Switch off protection zone G60
resets protection zone monitoring. G60 is
programmed before the traversing command that is
to be monitored or not monitored.
Parameters
Q:
■ No input: Deactivate protective zone
monitoring for this block
■ Q=0: Activate protective zone (modal)
■ Q=1: Deactivate protective zone (modal)
Period of dwell G4
The CNC PILOT interrupts the program run for the programmed length
of time before executing the next program block. If G4 is programmed
together with a path of traverse in the same block, the dwell time only
becomes effective after the path of traverse has been executed.
Parameters
F:
Period of dwell
Range: 0 sec < F < 99.999 sec
Precision stop ON G7
G7 switches the ”precision stop” on modally. With a precision stop the
CNC PILOT does not run the following block until the last point has
been reached in the tolerance window for position (tolerance window:
machine parameter 1106, ff ”position control for linear axis”).
A precision stop affects single contours and cycles. The NC block
containing G7 is also executed with a precision stop.
Precision stop OFF G8
G8 switches the precision stop off. The block containing G8 is executed
without a precision stop.
Block precision stop G9
G9 activates a precision stop for the NC block in which it is
programmed (see also ”G7”).
