Demounting
NOTICE
Product damage in the event of incorrect handling or falling down due to a change
in the centre of gravity when the motors are demounted.
Fasten the product to the mounting surface.
Or
Place the product with the underside of the Y-axis on a stable surface,
e.g. mounting table:
• Do not subject the Z-axis to stress.
• Secure the product to the bases to prevent tipping or falling.
WARNING
Risk of injury from electric shock, impact, crushing.
With motors demounted the weight of the Z-axis may cause it to move uncon-
trolled in the Y-direction and Z-direction.
• Before demounting the motors:
• Secure the Z-axis to prevent uncontrolled movements.
• Bring the Z-axis interface to the bottom end position.
1. Disconnect all cables from the motor.
2. Unscrew the 4 retaining screws on the motor.
3. Remove the motor.
4. Repeat steps 1. … 3. for the other motor.
Mounting
1. Position the motor flange and the motor.
2. Tighten the retaining screws.

Adjust motor cable outlets
WARNING
Risk of injury from electric shock, impact, crushing.
After unscrewing the motor retaining screws, the Z-axis interface drops to the
bottom end position.
• Make sure that the Z-axis interface is at the bottom end position.
The position of the motor cable outlets is factory-installed at the top mounting
position. The position can be adjusted to the installation situation by rotating the
motors in 90° steps.
Prerequisite: the product is secured to the mounting surface.

Procedure
Changing the cable outlets will result in loss of homing.
1. Position the Z-axis to ensure a range of movement of 10 cm in the Y-direction
to left and right.
2. Disconnect the cables from the motor if they are connected.
3. Unscrew the retaining screws on the motor.
4. Rotate the motor in the installed state in the direction shown to the desired
position:
–
Motor 1, left: clockwise
–
Motor 2, right: anticlockwise
For a rear motor attachment position:
The direction of rotation of the motors is identical with the directions shown
Ä
The Z-axis moves diagonally slightly upwards.
5. Tighten the retaining screws.
