Operation time
This is a function within the control system that keeps track of the amount of time the
"MOTORS ON" signal is active, i.e. the amount of time the robot is in the operating mode.
When the operation time limit for maintenance is reached, a message is displayed on the TPU.
How to access this is detailed in section
Reading the SIS output logsReading the SIS output
The following information is available about the operation time in the service routine.
Gearbox
Based on measurements, torque and RPM, for example, the system calculates an expected
service interval for each gearbox. When service is due, a message will be shown on the TPU.

The following information is available about the joint service status in the service routine.
The following information is available for the axis service status in the service routine.
