Functional sequence, programming, parameterization
Programming
Travel to fixed stop is selected or deselected with the following commands:
FXS[<axis>]=1
(select)
FXS[<axis>]=0
(deselect)
The commands are modal.
The clamping torque is set with command:
FXST[<axis>] = <torque>
The torque is specified as a percentage referred to the reference torque of the drive (SINAMICS: p2003).
The command is used for setting the width of the fixed stop monitoring window.
FXSW[<axis>] = <window width>
The unit is dependent on the default setting: mm, inch or degrees.
Channel axis identifier
Instead of the machine axis identifiers, it is also possible to use channel axis identifiers if the channel axis is
precisely assigned to one machine axis.
Restrictions:
Channel axis identifiers may not be used (option disabled) for machine axes which have an active transformation
or frame.
If the machine axis is a coupled axis (e.g. following axis), programming is prevented and alarm 14092 "Incorrect
axis type" is displayed.
The movement to the destination point can be described as a path or positioning axis movement. With
positioning axes, the function
FXS
can be performed across block boundaries. The function may also be selected
for several machine axes simultaneously. The
FXST
and
FXSW
commands are optional.
The travel path and the command which activates that function must be programmed in one block (exception:
Synchronized actions).
