Procedure for multi-channel controls
CHANDATA (channel number) for several
channels is only permitted in the file
N_INITIAL_INI.
N_INITIAL_INI
is the installation file with which
all data of the control is initialized.
Example:
%_N_INITIAL_INI
CHANDATA(1)
;Machine axis assignment channel 1
$MC_AXCONF_MACHAX_USED[0]=1
$MC_AXCONF_MACHAX_USED[1]=2
$MC_AXCONF_MACHAX_USED[2]=3
CHANDATA(2)
;Machine axis assignment channel 2
$MC_AXCONF_MACHAX_USED[0]=4
$MC_AXCONF_MACHAX_USED[1]=5
CHANDATA(1)
;axial machine data
;Exact stop window coarse:
$MA_STOP_LIMIT_COARSE[AX1]=0.2 ;Axis 1
$MA_STOP_LIMIT_COARSE[AX2]=0.2 ;Axis 2
;Exact stop window fine:
$MA_STOP_LIMIT_COARSE[AX1]=0.01 ;Axis 1
$MA_STOP_LIMIT_COARSE[AX1]=0.01 ;Axis 2
In the part program, the CHANDATA instruction
may only be used for the channel on which the NC
program is running, i.e. the instruction can be used
to protect NC programs from being executed
accidentally on a different channel.
Program processing is aborted if an error occurs.
Note
INI files in job lists do not contain any CHANDATA
instructions.
