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.
