If the IS "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 into MD35440 and MD35450.
Application If the new gear stage cannot be engaged in spite of several oscillation at‐
tempts by the NCK, the system can be switched to oscillation via the 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 stage is reliably
changed - even with unfavorable gear wheel positions.

Signal state 1 If the gear stage is to be changed (IS "Change gear stage" (DB390x
DBX2000.3)
is set), then the spindle operating mode changes to the oscilla‐
tion mode.
Depending on the instant in time that IS "Oscillation speed" is set, the spindle
brakes down to standstill with different acceleration levels:
1. The IS "Oscillation speed" is set before the IS "Change gear stage" is set
by the NCK. The spindle is braked down to standstill with the acceleration
when oscillating (MD35410). Oscillation starts immediately once the
spindle is stationary.
2. The IS "Oscillation speed" is set after the IS "Change gear stage" is set
by the NCK and after the spindle is stationary. The position controller is
disabled. The spindle is braked with the acceleration in the speed
controlled mode. After the IS "Oscillation speed" is set, the spindle starts
to oscillate with the oscillation acceleration (MD35410).
If the IS "Oscillation via the PLC" (DB380x DBX2002.4) is not set, then au‐
tomatic oscillation is executed in the NCK using the IS "Oscillation speed".
The two times for the directions of rotation are entered into MD35440 and
MD35450.
If the IS "Oscillation via PLC" is set, then with the IS "Oscillation speed", a
speed is output in conjunction with the IS "Setpoint direction of rotation,
clockwise and counter-clockwise).
Signal state 0 The spindle does not oscillate.

Application The oscillation speed is used to make it easier to engage a new gear stage.
