1.5 Safe probing cycles.
The probe is protected against collisions in positioning and withdrawal movements, inside
the probing cycles and in any movement where G100 has not been programmed. The CNC
supports monitoring with RTCP and inclined planes.
Collision management is not compatible with non-stop probing processes (G104).
Movements that use this type of probing must disable the safe mode of the probe
(PROBE1MONIT=0 or PROBE2MONIT=0).
Loop level monitoring, controlling all the collision scenarios in any of the two probes. The
CNC can monitor the probes connected to the local inputs and to the remote CAN inputs.
The CNC monitors the two probe inputs at the same time.
For moves in automatic mode, if the CNC detects a collision in a positioning or withdrawal
movement inside a probing cycle, or even outside of it, it stops the movement, displays the
corresponding error message, opens the emergency relay and activates the _ALARM (level
"0") signal, When a collision occurs while the axes are not moving, the CNC does not display
an error. The CNC will only allow jogging the probe away.
For manual (jog) movements, if the CNC detects a collision, it stops the probing movement
and displays the corresponding error. The CNC will only allow moving the probe away.
PLC marks.
The following PLC marks allow enabling or disabling collision monitoring for a probe in safe
mode.
PROBE1ENA
PROBE2ENA
These are active marks by default. These mark indicate that the probe has is enabled. When
executing a G100 or G103 command, the CNC will issue an error message if the mark of
the active probe (the one selected with #SELECT PROBE) is not enabled. These marks do
not limit the monitoring of the safe mode.
These marks should be tested in the subroutines Sub_Probe_Tool_Begin.fst and
Sub_Probe_Piece_Begin.fst so the subroutine waits until the mark is active.
PROBE1MONIT
PROBE2MONIT
These marks are associated with the safe mode of the probe. If the mark is active, the probe
is in safe mode monitoring collisions.
These marks should be tested in the subroutines Sub_Probe_Tool_Begin.fst and
Sub_Probe_Piece_Begin.fst to warn, if they are deactivated, that the probe is in non-safe
mode.
