Description Of Stop E - Siemens SINUMERIK 840D sl Function Manual

Comment regarding INCH-METRIC switchover:
The calculated value should be rounded off to one decimal place so that for an INCH-
METRIC switchover, internal rounding effects can be compensated and no undesirable
alarms are initiated.
● Alarm message for an internally initiated STOP D:
The alarm message "STOP D initiated" is output.
● Acknowledgment for an internally initiated STOP D:
An unintentional restart is prevented for STOP D. The error can be acknowledged using
the NC-RESET key.
SGA "STOP D is active"
This signal indicates that STOP D is active.
0 signal: STOP D is not active
1 signal: STOP D is active.
SGE deselect external STOP D
If a stop request is active, SGA "STOP D is active" is set in the same way as it would be for
an internally triggered STOP D.

external braking request, in this case "deselect external STOP D" (path braking).
An external STOP D can also be initiated in the drive monitoring channel from the PLC-SPL
CDC - or the PROFIsafe/FSEND-FRECV communication interface on the PLC side.
