Notes on individual functions
The following addresses allow asynchronized
oscillation to be activated and controlled from the
part program.
The programmed values are entered in the
corresponding setting data block-synchronizedly
during the main run and remain active until changed
again.
Activate, deactivate oscillation: OS
OS[axis] = 1:
Activate
OS[axis] = 0:
Deactivate
WAITP (axis):
•
If oscillation is to be performed with a geometry
axis, you must enable this axis for oscillation with
WAITP.
•
When oscillation has finished, this command is
used to enter the oscillating axis as a positioning
axis again for normal use.
Stopping times at reversal points:
OST1, OST2
Hold time Movement in exact stop area at reversal point
–2 Interpolation is continued without waiting for exact stop
–1 Wait for exact stop coarse
0 Wait for exact stop fine
>0 Wait for exact stop fine and then wait for stopping time
The unit for the stopping time is identical to the
stopping time programmed with G4.
Note
Oscillation with motion synchronized action and
stopping times "OST1/OST2"
When the stopping times have elapsed, the internal
block change takes place during oscillation (visible at
the new residual paths of the axes). When block
change has been completed, the deactivation function
is checked. During checking, the deactivation function is
defined according to the control setting for the
"OSCTRL" sequence of motions.
