1.1

Activate the probe.

The CNC can have configured two probes. Before any probing move, the CNC must know
which is the active probe, or, which is the same, which of the two probes it must attend to.
It is selected via part-program or MDI using the instruction #SELECT PROBE.

Programming.

When programming this instruction, you must define which probe is active and whether it's
active high or low.

Programming format.

The programming format is the following; the list of arguments appears between curly
brackets and the optional ones between angle brackets.

#SELECT PROBE [<{probe}><, {pulse}>]

Although both parameters are optional, at least one of them must be programmed.

Probe number. Which is probe 1 and which probe 2?

The names of the probes are set in the order they have been defined in the machine
parameters. The CNC assumes as first probe the one connected to the input indicated in
machine parameter PRBDI1 and as second probe the one connected to the input indicated
in machine parameter PRBDI2.

Logic level to activate probe; high (5 V / 24 V) or low (0 V).

Changing the default activation level reverses the operation of functions G100 and G103.
When changing the probe logic activation level, G100 makes a movement until the probe
stops making contact and G103 makes a movement until the probe makes contact. Since
probing canned cycles use functions G100 and G103, changing the logic activation level also
changes the operation of the canned cycles accordingly.

The logic activation level indicates whether the probe operations are active high (24V or 5
V) or active low (0V) of the signal provided by the probe. Programming the logic activation
level is optional because each probe has been assigned one by default.

The logic activation level of each probe by default is set in the machine parameters
(parameters PRBPULSE1 for probe ꞏ1ꞏ and PRBPULSE2 for probe ꞏ2ꞏ) and it depends on
the connection between the probe and the CNC.

Properties of the instruction and influence of reset, turning the
CNC off and of the M30 function.

The instruction #SELECT PROBE is modal. The probe and the selected logic activation level
stays active after an M02 or M30 and after an error or a reset. On power-up and after
validating the machine parameters, the CNC activates probe ꞏ1ꞏ and initializes the logic
activation level of both probes with the values set in the machine parameters.

If a probing move is executed without activating the probe, it will not send any signal to the CNC when
it makes contact. This can cause the probe to break because the probing move will not be stopped.

{probe}

Optional. Number of probe to activate.

If not programmed, the CNC uses the active probe.

{pulse}

Optional. Logic level to activate probe. The CNC uses the high level with
"POS" and the low level with "NEG".

If not programmed, the CNC uses the default probe activation level.

#SELECT PROBE [1]
#SELECT PROBE [NEG]
#SELECT PROBE [2, POS]
#SELECT PROBE [1, NEG]
