Installation sequence
WARNING
Damage due to uncontrolled magnetic attractive forces
The sequence specified in this introduction for the installation must be followed. Deviation from the se-
quence may result in dangerous situations and damage through magnetic forces.
Complete the installation of the machine bed, before installing the linear motor components. Mount and align
the rails and the graduated rule on the machine bed. Fit the bearings, buffers and required cables on the
carriage. Make sure the carriage moves properly.
Installation order:
1. Mount the magnet yokes on the support frame of the machine.
2. Mount the coil unit on the carriage.
3. Connect the cables to the coil unit.

Mounting the magnet yokes
NOTE
Damage due to contamination
The mounting surface must always be free from contamination. Particles with a size of more than 0.1 mm
can result in incorrect configuration and damage to your linear motor.
Start the assembly with yoke 1. Align yoke with 3 mm alignment pins or a milling reference. Mount the
magnet yokes on the support frames. Observe the maximum tightening torque
An axis reference for the magnetic yokes is achieved as follows:
• Alignment pins in the center yoke (for short distances)
• Alignment pins along the entire path (for longer distances)
• Milling reference along the entire path (inside radius < 0.2 mm) for longer distances
The other magnet yokes can then be mounted, whereby the mutual attractive force of the magnet yokes can
be controlled and utilized for the mechanical contact.
