In the case of SS1 applications, the
quick stop function OFF 3
(undelayed contact block,
terminal X177.15 DI/DO 4) of
SINAMICS DCM
is guided via the safety relay.
Note
In the case of SS1 applications, the OFF 3 ramp of the SINAMICS DCM and the setting of
the delay time on the safety relay, must be manually set to the process and adjusted and
coordinated with one another when commissioning the system.
