Detailed Description
2.1 General functionality
Channel axis identifier
Instead of the machine axis identifiers, it is also possible to use channel axis identifiers if the
channel axis identifiers are assigned exactly to one machine axis.
Restrictions:
Channel 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).
Examples
With machine axis identifiers:
X250 Y100 F100 FXS[X1]=1
X250 Y100 F100 FXS[X1]=1 FXST[X1]=12.3
X250 Y100 F100 FXS[X1]=1 FXST[X1]=12.3 FXSW[X1]=2
X250 Y100 F100 FXS[X1]=1 FXSW[X1]=2

Channel axis identifier with unambiguous machine axis assignment:
For the purpose of illustrating the differences in programming, chanel axis X is programmed
as the image of machine axis AX1 [or X1 (Name in machine parameter:
MD10000 $MN_AXCONF_MACHAX_NAME_TAB)]
.
Programming with machine axis identifiers
FXS[X1] = 1
FXST[X1] = 10
FXSW[X1] = 5
Programming with channel axis identifiers
FXS[X] = 1
FXST[X] = 10
FXSW[X] = 5
