• Switch the WPC off at the main switch.
• Unplug from the power supply and secure the WPC to prevent unauthorized reactivation.
Refer to the WPC operating manual for details.
• Undock the WPC from the SIPLACE machine and move it to a suitable position for service
work.
The drive motor (6) of the lifting axis is located
behind the front cover (1). If the drive motor is
disconnected from the power supply, the drive is
fixed with a brake.
• Remove the front cover(1).
• Remove the two side covers (2) + (3).
• Loosen the 4 fastening screws in each case and
remove the two bottom hand guards (4) + (5).

3.3.2 Replacing the Lifting 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.
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
The drive motor (3) 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.
➢ Unscrew the electrical connections (1) + (2).
