  • Page 50: Feedback

    Servo motors can perform speed-dependent safety functions for safe speed and / or safe rela- tive position monitoring in a drive system by Lenze inverters or Controllers. In case of inver- ters, these functions are implemented by integrable safety modules and in case of Controllers by the additionally required Safety Controller.
