Distance-to-go / Spindle reset
Signal(s) to axis / spindle (PLC → NCK)
Edge evaluation: Yes Signal(s) updated: Cyclic
Signal state 1 or edge

Independent of MD35040 SPIND_ACTIVE_AFTER_RESET selects a spin‐
dle reset for the various spindle modes in the following fashion:
Control mode:
●
Spindle stops
● Program continues to run
●
Spindle continues to run with subsequent M and S program commands
Oscillating mode:
● Oscillation is interrupted
● Axes continue to run
● Program continues with the actual gearbox stage
● With subsequent M value and higher S value, it is
● possible that IS "Setpoint speed limited" (DB390x DBX2001.1) is set.
Positioning mode:
● Is stopped
Signal state 0 or edge
change 1 → 0

Reference point values 1 to 4
Signal(s) to axis / spindle (PLC → NCK)
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 When the reference cam is reached, the NCK is signaled which coded ref‐
erence cam is actuated.
The IS must remain set until the reference point is reached or until a new
coded reference cam is approached.
If the machine axis has reached the reference point (axis stationary) then
reference
point value,
pre-selected via the IS from MD34100 is accepted as
new reference position in the control.
Signal state 0 No effect.
Signal irrelevant for ... Length measurement systems with distance-coded reference marks
Application On a machine tool with large traversing distances, four coded reference
cams can be distributed over the entire distance traveled by the axis, four
different
reference points approached and the time required to reach a valid
referenced point reduced.
Special cases, errors If the machine axis has reached the reference point and none of the four IS
are set, then reference point value 1 is automatically valid.
