DB31, ... DBX18.5 (oscillation speed)
The spindle is in oscillation mode if a new gear step was defined using automatic gear step selection (M40) or
M41 to M45 (DB31, ... DBX82.3 (Change gear) is set).
NC/PLC IS:
DB31, ... DBX82.3 (Change gear)
is only enabled when a new gear step is defined
that is not the same as the current actual gear step.
If NC/PLC IS:
DB31, ... DBX18.5 (Oscillation speed)
is simply set by the PLC without a new gear step being defined by the NC,
the spindle does not change to oscillation mode.
Oscillation mode is activated with NC/PLC IS:
DB31, ... DBX18.5 (Oscillation speed)
.
Depending on NC/PLC IS:
DB31, ... DBX18.4 (Oscillation via PLC)
while the function is in operation, a distinction is made between:
• Oscillation via NCK
• Oscillation via PLC
• Oscillation with FC18

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
