Travel to fixed stop (F1)
5.2 Functionality
The width of the fixed stop monitoring window is set with the command FXSW[Machine axis
identifier] = <window width>. Unit: mm, inches or degrees - depending on the basic
measurement system, linear or rotary axis.
The commands are modal. The travel path and the command which activates the function
must be programmed in the same block
Note
The programming of the machine axis identifiers according to
MD10000 AXCONF_NAME_TAB is permitted for FXS... and should be used preferentially.
The machine axis identifiers according to MD20070 AXCONF_CHANAX_NAME_TAB are
permitted for FXS... provided this is assigned to precisely one axis - e.g. no rotation is
activated in the coordinate system.
Axis-specific setting data/machine data
If no monitoring window is programmed, the value from SD43520 FIXED_STOP_WINDOW
applies.
If a value is programmed, this is applied and adopted by the SD43520. Initially, the SD is
loaded using the value from MD37020 FIXED_STOP_WINDOW_DEF.
If no clamping torque is programmed, the value from SD43510 FIXED_STOP_TORQUE
applies.
If a value is programmed, this is applied and adopted by the SD43510. Initially, the SD is
loaded using the value from MD37010 FIXED_STOP_TORQUE_DEF.
The selection/de-selection of the function is made in the program via FXS[X1]=1 / =0 only.
This value is also written in SD43500 FIXED_STOP_SWITCH (travel to fixed stop selection).
