Note
Adapt the inspection to the plant-specific conditions.
Further tests are also necessary in line with the component documentation or corresponding
to the particular system-specific conditions.
Test scope
While the motor is running, check that
● the electrical parameters are maintained.
● the smooth running characteristics and motor noise during operation have not changed.
When the motor is at a standstill, check that
● the motor foundation has no indentations or cracks.
● the machine is aligned within the permissible tolerance ranges.
● all of the mounting bolts/screws for the mechanical and electrical connections are tight.
● the insulation resistance of windings lies in the permissible tolerance range.
● any bearing insulation is fitted in accordance with the labeling.
● cables and insulating parts and components are in a good condition and are not
discolored.
● the permissible radial forces (cantilever forces) of the roller bearings are complied with.
Note
The permissible radial forces are listed in Catalog NC 62, D 21.4 and in the Configuration
Manual "SIMOTICS M-1PH8 main motors".
NOTICE
Machine damage when ignoring abnormalities identified during the inspection
Abnormalities identified during inspection that are subsequently ignored can result in
machine damage.
• Analyze and remove any abnormalities identified, taking into consideration Chapters
"Faults" and "Maintenance".
