Action instructions.
Consultation signals of the PLC associated with coordinate
latching.
The independent interpolator has a mark for each probe. Probe 1 will be the one assigned
to parameter PRBDI1 and probe 2 will be the one assigned to parameter PRBDI2.
PROBE1ACTIVE
PROBE2ACTIVE
The independent interpolator actives this mark when a latching process is active with the
indicated probe and it deactivates when there is no active latching process with the indicated
probe.
LATCH1ACTIVE(axis)
LATCH2ACTIVE(axis)
The independent interpolator actives this mark when activating a latching process on the axis
with the indicated probe and it deactivates when the latching process ends or it is canceled.
The latching process on the axis is canceled when the PLC activates the IRESET(axis) mark.
A reset of the channel cancels the latching processes on all axes of the channel.
Functions M02 and M30 will not be considered executed (done) until all the latching
processes active on the axes of the channel are finished.
LATCH1DONE(axis)
LATCH2DONE(axis)
The independent interpolator actives this mark when the latch event on the axis with the
indicated probe occurs; it deactivates it when activating a new latching process on the axis
with the same probe.
Variables related to coordinate latching.
The coordinate latching processes do not affect the variables associated with probing G100.
(V.)[ch].A.LATCH1.xn
Variable that can only be read from the program, PLC and interface.
Variable valid for rotary and linear axes.
The variable returns the execution value; reading it interrupts block preparation.
Machine coordinate obtained from latching probe 1 on the ·xn· axis.
Syntax.
·ch· Channel number.
·xn· Name, logic number or index of the axis.
(V.)[ch].A.LATCH2.xn
Variable that can only be read from the program, PLC and interface.
Variable valid for rotary and linear axes.
The variable returns the execution value; reading it interrupts block preparation.
Machine coordinate obtained from latching probe 2 on the ·xn· axis.
Syntax.
·ch· Channel number.
V.A.LATCH1.Z Z axis.
V.A.LATCH1.4 Axis with logic number ·4·.
V.[2].A.LATCH1.1 Axis with index ·1· in the channel ·2·.
