6.3 Mounting the motor
Axial kit EAMM-A
Tab. 1: Overview of 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.
2. Fasten motor mounting kit, observe instructions è www.festo.com/sp.
3. Fasten the motor without tension. Support large and heavy motors.
Connect motor cables only on completion of mounting.
6.4
Mounting axis
Requirement
–
No collision in the movement space of the attachment component with motor,
mounting and sensor components.
–
Sufficient space to reach maintenance interfaces.
–
Sufficient space for reaching and securing the sealing air connection.
–
Flatness of the mounting surface of 0.05 %of the stroke length or maximum
0.5 mm over the stroke length of the bearing surface.
–
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 the maximum tightening torque and screw-in depth.
In the case of planar and 3-dimensional 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 component
Requirement:
–
No collision in the movement space of the attachment component with motor,
mounting and sensor components.
–
Flatness of the mounting surface of the attachment component of 0.01 mm
above the slide surface.
–
Minimise breakdown torque with force Fx. Short lever arm a from the centre of
the guide
to the centre of gravity of the attachment
–
The maximum screw-in 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 the maximum tightening torque and screw-in depth.
When using an additional guide axis or external guide, ensure that the axes and
guide are aligned exactly parallel.
Recommendation: use guide mountings with tolerance compensation.

6.6 Mounting accessories
Requirement
–
No collision in the movement space of the attachment component with motor,
mounting and sensor components.
–
Protection against uncontrolled overtravel of the end positions.
–
Referencing to reference switch or end position.
–
Query of end positions or intermediate positions.
1. Select accessories è www.festo.com/catalogue.
2. Mount the sensor (reference or query):
–
Mount the sensor bracket and switch lug (depending on the type of
mounting).
–
Mount the sensor.
Instruction manuals è www.festo.com/sp.
Sensor bracket and switch lug
–
Switch lug: mounting on slide
–
Sensor bracket: mounting via profile groove
–
Protect the sensor from external magnetic or ferritic influences (e.g. min. 10 mm distance to slot
nuts).
–
Preferably use hardware limit switches with normally closed function (protection guaranteed even
in case of sensor failure).
–
Query switching lug only with inductive sensor.
–
Query integrated magnets in the slide only with magneto-resistive sensor.

Tab. 6: Overview of sensor mounting
Connecting sealing air
The use of overpressure or negative pressure in the range of approx. ± 0.02 MPa
(± 2.9 psi; ± 0.2 bar) reduces or prevents the following contamination:
–
The application of negative pressure minimises the release of abraded particles
into the environment.
–
Applying overpressure reduces the penetration of dirt into the drivetrain.
Fig. 3: Connecting sealing air
1. Remove the sealing air plug screw from the threaded hole.
2. Mount the screw fitting and connect the hose.
