7.3 Mounting the motor
Fig. 3 Motor mounting
Only loosen screws or threaded pins that are described in the directions in the
instruction manual.
1. Select the motor and motor mounting kit from
Festo è www.festo.com/catalogue.
When using other motors: observe the critical limits for forces, torques and
velocities.
Fig. 4 Remove the plug screw
2. Remove the sealing air plug screw from the threaded hole.
3. Fasten motor mounting kit, observe instructions
è www.festo.com/sp.
4. Fasten the motor without tension. Support large and heavy motors.
Connect motor cables only on completion of mounting.
7.4 Fasten axis
High mechanical loads on the mounting connections
If the mounting position of the motor and the mounting component simultan­
eously cause high rectified torques around the longitudinal axis, this leads to high
mechanical loads at the mounting interfaces.
•
The foot mounting HPE should only be used in combination with the profile
mounting MUE or the slot nuts NST.
Requirement
–
No collision in the movement space of the attachment component with motor,
mounting and sensor components.
– Sufficient space to reach maintenance interfaces.
– Flatness of the mounting surface of 0.05% of the stroke length or max.
0.5 mm over the stroke length of the bearing surface.
– Required support points lie within the specified support
distances
è 14.2 Characteristic curves.
– No distortion or bending when installing the product.
1. Select mounting attachments
è
www.festo.com/catalogue.
2. Place the mounting attachments on the support points.
3. Tighten retaining screws.
Observe max. tightening torque and max. screw­in depth.
For area and 3­dimensional gantries, pay attention to parallelism, product height
and alignment of the axes.
For additional information, contact your local Festo Service.

Tab. 3 Requirement for attachment element
Requirement
–
No collision in the movement space of the attachment component with motor,
mounting and sensor components.
– Flatness of the mounting surface of the mounting component of 0.01 mm
(recirculating ball bearing guide KF/roller guide RF) or 0.03 mm (plain­bearing
guide G) over the slide surface.
– Position of the centre of gravity and tilting moment (force F parallel to the axis
of motion) of the attachment component centrally on the slide and close to
the slide surface (short lever arm a).
– The maximum screw­in depth of the retaining screws is not exceeded.
1. Select accessories è www.festo.com/catalogue.
2. Place centring components in centring holes.
3. Position the attachment component on the slide.
4. Tighten retaining screws.
Observe max. tightening torque and max. screw­in depth.
When using an additional external guide, ensure exact parallelism and alignment
of the axes and guide.
Recommendation: use guide fixings with tolerance compensation.
