Product overview
4.1.1
Purpose
As processes become increasingly automated, protecting people from potentially hazardous
movements is gaining in importance. Functional safety describes the measures offered by
electrical or electronic devices that are required to reduce or eliminate malfunction-induced
hazards. In normal operation, safety devices prevent human intervention in hazardous areas.
In certain operating modes, during set-up for example, people also need to be in hazardous
areas. In such situations, the machine operator must be protected by drive and internal
control measures.
Integrated functional safety technology provides the conditions required by controller and
drive for the optimised realisation of safety functions. Planning and installation complexity is
reduced. The use of integrated functional safety technology increases machine functionality
and availability over the levels achieved by conventional safety technology.

Supported devices
The SE-Power FS Safety Module STO can only be used in servo drives in conformity with
Section 3.1.2
As a standard, the SE-Power FS series servo drives come supplied with the ordered safety
module (STO or MOV) for integrated functional safety.
The use of the SE-Power FS Safety Module STO enables the safety functions, described in
this product manual for the integrated functional safety of safety stops, to be expanded.
For the use of the SE-Power FS Safety Module MOV it requires the manual
