Consumption degree calculation function 54
[About the robot controller]
• When using this function by upgrading from a non-compatible controller
software version to a compatible controller software version, the consumption
degree during the period of the non-compatible software version is not added
up, thus the result of consumption degree calculation function cannot be the
correct value
• The consumption degree of the robot arm is saved in the robot controller, thus
it is necessary to use the correct combination of the robot arm and robot
controller.
To replace the robot arm or robot controller only, perform backup/restore of
predictive maintenance information to migrate the predictive maintenance
information.
(For backup/restore, refer to "11.3 Backup and restore".)
Depending on the operating status at startup, correct results may not be obtained
at the beginning due to fluctuations until sufficient data is accumulated.
Correctly set hand work conditions (weight, center of gravity, shape) actually used.
If the settings differ from the actual robot settings, the consumption degree cannot
be calculated correctly.
Use parameters HNDDAT* and WRKDAT* to set hand work conditions and use
Loadset commands to specify hand work conditions.
For details of hand work condition setting, refer to the separate "Instruction
Manual/Detailed Explanations of Functions and Operations".
When the predictive maintenance function is valid, the maintenance forecast is
not displayed and warning signals of maintenance forecast are not output. When
the information is reset by the predictive maintenance function or maintenance
forecast, the information in the other function is reset as well.
