Replacement R
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.
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.
