Mechanical installation
Perform all work with the greatest care and without hurrying.
Flange mounting
The following table provides information on components for mount-
ing the motor on the machine / system:
Motor Bore dia. [mm] Cheese-head
screw DIN EN ISO
4762, 8.8
Tightening torque
[Nm]
AM202x 4.5 M4 3
AM204x 5.6 M5 6
Output elements
Secure moving parts against ejection
Make sure there are no moving parts on or in the machine during
operation. Feather keys [+] are only secured during transport.
Unsecured parts can be ejected from the machine during opera-
tion and cause serious or fatal injuries.
Protect the motor from inadmissible load
Avoid bending components during transport or handling and do
not change any insulation distances. Avoid hard shocks to the
shaft end, the ball bearings or the feedback system. Furthermore,
note vibration qualities and vibration resistance. If necessary, pro-
vide additional support for the motor.
An impermissible load on the components can have a negative ef-
fect on the performance of the motor. Impacts on the motor shaft
impair the concentricity of the motor.
Ensure adequate earthing via the protective conductor
The thermal connection of the motor flange determines the power
loss.
Ensure adequate earthing via the protective conductor or the mo-
tor flange.
Bearing load during instal-
lation
Avoid mechanically overdetermined support of the motor shaft
through rigid coupling and additional external support.
When mounting output elements, care must be taken that the load
on the shaft and bearings due to shear forces, such as radial force
F
R
and axial force F
A
, is low. Axial loads shorten the service life and
can lead to malfunctions of the holding brake [+].
Special features when using toothed belt drives:
The radial loads on the shaft must not be exceeded when using a
toothed belt drive. The motor shaft may suffer a fatigue fracture due
to excessive alternating loads. Please pay attention to chapter:
"Technical data", [Page16].
