With the following function, the spindle is in the control mode:
Spindle direction of rotation input M3/M4 or spindle stop M5
corresponding to ... IS "Active spindle oscillating mode" (DB390x DBX2002.6)
IS "Active spindle positioning mode" (DB390x DBX2002.5)

Spindle in position
Signal(s) from axis / spindle (NCK → PLC)
Edge evaluation: Yes Signal(s) updated: Cyclic
Signal state 1 or edge
change 0 → 1
Precondition for the output of IS "Spindle in position" is reaching the IS
"Exact stop fine". Additionally, the last programmed spindle position must
have been reached on the setpoint side.
If the spindle is already at the programmed position after a positioning, then
the signal "Spindle in position" is set.
Signal state 0 or edge
change 1 → 0
The IS "Spindle in position" is always reset when withdrawing IS "Exact stop
fine".
Application The interface signal is processed exclusively with the function spindle
positioning. This includes:
• SPOS, SPOSA and M19 in the part program
• SPOS and M19 in synchronized actions
Spindle in position for the tool change.
If the tool change cycle is interrupted by the machine operator e.g. with NC
stop, NC stop axis plus spindle, mode stop etc., then the correct position to
which the spindle is to travel in the tool changer can be queried using the IS
"Spindle in position".
Special cases, errors, ... If the spindle is traversed after a positioning for already set "Spindle in
position" signal, e.g. in the JOG mode, then this signal is deleted. If the
spindle returns to its original position in the JOG mode, then the signal
"Spindle in position" is set again. The last position selection is maintained.
