Oscillation via NCK
Phase 1:
NC/PLC IS:
DB31, ... DBX18.5 (Oscillation speed)
accelerates the spindle motor to the speed (with oscillation acceleration) defined in machine data:
MD35400 $MA_SPIND_OSCILL_DES_VELO (oscillation speed)
.
Start direction is defined through the following machine data:
MD35430 $MA_SPIND_OSCILL_START_DIR (Start direction with oscillation)
The time t1 (or t2) is started,
according to which start direction is given in the machine data:
MD35430 $MA_SPIND_OSCILL_START_DIR
The time - and not the fact that the oscillation speed is reached - is always decisive.
Phase 2:
If time t1 (t2) has passed, the spindle motor
accelerates in the opposite direction to the speed defined in machine data:
MD35400 $MA_SPIND_OSCILL_DES_VELO
.
Time t2 (t1) starts.
Phase 3:
If time t2 (t1) has passed, the spindle motor accelerates in the opposite direction (same direction as in Phase 1)
to the speed defined in machine data:
MD35400 $MA_SPIND_OSCILL_DES_VELO
.
Time t1 (t2) starts. The process continues with Phase 2.
Oscillation via PLC
NC/PLC IS:
DB31, ... DBX18.4 (Oscillation via PLC)
and
DB31, ... DBX18.5 (oscillation speed)
accelerates the spindle motor to the speed (with oscillation acceleration) defined in machine data:
MD35400 $MA_SPIND_OSCILL_DES_VELO (oscillation speed)
.
The direction of rotation is defined by NC/PLC IS:
DB31, ... DBX18.7 (Set direction of rotation CCW)
and
DB31, ... DBX18.6 (Set direction of rotation CW)
.
The oscillation movement and the two times t1 and t2 (for clockwise and counterclockwise rotation) must be
simulated on the PLC.
