W6: Path length evaluation

20.1

Brief description

Function
With the "Path length evaluation" function, the NCK specific machine axis data is made
available as the system and OPI variables, with whose help it is possible to assess the strain
on the machine axes and thereby make an evaluation on the state of the machine's
maintenance.
Recorded data
The following data is recorded:
• Total traverse path
• Total travel time
• Total travel count
• Total traverse path at high axis speeds
• Total travel time at high axis speeds
• Travel count at high axis speeds
• Total sum of jerks
• Axis travel time with jerk
• Travel count with jerk
Evaluation
When the function is activated, the selected control data is automatically sent and made
available via the system and OPI variables for evaluation in the part program or synchronized
actions, as with user-specified HMI functions.
Meaning
The data remains saved in the control, so that it may continue to be used after POWER OFF
/ ON. Consequently, the actual value of a data item represents the sum of all measured
values since the function was activated.
