Create initialization program at an external PC
The data area identifier and the data type identifier can be used to determine the areas, which
are to be treated as a unit when the data are saved:
_N_AX5_TEA_INI
_N_CH2_UFR_INI
_N_COMPLETE_TEA_INI
When the control is started up initially, a set of data is automatically loaded to ensure proper
operation of the control.
Procedure for multi-channel controls (CHANDATA)
CHANDATA(<channel number>) for several channels is only permissible in the file
_N_INITIAL_INI. This is the commissioning file with which all data of the control is initialized.

$MC_AXCONF_MACHAX_USED[2]=3

$MC_AXCONF_MACHAX_USED[1]=5

$MA_STOP_LIMIT_COARSE[AX1]=0.2
$MA_STOP_LIMIT_COARSE[AX2]=0.2

$MA_STOP_LIMIT_FINE[AX1]=0.01
CHANDATA statement
In the part program, the CHANDATA instruction may only be set for that channel in which the
NC program is executed; i.e. the instruction can be used to protect NC programs so that they
are not executed in the wrong channel.
Program processing is aborted if an error occurs.
Note
INI files in job lists do not contain any CHANDATA instructions.
