7.1 Important notes
Attention
Motor damage
• Take care, especially during transport and handling that components are not bent and
that insulation clearances are not altered.
• The site must be free of conductive and aggressive material. For V3­mounting (shaft
end upwards), make sure that no liquids can enter the bearings. If an encapsulated as­
sembly is required, please consult our applications department beforehand.
• Ensure unhindered ventilation of the motors and observe the permissible ambient and
flange temperatures. For ambient temperatures above 40 °C please consult our appli­
cations department beforehand.
• Servomotors are precision devices.The flange and shaft are especially vulnerable dur­
ing storage and assembly.It is important to use the locking thread which is provided to
tighten up couplings, gear wheels or pulleys and warm up the drive components, where
possible.Blows or the use of force will lead to damage to the ball bearings, shaft, hold­
ing brake and feedback System.
• Wherever possible, use only backlash­free, frictionally­locking collets or couplings. En­
sure correct alignment of the couplings. A displacement will cause unacceptable vibra­
tion and the destruction of the ball bearings and the coupling.
• For toothed belts, it is vital to observe the permissible radial forces. An excessive radial
load on the shaft will significantly shorten the life of the Motor.
• Avoid axial loads on the motor shaft, as far as possible. Axial loading significantly short­
ens the life of the Motor.
• In any case, avoid creating a mechanically constrained motor shaft mounting by using a
rigid coupling with additional external bearings (e.g. in a gearbox).
• Take note of the no. of motor poles and the no. of resolver poles and ensure that the
correct setting is made in the used servo terminals. An incorrect setting can lead to the
destruction of the motor, especially with small Motors.
• Check compliance the permitted radial and axial loads F

belt drive, the minimum permitted diameter of the pinion follows from the equation:
