Example: Spindle Positioning - Siemens SINUMERIK 828D Function Manual

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.

Main program
Programming
PROC MAIN
...
N210 COUPON(S2,S1)
N220 SPOS[1]=100
...
N310 G01 F1000 X100 M19
Replacement subprogram "LANG_SUB", version 1
Optimized for simplicity and velocity by directly addressing the spindles (S1: Leading spindle, S2: Following
spindle).
Programming
N1000 PROC LANG_SUB DISPLOF SBLOF
N2100 IF($P_SUB_AXFCT==2)
N2110 ;Replacement of SPOS/SPOSA/M19 for active synchronous spindle coupling
N2185 DELAYFSTON
N2190 COUPOF(S2,S1)
N2200
N2210 IF($P_SUB_SPOS==TRUE) OR ($P_SUB_SPOSA==TRUE)
N2220 ;SPOS and SPOSA are mapped to SPOS
Basic Functions

K1: Mode group, channel, program operation, reset response
Meaning
Replace positioning commands
motion
Meaning
Spindle position for M19 = 260
Position approach mode for M19:
"Approach in the positive direction
(ACP)"
Comment
; Activate synchronous spindle coupling
; Position leading spindle with SPOS
; Position leading spindle with M19
Comment
; Start stop delay area
; Open synchronous spindle coupling
; Position leading and following spindles
