SINAMICS S: Safety-control of a S120 using S7-300/400 (STEP 7 V5) with PROFINET and Safety Integrated (encoderless via PROFIsafe)

Task:

Control of Safety Integrated Extended Functions SS1, SLS and SDI using PROFIsafe with PROFINET for encoderless drives.

Solution:

This function example shows how safety functions SS1, SLS and SDI are controlled via PROFIsafe with PROFINET at a SINAMICS S120 drive.
The drive line-up in the booksize format comprises an infeed and a Double Motor Module. A Control Unit CU320-2 DP is used for the closed-loop motor control. An induction motor is controlled using the Double Motor Module without an encoder. The second connection (-X1) is not used in this example. A Smart Line Module is used as infeed.

The safety-relevant signals are sensed using fail-safe inputs of the ET200M and logically processed in the F-CPU. From the fail-safe data, the F-CPU generates a PROFIsafe telegram for the drive. This is transferred to the drive via PROFINET; there, it controls the safety functions.
