ACS880 FSO Safety Notice – Motor Phase Order Parameter

This safety notice addresses a potential safety risk in ACS880 drives equipped with FSO-11, FSO-12, or FSO-21 modules, where changing parameter 99.16 (Motor phase order) after safety validation can cause undetected reversal of motor rotation direction, bypassing asymmetrical speed monitoring limits. The document lists affected firmware versions, describes the specific conditions under which the issue occurs, and provides two corrective measures: locking the parameter via a delta loading package or updating the drive firmware.
