Fail-safe direct starters F-DS1e-x
The fail-safe direct starter with electronic overload protection can either power-up or power-
down the connected motor (implemented in the application through the PLC I/O interface).
Further, when the SG signal is missing at the upstream PM-D F, the PM module can
shutdown the motor in a safety-related fashion.
Depending on the type, three-phase motors up to 7.5 kW can be connected and operated
with integrated protection against overload and short-circuit.
On the one hand, the SG 1...SG 6 safe shutdown group will be assigned to the fail-safe
motor starter using the STEP 7 hardware configuration. On the other hand, the assignment
is realized using the coding connector on the terminal module of the motor starter. Both
assignments must match one another.

Significance and use of the individual signals:
No (external) wiring is require (except for the 24 VDC power supply). The safety-oriented
shutdown is performed internally using the SG 1...SG 6 shutdown groups. In addition to the
safety-oriented shutdown using the upstream PM-D F PROFIsafe module, if the shutdown
group has been enabled, the motor starter can be enabled and disabled using its PLC output
interface.
