SINAMICS Safety Integrated

STO (Safe Torque Off) safely removes the torque from a drive, but does not actively brake it. When a drive needs to be brought to a controlled standstill, SS1 (Safe Stop 1) can be used to safely monitor the electrical braking process.

In this video, we explain how SS1 works, which variants are available, and how brake monitoring can be used to safely stop a drive.

Safe communication between an F-PLC and a drive is essential for controlling drive-based safety functions. PROFIsafe provides the failsafe communication required to transfer safety-related signals between the F-PLC and the drive. In this video, we show how to easily set up PROFIsafe communication between an F-PLC and a drive. The library used in the example is available for free download.

A safety acceptance test verifies that the safety functions of a machine or drive have been correctly implemented and work as intended. It is an essential part of validating the safety of a machine and documenting that the safety requirements have been met. With SINAMICS Startdrive, you can easily perform and document the acceptance test for drive safety functions.

Take a closer look at the acceptance test:

• Video | Acceptance test on an example machine
  This video shows step by step how to perform an acceptance test on a real machine. As a result, the guided acceptance test delivers an automatically generated acceptance report - an important part of the machine documentation.
• Video | Partial acceptance after component replacement
  This video shows what to do after replacing a component on the machine. Which drive components are safety-relevant? Does the entire acceptance have to be run through again? How do I document the acceptance after a component exchange?

The Safety Activation Test is a tool in SINAMICS Startdrive that supports the safety acceptance test by guiding you through the verification of the configured safety functions. It helps ensure that the safety functions have been activated correctly and provides support during the acceptance process.
