SetProfilPosition at position change
If bit 3 is set in C01297
, the setpoint positions at the MCKInterface are automatically accepted into
the profile with the applied profile number if a change of data is detected at the corresponding
input for the setpoint position.
• If the "0: dnPosOut_p=dnPosIn_p" mode has been set in C01296/1
for converting the position,
automatic acceptance is executed if the incremental position selection at the dnPosIn_p input
was changed.
• If another mode (>0) has been set in C01296/1
, automatic acceptance is executed if the
incremental position selection at the wPosUnitsLW and wPosUnitsHW inputs was changed.
• From version 11.00.00 a hysteresis can be set in C01245/3
for the position change.
PosExecute at position change
(from version 11.00.00)
If bit 4 is set in C01297
, an automatic "PosExecute" takes place if the incremental position selection
changes and this change is higher than set in the hysteresis for position change (C01245/3
).
If the selection is made in units, so that in a first step it has to be converted into increments, and if
this automatic function is then activated, the "PosExecute" will only be created automatically when
the internal conversion is completed (bPosSetDataValid).
Tip!
This option serves to start travel requests very easily by simply defining the new target
position.
8.3.1.2 Operating mode change with profile number
One of the operating modes of the LS_MotionControlKernel system block can be assigned to the
positioning profiles via the four subcodes of C01298
:
• When a changeover to the corresponding profile is carried out, the set operating module is
requested at the same time.
• With the setting "0: Op.Mode inputs", no operating modes are changed when the profile is
changed. Instead, the operating mode requested "externally" applies (optionally via the inputs
wInMckPosCtrl_1, wOperationMode or bOperationMode_1...8 of the FB L_MckCtrlInterface
).
Note: These inputs are internally connected via OR-logic. Only connect one of these inputs to
ensure non-ambiguous operating mode changeovers!
