P Performance of on/off-site work (commissioning, tests, measurements or other work)
R Replacement
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.
