Brief description

12.1
Definition
When the "Oscillation" function is selected, an oscillation axis oscillates backwards and
forwards at the programmed feedrate or a derived feedrate (revolutional feedrate) between
two reversal points. Several oscillation axes can be active at the same time.
Oscillation variants
Oscillation functions can be classified according to the axis response at reversal points and
with respect to infeed:
● Asynchronous oscillation across block boundaries
● Oscillation with continuous infeed.
● Oscillation with infeed in both reversal points or only in the left-hand or right-hand
● Sparking-out strokes after oscillation.
● Beginning and end of oscillation at defined positions.
Response at reversal points
The change in direction is initiated:
● without the exact stop limit being reached (exact stop fine or coarse)
● after reaching the programmed position or
● after the programmed position is reached and expiry of a dwell.
● by an external signal (from the PLC).

During reciprocating movement, other axes can interpolate at will. The oscillation axis can
act as the input axis for dynamic transformation or as the master axis for gantry or
coupled-motion axes. Oscillation is not automatically linked to the AUTOMATIC mode.
Simultaneous infeed in multiple axes is possible. However, there is no interpolative
connection between the infeed and oscillation movements.
reversal point. The infeed can be initiated at a programmable distance from the reversal
point.
