6.7 Control via PROFIsafe
Introduction
The safety functions of the drive can be controlled via terminals and the TM54F module as
well as the PROFIsafe message frame 30. Each drive with a configured PROFIsafe in the
drive unit represents a PROFIsafe slave (F-slave) with fail-safe communication to the F-host
via PROFIBUS.
A separate PROFIsafe message frame is created for each drive (PROFIsafe slot).
Control of the basic functions via the Control Unit and Motor Module (p9601.0/p9801.0)
terminals may be enabled in parallel. In this way, the STO, SBC, and SS1 functions
(time controlled) can be selected via PROFIsafe as well as via the on-board terminals on the
Control Unit and Motor Module.
