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).

➢
Loosen the two motor support fastening screws (4) 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 drive motor with motor
support. Make sure that the drive toothed belt is not buckled or damaged.
➢ Remove the toothed belt.
➢ Mark the installation position of the drive motor on the motor support.
➢ Loosen the 4 drive motor fastening screws (4) on the motor support.
➢ Fit the new drive motor with the 4 fastening screws (4) to the motor support. Observe the
original installation position.
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.

Installation
➢ Loosely fix the motor support and drive motor into the installation position, with the 2
fastening screws (2).
➢ Reconnect the electrical connections with the motor. When fitting, note that there is an anti-
twist lock (notch) present. Tighten the connection appropriately.
➢ Run the drive toothed belt around the motor pinion and the spindle toothed wheel 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 235Hz +/- 10Hz.
➢ Tighten the 2 fastening screws (2) on the motor support, check the belt tension and adjust
where necessary.
➢ Seal the 2 fastening screws (2) with locking varnish.
➢ Calibrate the lifting axis..
