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

NOTE
At the rear of the control module on WPCs with new motors, a jumper must be fitted to
connector X29ag (changed motors) in addition to jumper X28ag (detection of 45 mm
component height).
Additional Information
The incompatibilities relate to the temperature sensors on the motors.
Minimum Firmware version 40A (WPCHNG_0051040A.BHX) is required to operate the new
motors in the WPC5 / WPC6.
Firmware Version 40A is available as of station software SIRIO 710.0.
If a "WPC5 900-950mm / Standard" [03067619-04], or a "WPC6 900-950mm" [03067618-04]
with new motors is to be fitted to a SIPLACE placement machine with a version of the SIRIO
software < 710.0, you should note the following:
- Any prompt by the station software to download the WPC firmware must be ignored.
- The station software must be upgraded to a version ≥ 710.0.
- If an earlier version of the WPC firmware is (inadvertently) downloaded, the WPC stops and
a temperature error message is issued.
Removal / Installation
➢ Unscrew the electrical connections (7).

NOTICE
Screw joints difficult to loosen
Each screw joint has an O-ring seal. This can make opening the screw joint difficult.
Use a pair of water pump pliers to help you unscrew the connection.
Make sure that the O-rings do not fall out of the screw joint and that they are not damaged.
When refitting, grease the thread and the O-rings with a little Vaseline.
