2.3 Using the Advanced Safety Option Board
The Advanced safety option board is used to implement safety functions in accordance with the standard EN IEC 61800-5-2. The
option board handles the safe I/O and the monitoring of active safety functions. The option board does not handle the control of
the AC drive. The AC drive can be controlled, for example, with the drive application, or the external process control system can give
the speed reference to the AC drive.
The Advanced safety option board must be used with a subsystem that provides the STO function, it is not possible to use the
Advanced safety option board alone. The STO function is provided, for example, by the OPTAF STO option board. To use the safety
functions that do speed monitoring, an external speed sensor is necessary. The sensor can be a digital or an analog encoder or a
digital proximity sensor.
When using a safe fieldbus, install an option board that supports the fieldbus.
The
closed-loop control are optional. The possible configuration and available features can depend on other option boards and their
installation slots.
