the inverter unit STO function. The inverter unit STO function is active until the fault hasbeen repaired.The FSO module goes into Fail-safe mode. The STATUS/FAULT LED of the FSO moduleis red until the fault has been repaired.To exit the Fail-safe mode, remove the cause of the fault and reset the FSO module byswitching the power off and on, by pressing the Boot FSO button on the Safety view of Drivecomposer pro or with inverter unit parameter 96.09 FSO reboot.For more information, see the inverter unit firmware manual and the FSO module user’smanual.￭ STO function in the inverter unitsThe STO function in the inverter units has internal fault diagnostics and a fault reactionfunction which causes a fault trip in case it detects a redundancy fault of STO control signalsor any internal failure. See the hardware and firmware manuals of the inverter unit.Parameter settingsThis section lists the parameters that you have to set in the FSO modules and the inverterunits.The person who configures the safety functions in the FSO module must be a competentperson as required by IEC 61508-1 clause 6. In this context, the person must have expertiseand knowledge of functional safety, the safety functions as well as the configuration of theFSO module. We recommend our training courses on the FSO module.The parameter values given in this chapter are example values safety function(s) presentedin this manual. Actual parameter values of the delivery may vary. You must always checkthat the parameter settings match your application needs.￭ FSO module parameter settingsYou need the Drive composer pro PC tool to set the FSO module parameters, and apassword to be able to download the configuration to the FSO module from Drive composerpro. For the default password of the FSO module, see the FSO module user’s manual. Formore information on the Drive composer pro PC tool, see Start-up and maintenance PCtool Drive composer user’s manual (3AUA0000094606 [English]).Note: When the motor is running, you cannot change the password, adjust parametervalues, nor upload or download the FSO configuration file.Follow the configuration steps described in the FSO module user’s manual, chapterConfiguration.There are parameters that you must always set and parameters that are related to certainsafety functions only.
