9.3 Inspection and maintenance
Note
Inspection specifications
• Carefully comply with the relubrication intervals for rolling bearings that deviate from the
inspection intervals.
• When servicing a three-phase machine, it is generally not necessary to dismantle it. The
machine only has to be dismantled if the bearings are to be replaced.
9.3.3
First inspection after installation or repair
Perform the following checks after approximately 500 operating hours or at the latest six
months after commissioning:
Table 9-1
Checking
The electrical parameters are maintained.
The permissible bearing and winding temperatures are not exceeded.
The smooth running characteristics and machine running noise have not de‐
teriorated.
The foundation has no cracks or indentations. (*)
(*) You can perform these checks while the motor is running or at a standstill.
Additional tests may also be required according to the system-specific conditions.
NOTICE
Machine damage
When carrying out the inspection, if you detect any impermissible deviations from the normal
state, you must rectify them immediately. They may otherwise cause damage to the machine.
