Maintenance intervals
If installed in an appropriate environment, the drive requires very little maintenance. The
table below lists the routine maintenance intervals recommended by ABB. The
recommended maintenance intervals and component replacements are based on
specified operational and environmental conditions.
Note: Long-term operation near the specified maximum ratings or environmental
conditions may require shorter maintenance intervals for certain components.
The tables below contain user tasks. For tasks to be performed by ABB and more details
on the maintenance, consult your local ABB Service representative. On the Internet, go to
