The smooth running characteristics and motor noise during operation have not changed.
When the motor is at a standstill, check the follows:
•
The motor foundation has no indentations or cracks.
•
The machine is aligned within in 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 (transverse forces) of the roller bearings are complied with.
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 (Page 96)" and "Maintenance (Page 99)".
