FSO-12 and FSO-21 Safety function modules

Optional safety functions module (FSO-12 and FSO-21) provides an easy way to extend safety functions in ACS880 series drives.

Key benefits

As the level of automation in factories continues to grow, so does the importance of machine safety in industrial applications involving drives and motors. When safety is designed properly, it brings sound economic advantages, such as increased productivity and minimum downtime without generating additional risks.

Compact and reliable module

The plug-in module is installed and cabled inside the drive, enabling different safety functions and diagnostics in one compact and reliable module.

FSO-12

An encoderless variant of the safety functions module (FSO-12) with six safety functions in it.

FSO-21

A safety functions module (FSO-21) offers eight safety functions enabling the use of encoder feedback (FSE-31). The FSO-21 includes the same safety functions as the FSO-12, but offers two additional safety functions for your drive.

PROFIsafe

You can enable PROFIsafe over PROFINET connectivity, between your ACS880 drive and the safety PLC by adding the FENA-21 fieldbus adapter module to your drive. This way you will have a more flexible safety solution with the possibility to add safely-limited speed (SLS) to your application while it is in use.

SIL 3/PL capability and TÜV Nord certified

FSO-12 and FSO-21 safety functions modules have SIL 3/PL e capability and conforms to European Union Machinery Directive 2006/42/EC.

Drive composer

Selection and configuration of the safety functions is done using the Drive composer pro PC tool.

Functions included in FSO-12 and FSO-21

Safe stop 1 (SS1), Safe stop emergency (SSE), Safe brake control (SBC), Safely-limited speed (SLS), Safe maximum speed (SMS), Prevention of unexpected startup (POUS)

Additional functions in FSO-12

Prevention of unexpected start-up

Additional functions in FSO-21

Safe direction (SDI), requires the pulse encoder interface module FSE-31, Safe speed monitor (SSM)
