Parameter: Address extension
The "address extension" of an auxiliary function is for addressing different components of the
same type. In the case of predefined auxiliary functions, the value of the "address extension"
is the spindle number to which the auxiliary function applies.
If no address extension is programmed, the address extension is implicitly set = 0. Auxiliary
functions with the address extension = 0 always refer to the master spindle of the channel.
Example
Programming Function
N10 M3
; "Spindle right" for the master spindle of the channel
N20 M0 = 3
; "Spindle right" for the master spindle of the channel
N30 M1 = 3
; "Spindle right" for the 1st spindle of the channel
N40 M2 = 3
; "Spindle right" for the 2nd spindle of the channel
Grouping together auxiliary functions
To assign an auxiliary function for all spindles of a channel to the same auxiliary function
group, the value "–1" is entered for the "address extension" parameter.
Example:
For all the spindles of the channel, the auxiliary function M3 (machine data index = 6,
corresponding to the table in the Section "Predefined Auxiliary Functions") is assigned to the
second auxiliary function group.
MD22040 $MC_AUXFU_PREDEF_GROUP[ 6 ] = 2
MD22050 $MC_AUXFU_PREDEF_TYPE[ 6 ] = "M"
MD22060 $MC_AUXFU_PREDEF_EXTENSION[ 6 ] = -1
MD22070 $MC_AUXFU_PREDEF_VALUE[ 6 ] = 3
Parameter: Value
The parameters "value" and "type" define the meaning of an auxiliary function, i.e. the
system function that is activated on the basis of this auxiliary function. The "value" cannot be
changed for a predefined auxiliary function. For some predefined auxiliary functions, the
"value" can be reconfigured via additional machine data (see Section "Associated Auxiliary
Functions").
