Introduction to the manual
Contents of this chapter
This chapter describes the manual in short and gives some general information for the
reader. This chapter also contains a quick reference guide for implementing a safety system.
Applicability
The manual applies to ACS880-07/17/17LC/37/37LC drives which have the Q965:
Safely-limited speed with the encoder interface. For the Q965, ABB installs the
FSO-21 safety functions module (Q972) and the FSE-31 pulse encoder interface
module (L521) to the drive.
Required versions when using the FSO-21 module with Q965:
•
ACS880 primary control program: 2.2 or later
•
FSO-21 safety functions module: revision D or later
•
FSE-31 pulse encoder interface module: revision D or later
•
Drive composer pro: 1.8 or later.
The FSO-21 module safety functionality described in this manual is valid for revision H. For
earlier FSO module revisions, not all functionality related to the SLS function is supported.
Target audience
The manual is intended for people who install, start up, use and service the safety function.
Read the manual before working on the unit. You are expected to know the fundamentals
of electricity, wiring, electrical components, electrical schematic symbols, and functional
safety.
