Travel to fixed stop (F1)
5
Note
This function is not available with version T/M value.
5.1 Brief description
Application range
The travel to fixed stop (FXS = Fixed Stop) function can be used to establish defined forces
for clamping workpieces, such as those required for sleeves and grippers. The function can
also be used for the approach of mechanical reference points. With sufficiently reduced
torque, it is also possible to perform simple measurement operations without connecting a
probe.
Travel to fixed stop can be performed simultaneously for several axes and parallel to the
movement of other axes.
The fixed stop can be approached on a path (straight line, circle).
Availability
The "travel to fixed stop" function is available when MD37000 FIXED_STOP_MODE (travel
to fixed stop mode) = 1 is set. The function can then be started from the NC program with
command "FXS[x]=1".
5.2 Functionality
Programming
Travel to fixed stop is selected with command
● FXS[machine axis identifier] = 1 selected.
● FXS[machine axis identifier] = 0 de-selected.
The clamping torque is set with the command:FXST[Machine axis identifier] = <torque>. It is
given as a percentage of the static torque of the drive or a percentage of the nominal motor
torque for MSD.
