Open the STO Request contacts
simultaneously. The contacts must
remain open for the entire duration
that STO is required, they must not
be momentary action switches. The
drive will confirm via X11/05 that STO
has been invoked by the lamp being
ON.
If the lamp is OFF, do not access the
machine as a fault may be present.
Note: if the STO Request contacts
open while the motor is rotating, the
motor will coast to rest
(unless external forces act on it).
