Library Safe Drive Functions

… Design Packages for a significantly faster time-to-market!

The complexity associated with the development of industrial drives based on the latest safety standards is high. In particular, if advanced safety functions (i.e. more than just STO – safe torque off) are required, development time and effort usually increase significantly.

With the Software Library Safe Drive Functions you get self-contained, tested and ready-to-use software modules. The product development gets easier, faster and the risk is much lower.

«MESCO Design Packages: A product of MESCO Systems.»

Typical Applications

  • Frequency converters
  • Servomotors
  • Linear drives


The library for safety drives contains 11 safety functions according the relevant product standard IEC 61800-5-2. All functions can be easily embedded directly in the safety drive or on an optional safety option board.

The development of our library follows all relevant safety standards. It can be integrated directly in your project thus helping you achieve significant savings in development time. As an added benefit to you the product certification will be made much easier. This reduces development risks and use of valuable development resources. 

We support you with the integration of the library and help you with product development.
