Product Innovation

Integrated safety technology for electric drives

This project involved the development of an integrated safety module for the control of electric motors. Zühlke created the software components for monitoring the drive.

Customer benefits

  • Iterative and risk-based approach renders project progress measurable.
  • Analysis of system-wide requirements with use cases provided clear specifications for all sub-projects.
  • Punctual delivery of TÜV-certified safety module.

Task

The European Machinery Directive requires manufacturers to guarantee a machine that can be operated, equipped and maintained without endangering human beings if used as intended. Previous solutions required a separate safety equipment alongside the control equipment to ensure reliable protection from uncontrolled movements. 

Solution

With its new integrated safety equipment, the new Servo Drive 9400 system from Lenze offers considerable advantages in terms of costs and benefits (drivebased safety). Together with the customer, Zühlke developed replaceable safety modules for this purpose featuring gradu-al, flexible functionality.
