Detailed descriptions of interface signals
4.8 Axis / spindle-specific signals
DB380x
DBX2.2
Distance-to-go / Spindle reset
Signal(s) to axis / spindle (PLC → NCK)
Edge evaluation: Yes Signal(s) updated: Cyclic
Signal state 1 or edge
change 0 → 1
Independent of MD35040 SPIND_ACTIVE_AFTER_RESET selects a
spindle 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

No effect
corresponding to ... MD35040 SPIND_ACTIVE_AFTER_RESET (own spindle reset)
IS "Reset" (DB3000 DBX0.7)
IS "Delete distance to go" (DB380x DBX2.2), another name applies for the
same signal, however, for an axis

DB380x
DBX2.4 - .7
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
reference 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.
corresponding to ... MD34100 REFP_SET_POS (reference point value)
MD36050 CLAMP_POS_TOL (clamping tolerance)
