This mark always affects the movements of the independent axis programmed from the
CNC; the ones programmed from the PLC depend on parameter XFITOIND. If the PLC
deactivates the _XFERINH mark, the CNC channel interrupts the movements of the
independent axis when they reach position and inhibits the execution of the next movement.
To manage the transfer inhibit in an independent movement, the PLC also has a particular
mark per axis (_IXFERINH(axis) mark). See
" _IXFERINH(axis)" on page 439.
_FEEDHOL
There is a mark for each channel. The mnemonics for each channel are the following.
_FEEDHOLC1 (can also be programmed as _FEEDHOL)
_FEEDHOLC2 _FEEDHOLC3 _FEEDHOLC4
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 stop the spindle.
• 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.
CYSTART
There is a mark for each channel. The mnemonics for each channel are the following.
CYSTARTC1 (can also be programmed as CYSTART)
CYSTARTC2 CYSTARTC3 CYSTARTC4
When the operator presses the [START] key, the CNC lets the PLC know by activating the
START mark. If the rest of the conditions are met (hydraulic, safety, etc.), the PLC must
activate the CYSTART mark in order for the program to start running.
SBLOCK
There is a mark for each channel. The mnemonics for each channel are the following.
SBLOCKC1 (can also be programmed as SBLOCK)
SBLOCKC2 SBLOCKC3 SBLOCKC4
If the PLC sets this mark high (=1), the CNC switches to SINGLE BLOCK operation mode.
XFITOIND Meaning.
Yes The _XFERINH mark affects the movement of the independent axis programmed
from the PLC and from the CNC.
No The _XFERINH mark does not affect the movements of the independent axis
programmed from the PLC; but it does affect the ones programmed from the
CNC.
START AND (rest of conditions) = CYSTART
