Example
For an active synchronous spindle coupling between the leading spindle S1 and the following
spindle S2, the following replacement cycle to position the spindle is called using the SPOS
command in the main program.
Positioning is realized using the statement in N2230:
SPOS[1]=GP($P_SUB_SPOSIT,$P_SUB_SPOSMODE)
SPOS[2]=GP($P_SUB_SPOSIT,$P_SUB_SPOSMODE)
The position to be approached is read from the system variable $P_SUB_SPOSIT; the position
approach mode is read from the system variable $P_SUB_SPOSMODE.
