Derating in case of deviating ambient conditions

A permanent use of the motors is possible when
the specified class 3K22 according to EN IEC
60721-3-3:2019 is observed. Deviations and
enhancements according to the follwing table
must be observed.

8.3.1 Vibration load during opera-
tion
Vibrations are sine-wave oscillations in stationary
use, which vary in their effect on the resistance of
the motors depending on their intensity.
The specified limit values are valid for frequen-
cies of 10‑2000 Hz during stimulation on the
motor flange. Limitations can be necessary for
occurring resonances depending on the applica-
tion and installation situation.
The following limit values apply according to
EN 60068-2-6 for MS2N motors:

Check the vibration load on the fan housing in
case of forced ventilation. The specified values
must not be exceeded.
8.4 Operation
During operation, keep the ambient and opera-
tion conditions and technical data specified in
the project planning manual.
Checks during operation:
•
Pay attention to exceptional noise.
•
Pay attention to increased vibrations.
•
Check the motors and fan units for cleanli-
ness.
•
Check the tightness of the coolant connec-
tions.
•
Check the monitoring devices and diag-
nostic / error messages of the controllers.
Decommission the drive when deviations from
normal operation exist. For further procedure
refer to .
