Understanding the Stop and EN954-Safety Categories / Generating an Emergency Stop

Industrial machinery has several operating and safety standards that it must meet for avoidance of hazardous conditions and for protection of personnel. Lenze-AC Tech frequency inverters are often installed in this type of machinery and from a safety point of view, the control functions of our drives should comply with these standards.
 
Industrial equipment often needs to follow both the NFPA 79 (Electrical standard for Industrial Machinery) and EN 60204 (Safety of Machinery & Electrical Equipment). There are two Category types when dealing with machine safety and the means to generate an emergency stop condition: Stop and Safety.
 
Stop Category: The NFPA 79 and EN 60204 standards use Stop Category 0, 1, and 2.
