    Safety Function STO Characteristic data for „Safe torque off“ • Power supply for the rotation direction of the motor is interrupted (free-wheeling motor) • Used when monitoring of standstill is not necessary • Unintentional starting of the motor is prevented • No galvanic isolation of the motor from the inverter DC link What is realized by the STO function related to EN 60204 ? Emergency stop can be realized by the STO function, since the mains voltage may remain effective.

  • Page 22: Classification Of Sto According Iec 61508

    Safety Function STO This behaviour can occur either by a short circuit of the IGBTs or by interconnection (also short circuit) of the control drivers. The error should be regarded as critical, if the drive re- mains in STO status. Classification of STO according IEC 61508 2.6 • 10 2.3 • 10 on demand Proof-Test-Interval T 20 years For SIL classification in connection with the applications consider the failure rates of the ex- ternal switch devices for final evaluation. Classification of STO according EN ISO 13849 Category MTTF >1000 years high For the classification within a performance level in connection with the applications consider the failure rates of the external switch devices for final evaluation. Additional instructions • The unit must be isolated from mains by main switch when working on parts under volt- age.

  • Page 23: Functional Description

    Safety Function STO Functional Description The COMBIVERT with integrated safety function meets the following function according to IEC 61800-5-2: • „Safe torque off“ (Safe Torque Off – STO) The safety-related disconnection according to STO is reached by a two-cannel opto-coupler blockage. The supply of the opto-couplers, which are responsible for the commutation of the connected drive occurs via transformation coupling of the input voltage. This ensures at input voltage loss that no supply of the opto-couplers is possible. If the opto-couplers are not longer supplied, no IGBT can be controlled and thus no energy can be supplied to the drive.

The stop mode is not directly requested, but the maximum time until reaching the standstill is estimated. This period is loaded in a safe time relay, which dis- connects the drive finally from supply.
