In the following diagram the operation principles of both safety functions are shown.
Wiring and operating principles of the Safety Integrated Basic Functions Safe Torque Off and Safe Stop 1
On the various types of SINAMICS components the inputs of the safety functions have different terminal markings.
These are shown in the following table:
