DB31, ...
DBX18.4
Oscillation controlled by the PLC
Edge evaluation: yes
Signal(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
If the interface signal:
DB31, ... DBX18.4 (oscillation controlled by thePLC)
is not set, then automatic oscillation in the NCK is carried-out using the interface signal:
DB31, ... DBX18.5 (oscillation speed).
The two times for the directions of rotation are entered in the machine data:
MD35440 $MA_SPIND_OSCILL_TIME_CW (oscillation time for the M3 direction)
and
MD35450 $MA_SPIND_OSCILL_TIME_CCW (oscillation time for the M4 direction).
If the IS "oscillation via PLC" is set, then with the IS "oscillation speed" a speed is only output in
conjunction with the interface signals:
DB31, ... DBX18.6 - DBX18.7 (setpoint direction of rotation, counter-clockwise and clockwise).
The oscillation, i.e. the continuous change of the direction of rotation, is performed by the PLC user
program using the interface signal "setpoint direction of rotation, counter-clockwise and clockwise"
(oscillation via the PLC).
Application
example(s)
If the new gear stage cannot be engaged in spite of several attempts by the NCK, the system can
be switched to oscillation via PLC. Both of the times for the directions of rotation can then be
altered by the PLC user program as required. This ensures that the gear satge is reliably changed -
even with unfavorable gear wheel positions.
