Objective
Basic machine
Machine data
6-96
1. Simple series start-up during initial start-up
2. Inclusion of machine options (e.g. rotary tables or 2nd spindle)
3. Shortening of the start-up time
4. Simplification of the machine data handling in user displays for mechanics
and technicians making measurements
5. Standardized PLC program for the entire machine series
The following variations, e.g. for a milling machine with one or two rotary tables
or spindles are possible.
Starting from a basic variation
S
with three axes (X11,Y11,Z11),
S
magazine axis (B11),
S
spindle (C11)
a series start-up file is generated.
In the declaration of the machine data for this basic machine, all axes that might
be present as options are declared in the machine axis data.
This applies to one or two rotary tables (A11,A22) and/or a second spindle
(C22).
Because all the machine axes that are possible in the series are declared, all
the axis data modules are set up in the PLC (DB 31 – 38).
The axis assignment is the same whatever axes the machine has.
This is necessary for a standardized PLC program.
N10000 $MN_AXCONF_MACHAX_NAME_TAB[0]="X11"
N10000 $MN_AXCONF_MACHAX_NAME_TAB[1]="Y11"
N10000 $MN_AXCONF_MACHAX_NAME_TAB[2]="Z11"
N10000 $MN_AXCONF_MACHAX_NAME_TAB[3]="A11"
N10000 $MN_AXCONF_MACHAX_NAME_TAB[4]="A22"
N10000 $MN_AXCONF_MACHAX_NAME_TAB[5]="B11"
N10000 $MN_AXCONF_MACHAX_NAME_TAB[6]="C22"
N10000 $MN_AXCONF_MACHAX_NAME_TAB[7]="C11"
Machine data files are set up for individual machine options that then only
contain the changed machine data.
