3.6.3 SIS system parameters
General
This section details the system parameters that may be set with estimated values.
The values can be defined by the operating organization as knowledge of the
robot's working conditions are accumulated.
Since the counters are to be used for purposes defined by the user, ABB cannot
give any recommendations regarding their definitions.
Operation time limit (service level)
The number of operation hours selected as service interval.
E.g. by setting the value "20,000", the SIS will save this as the nominal time for
activating the alarm, not counting the percentage described below.
Operation time warning
A percentage of the "Operation time limit" specified above.
E.g. by setting the value "90", the SIS will alert the operator 18,000 hours after an
operation time "Reset" was made the last time.
Calendar time limit (service level)
The number of calendar years selected as service interval.
E.g. by setting the value "2", the SIS will save this as the nominal time for activating
the alarm, not counting the percentage described below.
Calendar time warning
A percentage of the "Calendar time limit" specified above.
E.g. by setting the value "90", the SIS will alert the operator after 90% of two years,
i.e. 657 days after a calendar time "Reset" was made the last time.
Gearbox warning
A percentage of the gearbox service interval as calculated by the system. E.g. by
setting the value "90", the SIS will alert the operator after 90% of the expected
service interval of each gearbox.
The robot system automatically detects and stores all required variables to calculate
the expected service interval (estimated remaining lifetime) of each gearbox. This
is done by extrapolating data from earlier operation into a function of time, using
a formula including:
• input and output torque
• gearbox spindle speed
• other variables
