Warning
The following chapter describes the uses of the "Safety Integrated" functionality. The
detailed knowledge of the "Safety Integrated sl Function Module" (FBSI sl) is assumed as
prerequisite.
4.1 4.1 SINAMICS Safety Integrated
SINAMICS Safety Integrated provides the following safety functions:
● Safe standstill (SH)
● Safe Brake Control
1. The functions must be released using parameters.
2. The control terminals for the Safe Standstill (SH) function can be grouped.
3. The functions are drive-integrated, i.e. they are present for each drive and must be
individually brought into operation for each drive.
4.1.1 Control of the "Safe Standstill" Safety Function
Terminals for safe standstill
The safe standstill function is selected/deselected separately for each drive using a specific
terminal on the Control Unit and Motor Module.
● Control Unit
The required input terminal for safe standstill (SH) is selected via the BICO
interconnection (BI: p9620).
Digital input DI 0 ... DI 7 on the Control Unit can be used as a signal source (NCU). The
NX modules have DI 0 to DI 3 digital input.
● Motor Module
The input terminal for "safe standstill (SH)" is terminal "EP" ("enable pulses").
Both terminals must be simultaneously energized, otherwise a fault will be issued.
