4) Stopping times at reversal points:
● OST1[oscillation axis] = stop time at reversal point 1 in [s]
● OST2[oscillation axis] = stop time at reversal point 2 in [s]
A stop time is entered into the appropriate setting data in synchronism with the block in the main
run and thus remains effective until the setting data is next changed.
The unit for the stop time is identical to the unit selected for the stop time programmed with G04.
5) Setting feedrate:
● FA[axis] = FValue
Positioning axis infeed.
The feedrate is transferred to the appropriate setting data in synchronism with the block in the
main run. If the oscillation axis is moved with reversal feed, the corresponding dependencies
must be indicated as described in Description of Functions V1.
6) Setting control settings for sequence of movements:
● OSCTRL[oscillating axis] = (set options, reset options)
The set options are defined as follows (the reset options deselect the settings):

Note
The option values 0-3 encode the behavior at reversal points at Power OFF. You can choose
one of the alternatives 0-3. The other settings can be combined with the selected alternative
according to individual requirements. A + character can be inserted to create a string of options.

Set/reset options
Meaning
Stop at next reversal point on deactivation of the oscillation movement (default). Can
only be achieved by resetting option values 1 and 2.
Stop at reversal point 1 on deactivation of the oscillation movement
Stop at reversal point 2 on deactivation of the oscillation movement
On deactivation of oscillation movement, do not approach reversal point unless
sparking-out strokes are programmed
Approach an end position after spark-out process
If the oscillation movement is aborted by delete distance-to-go, the sparking-out
strokes must then be executed and the end position approached (if programmed)
If the oscillation movement is terminated by deletion of distance-to-go, the program‐
med reversal point must be approached on deactivation of the oscillation movement.
Altered feedrate will only take effect from the next reversal point.
If feedrate setting is 0, path overlay is active, or otherwise velocity overlay
For rotary axis DC (shortest path)
Sparking-out stroke as single stroke
