Instead of the value for "Spindle override" the value of "feedrate override"
(DB380x DBB0) is used for the spindle.
The value of "spindle override" is used.
IS"Spindle override" (DB380x DBB2003)
IS"Feedrate override" (DB380x DBB0)
IS"Override active" (DB380x DBX1.7)
Function Manual Basic Functions V1
Re-synchronize spindle during positioning 1
Signal(s) to axis / spindle (PLC → NCK)
Signal(s) updated: Cyclic
When positioning, the spindle must be re-synchronized.
No effect
... spindle modes other than the positioning mode
The spindle has an indirect measuring system and slip may occur between
the motor and clamp. If the signal = 1, when positioning is started, the old
reference is deleted and the zero mark is searched for again before the end
position is approached.
IS "Referenced / synchronized 1" (DB390x DBX0.4)
Function Manual Basic Functions S1
Invert M3/M4
Signal(s) to axis / spindle (PLC → NCK)
Signal(s) updated: Cyclic
The direction of rotation of the spindle motor changes for the following func‐
tions:
● M3
● M4
● M5
● SPOS from the motion; not active for SPOS from standstill
The machine has a selector switch for a vertical and horizontal spindle. The
mechanical design is implemented so that for the horizontal spindle, one
more gearwheel is engaged than for the vertical spindle. The direction of
rotation must therefore be changed for the vertical spindle if the spindle is
always to rotate clockwise with M3.
Function Manual Basic Functions S1
Oscillation via PLC
Signal(s) to axis / spindle (PLC → NCK)
Signal(s) updated: Cyclic
If the IS "Oscillation via PLC" is set, then with the IS "Oscillation speed", a
speed is output in conjunction with the IS "Setpoint direction of rotation,
clockwise and counter-clockwise).
