11.2 Asynchronous oscillation

Control methods
Oscillation movements can be controlled by various methods:
● The oscillation movement and/or infeed can be interrupted by delete distance-to-go.
● The reversal points can be altered via NC program, PLC, HMI, handwheel or directional
● The feedrate velocity of the oscillation axis can be altered through a value input in the NC
● The oscillation movement can be controlled entirely by the PLC.
Methods of oscillation control
There are two modes of oscillation:
1. Asynchronous oscillation:
2. Oscillation by synchronized movement actions:
11.2 Asynchronous oscillation
Characteristics
The characteristics of asynchronous oscillation are as follows:
● The oscillation axis oscillates backwards and forwards between reversal points at the
● Linear interpolation G01 is active for the oscillation axis regardless of the G code
● Asynchronous oscillation is active on an axis-specific basis beyond block limits.
● Several oscillation axes (i.e. maximum number of positioning axes) can be active at the

program, PLC, HMI or via an override. The feedrate can be programmed to be dependent
on a master spindle, rotary axis or spindle (revolutional feedrate).

Is active across block boundaries and can also be started from the PLC/HMI.
In this case the asynchronous oscillation and an infeed movement are coupled via
synchronized actions. In this way, it is possible to program oscillation with infeed at the
reversal points which is active on a non-modal basis.

appropriate response to a supplementary condition. If the oscillation axis is not positioned
at reversal point 1 when the movement is started, then it traverses to this point first.
