Note:
•
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.
•
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.
Maintenance timers and counters
The control program has maintenance timers and counters that can be configured to
generate a warning when a pre-defined limit is reached. Each timer/counter can be
set to monitor any parameter. This feature is especially useful as a service reminder.
For more information, see the firmware manual.
