Writing of machine data

	The availability of this function depends on the configuration and the concrete scope of version

This command makes it possible to change in a part program axis specific machine parameters. The new values are valid program global. They are overwritten by the next update of machine data lists (e.g. startup of control).

	An eventually active path interpolation is stopped until the taking over of the new parameter is finished and the value has become effective. Eventually turning spindles are not stopped.

#MACHINE DATA [<mode>] [AX<name> | AXNR<expr>

<param_id><expr> | AXPARAM "<string>" [ WAIT ] ] (modal)

<mode> Synchronisation mode

Valid modes	Significance
---	Synchronization on decoding level (basic setting)
SYN	Synchronization on interpolation-(real time) level

AX<name> Name of the related axis or spindle for the new axis specific parameter value

AXNR<expr> Logical axis number of a channel axis or spindle for the new axis specific parameter value.Positiv integer.

Notice
No plausibility check as regards the logical axis number is conducted. The operator is solely responsible for making the correct entries.

<param_id><expr> Axis parameter in ISG-spelling (P-AXIS-xxxxx) with assigned new value in the unit of the parameter list [AXIS]. The following axis parameters can be changed by predefined keywords (param_id):

AXPARAM "<string>" Alternative syntax: Axis parameter with complete structure path and value in internal spelling of the parameter list [AXIS] (see example). All axis parameters can be changed

WAIT The use of this keyword is only allowed in connection with a synchronized setting (SYN) of an axis parameter. If a WAIT is programmed, additionally the program decoding is interrupted (implicit FLUSH) and it is waited, until the taking over of the new parameter is finished and the value has become effective in the whole NC channel.

WAIT can not be used during contour modifying functions like e.g. active tool radius compensation, polynomial contouring, or HSC-mode.
