RDISABLE

Programmed read-in disable RDISABLE
The RDISABLE command in the active section causes block processing to be stopped when
the relevant condition is fulfilled. Processing of programmed motion-synchronous actions still
continues. The read-in disable is canceled again as soon as the condition for the RDISABLE
is no longer fulfilled.
An exact stop is initiated at the end of the block containing RDISABLE irrespective of
whether or not the read-in disable is still active.
The exact stop is also triggered, when there is control of the continuous-path mode (G64,
G641, G642, G643, G644). RDISABLE can be programmed with reference to the block or
also modal (ID=, IDS=)!
Application: This method can be used, for instance, to start the program in the interpolation
cycle as a function of external inputs.
Example RDISABLE

N20 Y20
Program processing is halted if the voltage at input 2 drops to below 7 V (assuming that the
value 1000 corresponds to 1 V).
Application of this solution, for instance, read-in disable till the obstacle is removed.
2.4.10

STOPREOF

End of preprocessing stop with STOPREOF
A motion-synchronous action containing an STOPREOF command cancels the existing
preprocessing stop if the condition is fulfilled.
STOPREOF must always be programmed with keyword `WHEN' and as a non-modal
command.
Application: Fast program branching at the end of a block.
66
; RDISABLE acts at the end of N10, when
the condition is fulfilled during its
processing.
