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 for ... spindle modes other than the oscillation mode
...
Application Refer to DB31, ... DBX18.4 (oscillation controlled by the PLC)
example(s)
Special cases, If both of the interface signals are set simultaneously enabled, no oscillation speed is output.
errors, ......
If an interface signal is not set, then an oscillation speed is not output.
Corresponding to .... DB31, ... DBX18.4 (oscillation controlled by the PLC
DB31, ... DBX18.5 (oscillation speed)

DBX30.0 Spindle stop
Edge evaluation: yes
Signal state 1 or DB31, ... DBX30.0 (spindle stop)
edge change (corresponds to M5 spindle stop for master spindle).
0 → 1
Application A spindle stop is executed if the interface signal:
example(s) DB31, ... DBX61.4 (axis/spindle stationary) = 1
is signaled.
Corresponding to .... DB31, ... DBX17.6 (axis/spindle stationary)
DB31, ...
DBX30.1 Spindle start, clockwise rotation
Edge evaluation: yes
Signal state 1 or DB31, ... DBX30.1 (spindle start, clockwise)
edge change (corresponds to M3 spindle direction of rotation, clockwise for the master spindle)
0 → 1
Application With the positive edge of the starting signal "spindle start clockwise", the contents of the setting
example(s) data:
SD43200 $SA_SPIND_S
are read and become effective.
Corresponding to .... DB31, ... DBX18.7 (setpoint direction of rotation, counter-clockwise)
DB31, ... DBX18.6 (setpoint direction of rotation, clockwise)
DB31, ... DBX17.6 (invert M3/M4)
