ABB IRB 4400/60 - 3.3 Maintenance schedule

3.3 Maintenance schedule
3.3.1 Specification of maintenance intervals
Introduction
The intervals are specified in different ways depending on the type of maintenance
activity to be carried out and the working conditions of the IRB 4400:
• Calendar time: specified in months regardless of whether the system is
running or not.
• Operating time: specified in operating hours. More frequent running means
more frequent maintenance activities.
• SIS: specified by the robot's SIS (Service Information System). A typical
value is given for a typical work cycle, but the value will differ depending on
how hard each part is run. The SIS used in M2000 and M2000A is further
described in the section Service Information System, M2000 on page 127.
The SIS used in M2004 is further described in the Operating manual - Service
Information System.
