Set Read-In Disable (Rdisable) - Siemens Sinumerik 840D sl Programming Manual

10.4.3

Set read-in disable (RDISABLE)

Function
Using RDISABLE, when the condition is fulfilled, the additional block processing is held in the
main program. Programmed synchronized motion actions are still executed, the following
blocks are still prepared.
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, if the control is in the
continuous-path mode (G64, G641 ... G645).
Application
RDISABLE can be used, for instance, to start the program in the interpolation cycle as a
function of external inputs.
Example
Program code
WHENEVER $A_INA[2]<7000 DO RDISABLE
...
N10 G01 X10
N20 Y20
...
General conditions
Effect of RDISABLE for axis interchange
If RDISABLE acts on a block, in which also an axis interchange is executed, then RDISABLE
also acts on the REPOSA block initiated by the axis interchange.
Sample program:
Program code
N100 G0 G60 X300 Y300
N105 WHEN TRUE DO POS[X]=20 FA[X]=20000
N110 WHENEVER $AA_IM[X]<>20 DO RDISABLE
N115 G0 Y20
N120 Y-20
N125 M30

Comment
; Program processing is stopped if the
voltage at input 2 drops to below 7
V (assuming that the value 1000
corresponds to 1 V).
; RDISABLE acts at the end of N10,
when the condition is fulfilled
during its processing.
