9.15 Replacing functions by subprograms
Basic Functions

9.15.3.6 Example: Spindle positioning
In the subprogram, only the replacement of commands SPOS and SPOSA is explicitly executed. Additional
replacements should be supplemented in essentially the same fashion.
Parameterization
Main program
Replacement subprogram "LANG_SUB", version 1
Optimized for simplicity and velocity by directly addressing the spindles (S1: Leading spindle, S2: Following
spindle).
Machine data Meaning
MD30465 $MA_AXIS_LANG_SUB_MASK[AX5] =
'H0002'
Replace positioning commands
MD22080 $MC_AUXFU_PREDEF_SPEC[9] = 'H0021' Output of M19 to the PLC before
motion
Setting Data Meaning
SD43240 $SA_M19_SPOS[AX5] = 260 Spindle position for M19 = 260
SD43250 $SA_M19_SPOSMODE[AX5] = 4 Position approach mode for M19:
"Approach in the positive direction
(ACP)"
