Overview
The safety functions module kit provides the FSO-12 module along with power cable, STO cable, data cable, control board mounting plates, connector plugs and mounting screws, along with a user’s manual. The FSO-12 safety functions module supports the following functions according to EN/IEC 61800-5-2:2007: Safe Torque Off (STO) standard feature Safe brake control (SBC) Safe stop 1 (SS1) Safely-limited speed (SLS) Additional safety functions supported but not specified in EN/IEC 61800-5-2:2007: Safe stop emergency (SSE) Safe maximum speed (SMS) Prevention of unexpected start-up (POUS) The FSO-12 does not operate the drive; it only monitors the actions of the drive and commands safety functions to be executed. The request for safety functions can come from an external safety system, safety PLC or from an FSO-12 internal fault. The FSO module monitors that the drive operates within the configured limits, and if the limits are exceeded, activates the STO function in the drive within the response time. Activation of the drive STO function removes the torque and, if so configured, applies the brake. Commissioning and configuration of the safety functions requires Drive composer pro (DCPT-01-KIT). NOTE: The Safe Torque Off (STO) function does not disconnect the voltage of the main and auxiliary circuits from the drive. NOTE: The FSO-12 module does not support an encoder in safety applications.
