Detailed descriptions of interface signals
4.8 Axis / spindle-specific signals
Signal state 1 or edge
change 0 → 1
Axes:
When being referenced, if the machine axis has reached the reference point
(incremental measuring systems) or the target point (for length measuring
system with distance-coded reference marks), then the machine axis is
referenced and the IS "Referenced / synchronized 2" (for position
measuring system 2) is set.
Spindles:
After "power-on", a spindle is synchronized the latest after one spindle
revolution (zero mark) or when passing the BERO.
Signal state 0 or edge
change 1 → 0
The machine axis / spindle with position measuring system 2 is not
referenced / synchronized.

Position reached with exact stop coarse
Signal(s) from axis / spindle (NCK → PLC)
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 The axis is in the appropriate exact stop and no interpolator is active for the
axis and
• the control is in the reset state (reset key or end of program).
• the axis was last programmed as a positioning spindle.
• the path motion was terminated with NC stop.
• the spindle is in position-controlled mode and is stationary.
• the axis is switched from closed-loop speed-controlled to closed-loop
position-controlled mode with IS "position measuring system".
Signal state 0 The axis is not in the appropriate exact stop or the interpolator is active for
the axis or
• the path motion was terminated with NC stop.
• the spindle is in the speed-controlled mode.
• the "parking" mode is active for the axis.
• the axis is switched-over from the position-controlled to the speed-
controlled mode with using the IS "Position measuring system".

Signal(s) from axis / spindle (NCK → PLC)
