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.

The alarm message "STOP D initiated" is output.
S Acknowledgment for an internally initiated STOP D:
An unintentional restart is prevented for STOP D. The error can be acknowl-
edged using the NC--RESET key.

If a stop request is active, SGA "STOP D is active" is set in the same way as it

selection of the external braking request, in this case "deselect external STOP D"

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.
