Important Notes
l
Servomotors are precision equipment. The flange and shaft are especially vulnerable
during storage and assembly — so avoid brute force. Precision requires delicacy. It is
important to use the locking thread which is provided to tighten up couplings, gear
wheels or pulley wheels and warm up the drive components, where possible. Blows
or the use of force will lead to damage to the bearings and the shaft.
l
Wherever possible, use only backlash-free, frictionally-locking collets or couplings.
Ensure correct alignment of the couplings. A displacement will cause unacceptable
vibration and the destruction of the bearings and the coupling.
l
For toothed belts, it is vital to observe the permissible radial forces. An excessive ra-
dial load on the shaft will significantly shorten the life of the motor.
l
Avoid axial loads on the motor shaft, as far as possible. Axial loading significantly
shortens the life of the motor.
l
In all cases, do not create a mechanically constrained motor shaft mounting by using
a rigid coupling with additional external bearings (e.g. in a gearbox).
l
For mounting style V3 (shaft end upwards), make sure that no liquid can enter the up-
per bearing.
l
Take note of the no. of motor poles and the no. of resolver poles, and ensure that the
correct setting is made in the servo amplifier which is used. An incorrect setting can
lead to the destruction of the motor, especially with small motors.
