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 air-cooled and liquid-cooled multidrives which have the
option: Prevention of unexpected start-up with STO, with FSO (option +Q950).
For the option +Q950, ABB installs the FSO-12 safety functions module (option +Q973) or
the FSO-21 safety functions module (option +Q972) to the inverter units. When safety pulse
encoders are used, ABB installs the FSE-31 pulse encoder interface module (option +L521)
and the FSO-21 module to the inverter units. Only the FSO-21 module supports the FSE-31
module and the use of safety pulse encoders.
Note: If you are using a safety pulse encoder/FSE-31 pulse encoder inferface module, refer
to FSE-31 pulse encoder interface module user's manual (3AXD50000016597 [English])
for more information.

•
ACS880 primary control program: 1.80 or later
•
FSO-12 safety functions module: revision C or later
•
