Protect the motor from unacceptable stresses. During transport and handling no com-
ponents must be damaged.
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 consult Kollmorgen beforehand.
Ensure an 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. Ensure that there is adequate heat transfer in the sur-
roundings and the motor flange.
Motor flange and shaft are especially vulnerable during storage and assembly - so avoid
brute force. It is important to use the locking thread which is provided to tighten up cou-
plings, 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.
Wherever possible, use only backlash-free, frictionally-locking collets or couplings.
Ensure correct alignment of the couplings. A displacement will cause unacceptable vibra-
tion and the destruction of the bearings and the coupling.
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).
Take note of the no. of motor poles and the no. of resolver poles, and ensure that the cor-
rect 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.
Avoid axial loads on the motor shaft, as far as possible. Axial loading significantly short-
ens the life of the motor.
Check the compliance to the permitted radial and axial forces F
