MAINTENANCE
All the components of the VSD have definite lifetimes that decrease significantly when their operating temperatures increase. These are some typical component lifetimes for a drive operating well within its design rating and ambient temperature between 0 and 40°C:
The lifetime of all VSD components as well as bearings and insulation system drops sig- nificantly when the operating temperature increases. It is essential to maintain the ambient temperature within the acceptable range to achieve high reliability and longevity of this equipment.
