13.1 Important Notes
Only qualified staff with knowledge of mechanical engineering are permitted to assemble
the motor.
Always assemble motors in a voltage-free state; i.e. no operating
voltages of any components of the system may be switched on.
There is a risk of death or severe injury from touching exposed contacts.
Ensure that the switch cabinet remains turned off (barrier, warning signs
etc.). The individual voltages will only be turned on again during setup.
— Protect the motor from unacceptable stresses. During transport and handling no
components 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
applications department beforehand. Ensure that there is adequate heat transfer in
the surroundings and the motor flange, so that the maximum permissible flange tem-
perature of 65°C is not exceeded in S1 operation.
— 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 couplings, gear wheels or pulley wheels and warm up the drive compo-
nents, 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
vibration 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 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.
— Avoid axial loads on the motor shaft, as far as possible. Axial loading significantly
shortens the life of the motor.
— Check the compliance to the permitted radial and axial forces F
