Inspection and maintenance intervals
INFORMATION
The amount of wear depends on many factors and may be high. The system manu-
facturer must calculate the required inspection/maintenance intervals individually in
accordance with the project planning documents.
The following factors may lead to shorter inspection and maintenance intervals:
•
Number of real emergency switching off braking operations
•
Particularly high number of cycles with high motor acceleration
•
Especially high cyclic duration factor at high speed
•
Changing direction of rotation (reversing operation)
•
Vertical mounting positions and pivoted mounting positions
•
High mass moments of inertia due to the motion of the drive, e.g. in mobile drives
or drives subject to high impact and vibration load
•
Application-related retrodriving torques or torsional vibrations
•
External environmental influences, such as moisture, high degree of UV exposure,
low ambient temperatures.
9.3.1
Motor
The following table shows the inspection intervals for the motor:
Time interval
Activity
Design
Every 3000 hours of operation, at
least every 6 months
Check for possible bearing dam-
age in the event of running noise.
In the event of bearing damage,
have the bearing replaced by
SEW‑EURODRIVE Service or
specialists trained by
SEW‑EURODRIVE.

9.3.2
Brake
•
The brake does not require any maintenance.
•
You cannot measure the working air gap directly, since the brake is integrated in
the motor.
•
If the permissible total brake work W
insp
that was determined during configuration
has
been
reached,
you
must
have
the
brake
replaced.
Contact
SEW‑EURODRIVE.
•
The BK brake may only be replaced by SEW‑EURODRIVE.
