Page 4: Basics
The STO function can be used also to prevent unexpected start up of the motor. The STO function in the Sinus Penta, Penta Marine and Iris Blue drives is obtained at a hardware level and its activation is absolutely independent of the software and the CPU of the inverter. The drive firmware implements only non-critical diagnostic functions related to the STO function. -

Page 8: Scope And Application
STO FUNCTION SINUS PENTA APPLICATION MANUAL PENTA MARINE IRIS BLUE 1.2. Scope and Application The drives support the Safe Torque Off (STO) function according to standards EN 61800-5-2:2007, EN ISO 13849-1:2008, EN 61508:2010. The STO may be used where power cut off is required to prevent unexpected start up. The STO function disables the control voltage of the power semiconductors of the drive output stage, thus preventing the inverter from generating the voltage required to rotate the motor (see diagram below). -

Page 16: Diagnostics
STO FUNCTION SINUS PENTA APPLICATION MANUAL PENTA MARINE IRIS BLUE 4. DIAGNOSTICS The STO function is based on a double channel with diagnostic (1oo2 in the IEC 61508-6 nomenclature) hardware architecture. This means that diagnostic tests are required to validate the STO function and to periodically verify the hardware integrity. - Page 17 STO FUNCTION SINUS PENTA APPLICATION MANUAL PENTA MARINE IRIS BLUE The DT01 proof-test needs to be performed in 4 steps: Step nr1 Drive is working with motor torque applied to motor. This condition is obtained by energizing both STO input signals (ENABLE-A and ENABLE-B) and transmission of PWM commands from Microcontroller to the IGBT Drivers.
