Displayed times● ProgramPressing the softkey the first time shows how long the program has already been running.At every further start of the program, the time required to run the entire program the firsttime is displayed.If the program or the feedrate is changed, the new program runtime is corrected after thefirst run.● Program remainderHere you can see how long the current program still has to run. In addition, you can followhow much of the current program has been completed in percent on a progress bar.The first program execution differs in the calculation of the additional program executions.When a program is executed for the first time, the progress is estimated based on theprogram size and the actual program offset. The larger the program and the more linearthat it is executed, the more precise the first estimate. This estimate is very inaccurate asa result of the system for programs with steps and/or subprograms.For each additional program execution, the measured overall program execution time isused as basis for the program progress display.● Influencing the time measurementThe time measurement is started with the start of the program and ends with the end of theprogram (M30) or with an agreed M function.When the program is running, the time measurement is interrupted with CYCLE STOP andcontinued with CYCLE START.The time measurement starts at the beginning with RESET and subsequent CYCLESTART.The time measurement stops with CYCLE STOP or a feedrate override = 0.Counting workpiecesYou can also display program repetitions and the number of completed workpieces. For theworpiece count, enter the actual and planned workpiece numbers.Workpiece countCompleted workpieces can be counted via the end of program command (M30) or an Mcommand.Procedure1.
