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
Positioning is realized using the instruction in
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.
