7.1 Important notes
NOTE
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 V3-mounting (shaft end upwards),
make sure that no liquids can enter the bearings. If an encapsulated assembly is required, please con-
sult our applications department beforehand.
• Ensure unhindered ventilation of the motors and observe the permissible ambient and flange tempera-
tures. For ambient temperatures above 40 °C please consult our applications department beforehand.
• Servomotors are precision devices.The flange and shaft are especially vulnerable during storage and as-
sembly.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 dam-
age to the ball bearings, shaft, holding brake and feedback System.
• Wherever possible, use only backlash-free, frictionally-locking collets or couplings. Ensure correct align-
ment of the couplings. A displacement will cause unacceptable vibration 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 shortens the life of the
Motor. Furthermore, it must be ensured that when using a collet, the motor shaft is degreased.
• 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, espe-
cially with small Motors.
• Check compliance the permitted radial and axial loads F
