Introduction
With increasing automation, protection of persons against hazardous movements is
becoming more important. Functional safety describes the measures needed by means of
electrical or electronic equipment to reduce or remove danger caused by failures.
During normal operation, safety equipment prevents people accessing hazardous areas. In
certain operating modes, e.g. set-up mode, work needs to be carried out in hazardous
areas. In these situations the machine operator must be protected by integrated drive and
control measures.
Drive-based safety provides the conditions in the controls and drives to optimise the safety
functions. Planning and installation expenditure is reduced. In comparison to the use of
standard safety engineering, drive-based safety increases machine functionality and
availability.
7.1.2
Drive-based safety with L-force | LCU
The motor starters of the ELCAMxIxxx4SNNPSNN series are equipped with ”drive-based
safety”, providing safety functions for the protection of persons working on machines.
The safety functions meet the requirements of EN 954, part 1, control category 3.
