3.18 Oscillation
3.18.1 Asynchronous oscillation (OS, OSP1, OSP2, OST1, OST2, OSCTRL, OSNSC,
OSE, OSB)
An oscillating axis travels back and forth between two reversal points 1 and 2 at a defined
feedrate, until the oscillating motion is deactivated.
Other axes can be interpolated as desired during the oscillating motion. A continuous infeed
can be achieved via a path movement or with a positioning axis, however, there is no
relationship between the oscillating movement and the infeed movement.
Properties of asynchronized oscillation
● Asynchronous oscillation is active on an axis-specific basis beyond block limits.
● Block-oriented activation of the oscillation movement is ensured by the part program.
● Combined interpolation of several axes and superimposing of oscillation paths are not
possible.
Programming
The following commands can be used to activate and control asynchronous oscillation from the
part program.
The programmed values are entered in the corresponding setting data with block
synchronization during the main run and remain active until changed again.
Syntax
OSP1[<axis>]=<value> OSP2[<axis>]=<value>
OST1[<axis>]=<value> OST2[<axis>]=<value>
FA[<axis>]=<value>
OSCTRL[<axis>]=(<setting option>,<reset option>)
OSNSC[<axis>]=<value>
OSE[<axis>]=<value>
OSB[<axis>]=<value>
OS[<axis>] = 1
OS[<axis>] = 0
Meaning
<axis>: Name of oscillating axis
OS: Activate/deactivate oscillation
Value: 1 Switch oscillation on
0 Switch oscillation off
OSP1: Define position of reversal point 1
