Maintenance Schedule - ABB IRB 120 Product Manual

3.2.2. Maintenance schedule

General
The robot, consisting of robot and controller cabinet, must be maintained regularly to ensure
its function. The maintenance activities and their respective intervals are specified in the table
below.
Non-predictable situations also give rise to inspections of the robot. Any damages must be
attended to immediately!
The inspection intervals do not specify the life of each component.
Activities and intervals, standard equipment
The sections referred to in the table can be found in the different chapters for every
maintenance activity.
The table below specifies the required maintenance activities and intervals:

1)
"Regularly" implies that the activity is to be performed regularly, but the actual interval may
not be specified by the robot manufacturer. The interval depends on the operation cycle of the
robot, its working environment and movement pattern.
Generally, the more contaminated environment, the shorter intervals. The more demanding
movement pattern (sharper bending cable harness), the shorter intervals.
2)
Battery low alert (38213 Battery charge low) is displayed when remaining backup capacity
(robot powered off) is less than 2 months. Typical lifetime of a new battery is 36 months if
the robot is powered off 2 days/week or 18 months if the robot is powered off 16 h/day. The
lifetime can be extended (approx. 3 times) for longer production breaks by a battery shutdown
service routine. See Operating manual - IRC5 with FlexPendant for instructions..
