If the gear stage is to be changed (DB31, ... DBX82.3 (change over gear) is set), then the spindle
operating mode changes to the oscillation mode.
Depending on the instant in time that the interface signal:
DB31, ... DBX18.5 (oscillation speed)
is set, the spindle decelerates down to standstill with different deceleration levels:
The IS "Oscillation speed" is set before the interface signal:
DB31, ... DBX82.3 (change over gear)
is set by the NCK.
When oscillating, the spindle is decelerated down to standstill with the deceleration:
MD35410 $MA_SPIND_OSCILL_ACCEL.
Once the spindle is stationary, oscillation is immediately initiated.
The IS "Oscillation speed" is enabled after the IS "Change gear" is set by the NCK and when the
spindle is stationary. The position controller is disabled. The spindle decelerates with the specified
deceleration rate in the speed controlled mode.
After the IS "oscillation speed" is set, the spindle starts to oscillate with the oscillation acceleration
(MD35410).
if the interface signal:
DB31, ... DBX18.4 (oscillation via the PLC)
is not set, then automatic oscillation is executed in the NCK using the IS "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).
Signal state 0 or
edge change
1 → 0
The spindle does not oscillate.
Signal irrelevant for

... All spindle modes except the oscillation mode.
Application
example(s)
The oscillation speed is used to make it easier to engage a new gear stage.
