9. en turning off the motor is essential to safety related functions in the system the F7 s flexibility necessitates a reliable mechanism to ensure that the motor will stop and cannot be started regardless of how the drive is programmed configured or controlled otherwise The Safe Off option when used with other safety components provides protection according to EN954 1 Category 3 for safe stop and protection against restart An F7 drive equipped with the Safe Off option is just one component in a safety control system To assure that the Safe Off function appropriately fulfills the safety requirements of the application a thorough risk assessment shall be done according to ISO12100 for the whole safety system at the final installation All components in the system must be appropriately selected and applied to achieve the desired safeguarding The Safe Off function performs a safe stop according to the EN60204 1 Stop Category 0 referred to as uncontrolled stop by power removal or coast to stop Safe Off is certified to meet the requirements of the EN954 1 Safety Category 3 The Safe Off function is implemented totally in hardware on the F7 control board Safe Off disables the motor not the drive controller Power to the control board and display is maintained so all parameters monitors and fault data may be read and observed Also all communications Modbus Profibus DeviceNet EtherNet IP etc stay active The Safe Off function us
