Alarm suppression after new programmingTravel to fixed stop can be used for simple measuring processes.For example, it is possible to carry out a check for tool breakage by measuring the tool lengthby traversing onto a defined obstacle. To do so, the fixed stop alarm must be suppressed.When the function for clamping workpieces is then used "normally," the alarm can be activatedusing part program commands.6.2.9 Travel with limited torque/force FOCFunctionUsing the "Force Control" function to traverse with limited torque/force, when traversing, themaximum permissible torque/force can be limited to a percentage of the maximum possibleaxis torque. The limit value can be changed at any time, also while the axis is traversing. Thechanges can be realized in the interpolator clock cycle, dependent on distance, time or on anyother variable. The "Force Control" function can also be programmed in synchronized actions.The function can be permanently activated, or block related.ProgrammingSyntaxFOCON[]FOCOF[]FOC[]MeaningParameter MeaningFOCON: Activate torque/force limitingFOCOF: Deactivate torque/force limitingFOC: Activate non-modal torque/force limiting: Channel axis name, type: AXISExampleProgram code CommentN10 FOCON[X] ; Modal activation of the torque limitN20 X100 Y200 FXST[X]=15 ; X travels with reduced torque (15%)N30 FXST[X]=75 X20 ; Changing the torque to 75%,N40 FOCOF[X] ; Disable torque limitF1: Travel to fixed stop6.2 Detailed descriptionBasic FunctionsFunction Manual, 01/2015, 6FC5397-0BP40-5BA2 311
