Installing a servo geared motor with foot mounting

NOTICE
Servo geared motor damage resulting from impermissible housing loads on uneven
mounting footprints
If the servo geared motor is put under stress when tightening the fixing screws, this can result
in functional faults and gearbox damage.
• Carefully ensure that the mounting footprint is flat.
• Clean the mounting footprint before starting any work.
• Calculate the foundation for the servo geared motor in accordance with the weight and
torque. Take account of the forces acting on the servo geared motor.
• Ensure that the foundation for the servo geared motor is torsionally rigid.
• Construct the foundation in such a way that no resonance vibration occurs and no vibration
is transmitted from adjacent foundations.
• If the servo geared motor is fastened to a concrete foundation, use foundation blocks for the
appropriate recesses.
• Align and grout the slide rails into the foundation.
• Align the servo geared motor carefully and without offset with the units on the input and
output side. Take into account the elastic deformation due to operating forces.
• Prevent shift from external forces due to lateral impact.
• Use stud bolts or headless screws of property class 8.8 or higher for foot mounting. Observe
the tightening torque.
