2.3 Continuouspath mode, exact stop and LookAhead (B1)
2.3.1 Signals from channel (DB21, ...)
DB21, ...
DBX36.3
All axes stationary
Edge evaluation: no Signal(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
All axes assigned to the channel are stationary with interpolator end.
No other traversing movements are active.
2.3.2 Signals from axis/spindle (DB31, ...)
DB31, ...
DBX60.6
Position reached with exact stop coarse
Edge evaluation: no Signal(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
The axis is in the appropriate exact stop and no interpolator is active for the axis and:
• the control is in the reset mode (reset key or end of program)
• the axis was last programmed as a positioning axis or positioning spindle (initial setting of
supplementary axis: Positioning axis)
• the path movement was stopped with NC Stop
• the spindle is in the closed-loop positioncontrolled mode (SPCON/SPOS instruction) and is
stationary
• the axis is switched from closed-loop speedcontrolled to closed-loop positioncontrolled mode
with IS "position measuring system"
Signal state 0 or
edge change
1 → 0
The axis is not in the appropriate exact stop or the interpolator is active for the axis or:
• the path movement was stopped with NC Stop
• the spindle is in the closed-loop speedcontrolled mode (SPCOF/SPOSA instruction)
• the "followup" mode is active for the axis
• the "parking" mode is active for the axis
• the axis is switched from closed-loop positioncontrolled to closed-loop speedcontrolled mode
with IS "position measuring system"
Signal irrelevant for
...
Rotary axes that are programmed as rounding axes.
