Frequency converters with integrated safety functions

For applications with variable speed

Frequency converters are used to operate motors with variable speed. Typical areas of application are standard applications in which the operation of the motors with variable speed is desired: pumps, fans, compressors, conveyor applications; but frequency converters are also used in the operation of extruders and hoists. Siemens offers a comprehensive range of frequency converters in various forms for different key applications. They not only have the basic integrated safety features such as Safe Torque Off, but are also characterized by high-quality integrated safety functions.
