Oscillation time
The oscillation time for oscillation mode can be defined in a machine date for each direction
of rotation:
Oscillation time in M3 direction
(referred to as t1 in the following):
MD35440 $MA_SPIND_OSCILL_TIME_CW
Oscillation time in M4 direction
(referred to as t2 in the following):
MD35450 $MA_SPIND_OSCILL_TIME_CCW
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.
