Control System Behavior Category
The following paragraphs relate to the requirements of European (EU/EEA) directives for
Machinery, Electric Safety, and Electromagnetic Compatibility (EMC).
In situations with low exposure consideration factors, European Standard EN 1050
specifies use of a Category 1 Control System per EN 954. EN 954 defines a Category 1
Control System as one that employs Category B components designed to withstand
environmental influences, such as voltage, current, temperature, EMI, and well-tried
safety principles. The standard control system described in this manual employs
hardware components in its safety system that meet or exceed the requirements of the EU
Machinery Directive and Low Voltage Directive.
The standard control system is fully-hardened to all EMI influences per the EU EMC
Directive and meets all functional requirements of ISO 10218 (EN 775) Manipulating Robots
Safety. In addition, a software-based reduced speed mode has been incorporated to limit
speed and impact forces on the Operator and production tooling when the robot is
operated in Manual Mode.
The standard control system meets or exceeds the requirements imposed by the EN 954
specified Category 1 level of safety.
