    Integrated safety technology Safety functions Safety functions The following drive-related safety functions can be used: 2.3.1 • STO (safe torque off according to EN 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 10 Integrated safety technology Safety functions 2.3.2 SS1(c) • SS1(c) (safe stop 1, function variant c according to IEC  61800-5-2) by means of suitable 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 11: Limitations

    Integrated safety technology Limitations Limitations WARNING The safety concept is only suitable for performing mechanical work on driven sys- tem/machine components. When the STO signal is disconnected, the line voltage is still present at the DC link ® of the MOVIGEAR drive unit.

  • Page 12: Safety Conditions

    Safety conditions Safety conditions ® The requirement for safe operation is that the safety functions of MOVIGEAR properly integrated into an application-specific higher-level safety function. A system/ machine-specific risk assessment must be carried out through the system/machine manufacturer and taken into account for the use of the drive system with ®...
