Meaning.
The CNC activates this mark if the gap is within the range defined by the
parameters GAPMIN-GAPMAX.

GAPMIN-GAPMAX, the CNC disables the INPOSGAP mark and stops
the movement of the axes. The CNC will display an error or not,
depending on how the parameter GAPERRORCANCEL has been set.
In the event of an error, the CNC stops the movement of the axes,
according to the braking ramp and controlling the gap during the ramp.
The CNC activates this mark if the gap is within the tolerance limit defined
by the parameter GAPTOL regarding the gap value programmed.
If the axis exceeds the tolerance set in the GAPTOL parameter, the CNC
deactivates the INTOL mark. The CNC will display an error or not,
depending on how the parameter GAPTOLCANCEL has been set. In the
event of an error, the CNC stops the movement of the axes, according
to the braking ramp and controlling the gap during the ramp.
Meaning.
If the PLC sets this mark at a high logic level, the CNC channel
momentarily interrupts the movement of the axes. When the mark
returns to the high logic level, the movement of the axes continues. All
the stops and starts of the axes are carried out with the corresponding
acceleration and deceleration.
• This mark does not affect the independent movement of an axis
(independent interpolator).
• On hirth axes, if the axis does not stop in a particular position, the
CNC does not activate the MATCH(axis) mark.
• This mark does not turn off the laser. If the power control is active,
the laser removes the minimum defined power.
If the PLC sets the _FEEDHOL at a low logic level in a motionless block,
the CNC continues executing the program until it detects a motion block.
The "Freal" text of the screens of the automatic and jog modes shows
the status of this mark. The text appears in red when the _FEEDHOL
mark is active. The status of the mark is not displayed if the screen does
not show this text.
If the PLC sets this mark at a low logic level, the CNC channel interrupts
the execution of the part program. To resume the execution of the
program, besides setting this mark at a high logical level, the PLC should
activate the CYSTART mark.
• This mark does not affect the independent movement of an axis
(independent interpolator), which also does not affect the key
[STOP].
• This mark does not turn off the laser.
• This mark does not disable gap control, except in approach
movement. In this case, the axis will remain stationary and without
gap control until the movement is resumed.
The treatment received by the signal _STOP is similar to that given to
the [STOP] key in the CNC. With this signal at a low logic level, all keys
remain enabled.
This mark is active by default. The PLC deactivates this mark to disable
the active gap control. The PLC activates this mark to enable the active
gap control in the CNC; if no gap control is active, this mark does nothing.
The PLC activates this mark to indicate that the collision sensor has been
activated. This mark is not kept in memory. When this mark is active, the
CNC will display an error or not, depending on how the parameter
GAPCOLLISIONMODE has been set.
