).
➢ Loosely fix the motor support and drive motor into the installation position, with the 2
fastening screws (2).
➢ Run the new drive toothed belt around the two toothed wheels and tension (pretension) the
toothed belt at the slot provided, with the help of the motor support.
➢ Set the final belt tension. To do this, tension the drive toothed belt at the tensioning device,
with the help of the tensioning screw (5). This moves the motor support accordingly in the
slots.
⇨
Setting value: Set the belt tension to 235 Hz.+/- 10 Hz.
➢ Tighten the 2 fastening screws (2) on the motor support, check the belt tension and adjust
where necessary.

3.4.2 Replace the Feed Axis Drive Motor
Spare Part:
When replacing the drive motors of the WPC5 and WPC 6, it is, with immediate effect,
necessary to take note of the version / item number of the motor, as the successors are not
100% compatible.
Because it is not permitted to install a mixture of new motors in a WPC, the old drives continue
to be available as replacements!
As a result of this incompatibility, the version of the entire WPC was changed when the new
drives were introduced.
Overview
(1) Feed axis motor, compl.
(2) Tensioning screw
(3) 2 x motor support fastening
screws
(4) Toothed belt for the drive
(5) Deflection pulley
(6) 4 x drive motor fastening screws
(7) Electrical connections
