1.1 Basics
1.1.1 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.
1.1.2 Drive−based safety with L−force | 9400
The controllers of the L−force|9400 range can be equipped with a safety module. The
functional range of the safety module types varies in order to optimally implement
different applications.
"Drive−based safety" stands for applied safety functions, which can be used for the
protection of persons working on machines.
The motion functions are continued to be executed by the controller. The safety modules
monitor the safe compliance with the limit values and provide the safe inputs and outputs.
When the limit values are exceeded the safety modules start the control functions
according to EN 60204−1 directly in the controller.
The safety functions are suitable for applications according to IEC 61508 to SIL 3 and meet,
depending on the module, the requirements of Performance Level e (PL e) and control
category 4 according to EN ISO 13849−1.
