descriptions.
Maintenance intervals
The table below shows the maintenance tasks which can be done by the end user.
The complete maintenance schedule is available on the Internet
(www.abb.com/drivesservices). For more information, consult your local ABB
Service representative (www.abb.com/searchchannels).
Maintenance and component replacement intervals are based on the assumption
that the equipment is operated within the specified ratings and ambient conditions.
ABB recommends annual drive inspections to ensure the highest reliability and
optimum performance.
Note: Long term operation near the specified maximum ratings or ambient
conditions may require shorter maintenance intervals for certain components.
Consult your local ABB Service representative for additional maintenance
recommendations.
