Functionality depends on the parameterized Safety Integrated functions.
The functionality of the digital inputs DI 16 to DI 21 depends on the parameterized Safety
Integrated functions.

Relevant digital inputs
Control takes place via 2 switch-off signal paths:
1. switch-off signal
path
via D410-2 terminals
DI 0...3, DI 16 (X121.1...4 and X120.3)
The desired input terminal is selected via BICO
interconnection (BI: p9620[0]).

Extended functions Control takes place via the 2-channel F-DI of the SIMOTION D410-2: F-DI 0 ...
F-DI 2 (X120.3...11)
A fail-safe digital input is made up of 2 digital inputs.
If SIMOTION D410-2 is mounted separately (PM340 connected to SIMOTION
D410-2 via CUA31/32), use of the Safety Integrated Extended Functions via
the on-board terminals (F-DI, F-DO) is not possible.
The X120 interface has a connection for the motor temperature sensor.
You can use the temperature sensor connection to connect the temperature sensing via
KTY84-1C130 (special temperature sensor) or PTC (positive temperature coefficient). The
temperature sensing provides thermal motor protection by detecting critical motor conditions.
For more information on "thermal motor protection", see the
SINAMICS S120
Commissioning Manual.
NOTICE
The KTY temperature sensor must be connected with the correct polarity. A sensor
connected with the incorrect polarity cannot detect the motor overheating. For more
information on the temperature sensors and how to use them, refer to the
SINAMICS S120
Commissioning Manual, chapter entitled Temperature sensors for SINAMICS components.
