Application

The machine operating time since commissioning indicates the use of the machine. For
example, the mechanical wear and lubrication requirement for the shaft bearing of the
motors depend on the use hours.
If some motor is used for long duration runs, it might require frequent servicing, while for
a motor that is not used regularly the maintenance and service are scheduled less
frequently. The accumulated operating time of a motor together with the appropriate
settings for warning can be utilized to trigger the condition based maintenance of the
motor.
The operating time counter combined with the subsequent reset of the operating-time
count can be used to monitor the motor's run time for a single run.
Both the long term accumulated operating time and the short term single run duration
provide valuable information about the condition of the machine and device. The
information can be co-related to other process data to provide diagnoses for the process
where the machine or device is applied.
