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
