  • Page 8: Safety Functions

    Integrated Safety Technology Safety functions Safety functions The following drive-related safety functions can be used: • STO (safe torque off according to IEC 61800-5-2) by disconnecting the STO input. If the STO function is activated, the frequency inverter no longer supplies power to the motor for generating torque.
  • Page 9 Integrated Safety Technology Safety functions • SS1(c) (safe stop 1, function variant c according to IEC 61800-5-2) by means of suit- able external control (e.g. safety relay with delayed disconnection) The following sequence is mandatory: – Decelerate the drive using an appropriate brake ramp specified via setpoints. –...

  • Page 10: Restrictions

    Integrated Safety Technology Restrictions Restrictions WARNING The safety concept is only suitable for performing mechanical work on the system/ma- chine components. If the STO signal is disconnected, the supply system voltage is still present at the ® MOVIGEAR DC link. Severe or fatal injuries from electric shock.

  • Page 11: Safety Conditions

    Safety Conditions Approved units Safety Conditions ® The requirement for safe operation is that the safety functions of MOVIGEAR are prop- erly integrated into an application-specific higher-level safety function. A system/ma- chine-specific risk assessment must be carried out through the system/machine manu- ®...

  • Page 14: External Safety Controller Requirements

    Safety Conditions External safety controller requirements External safety controller requirements A safety relay can be used as an alternative to a safety controller. The following require- ments apply analogously. • The safety controller and all other safety-related subsystems must be approved and tested for at least that safety class which is required in the overall system for the re- spective, application-related safety function.
  • Page 15 Safety Conditions External safety controller requirements ® • Note the following for two-pole disconnection of MOVIGEAR with tested, safe out- puts: – When disconnected, the switch-on test pulses may never occur at the plus and minus output at the same time. –...

  • Page 16: Startup Requirements

    Safety Conditions Startup requirements Startup requirements • To validate the implemented safety functions, they must be documented and checked after successful startup (validation). Observe the limitations for safety functions in chapter "Limitations" for the validation of the safety functions. Non-safety-relevant parts and components that affect the re- sult of the validation test must be deactivated, if necessary.
