DBX16.0 - DBX16.2 Actual gear stage A to C
Corresponding to .... DB31, ... DBX82.0 - DBX82.2 (setpoint gear stage A to C)
DB31, ... DBX82.3 (change over gear stage)
DB31, ... DBX16.3 (gear stage is changed over)
DB31, ... DBX18.5 (oscillation speed)
Parameter sets for gear stages
DB31, ...
DBX17.6 Invert M3/M4
Edge evaluation: yes
Signal state 1 or The direction of rotation of the spindle motor changes for the following functions:
edge change
•
0 → 1
•
•
•
Application The machine has a selector switch to changeover between a vertical and a horizontal spindle. The
example(s) 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.
DB31, ...
Re-synchronize spindle when positioning 2 and 1
DBX17.4 - DBX17.5
Edge evaluation: yes
Signal state 1 When positioning, the spindle must be re-synchronized.
Signal state 0 or No effect.
edge change
1 → 0
Signal irrelevant ... Spindle modes other than the positioning mode.
for ...
Application The spindle has an indirect measuring system and slippage may occur between the motor and the
example(s) 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.
Corresponding to .... DB31, ... DBX60.4 (referenced/synchronized 1)
DB31, ... DBX60.5 (referenced/synchronized 2)
DB31, ...
DBX18.6 - DBX18.7 Setpoint direction of rotation, counter-clockwise/setpoint direction of rotation, clockwise
Edge evaluation: yes
Signal state 1 or If the interface signal:
edge change DB31, ... DBX18.4 (oscillation by the PLC)
0 → 1 is set, then the direction of rotation for the oscillation speed
can be entered using the two interface signals:
DB31, ... DBX18.6 - DBX18.7 (setpoint direction of rotation counter-clockwise and clockwise). The
times for the oscillation movement of the spindle motor are defined by setting the interface signals
"direction of rotation setpoint counter-clockwise and clockwise" for a corresponding length of time.
Signal irrelevant ... Spindle modes other than the oscillation mode.
