Axial distance-to-go for oscillation infeed in BCS
(Distance to end, pendulum, baseCoor) (real)
Axial distance-to-go for oscillation infeed in PCS
(Distance to end, pendulum, workpieceCoor) (real)
Path distance-to-go for oscillation infeed in BCS
(not P2) (Distance to end, pendulum, baseCoor)
(real)
Path distance-to-go for oscillation infeed in PCS
(not P2) (Distance to end, pendulum,
workpieceCoor) (real)
(Path parameter normalized) (real)
Normalized path parameter: 0 for beginning of
block to 1 for end of block
Drive utilization (for 611D only)
Drive effective power in W (for 611D only)
Drive torque setpoint in Nm (for 611D only)
Actual current value of the axis (for 611D only)
Flag variables: can be used to build complex
conditions in synchronous actions:
8 Markers (Index 0 - 7) are available.
Reset sets the markers to 0.
Example:
WHEN .....DO $AC_MARKER[0]=2
WHEN .....DO $AC_MARKER[0]=3
WHEN $AC_MARKER[0]==3 DO $AC_OVR=50
Can be read and written independently of
synchronous actions in the part program:
IF $AC_MARKER == 4 GOTOF SPRUNG
Floating-decimal parameter for synchronous
actions. Serves as intermediate saving and
evaluation in synchronous actions.
50 Parameters (Index 0 - 49) are available.
Current oscillation reversal points 1 and 2:
The current setting data from
$SA_OSCILL_REVERSE_POS1 or
$SA_OSCILL_REVERSE_POS2 is read.
This enables setting data changes at the reversal
positions during active oscillation, i.e. during an
active synchronous action.
