Controlling safety functions STO and SLS via PROFIsafe with PROFINET for a

SINAMICS S120 drive line-up is demonstrated using this application example.

PROFIsafe telegram 901 can be used to control the safety function and also enter

a safety-relevant speed limit.

The drive line-up in the booksize format comprises an infeed and a Double Motor

Module (DMM). A CU320-2 Control Unit is used to control the motor. The extended

setpoint channel is used to enter a speed setpoint. The servomotor is controlled

using the Double Motor Module. A Smart Line Module (SLM) is used as infeed.

The safety-related signals are sensed using fail-safe inputs of the F-CPU and

evaluated in the F-CPU. The safety functions integrated in the drive are controlled

via the fail-safe PROFIsafe communication.

A variable SLS limit is entered depending on the states of the signals of the

protective door and the light barrier. The F-CPU evaluates the signals, and
