Electromagnetic compatibility (EMC) is the ability of an electrical device
to function, fault-free in a specified electromagnetic environment without
influencing the environment in an inadmissible fashion.
This design- and EMC guideline supplements the documentation on the
individual components.
The SIMADYN D control system consists of individual components (e. g.
subracks, modules, interface modules, operator control panels, position
transmitters). The components can be installed in the widest range of
system configurations according to individual requirements. When the
components are arranged in a distributed fashion (decentral topology) a
noisy environment cannot be neglected. Thus, specific requirements are
placed on the design and EMC of the system.
EMC represents a quality feature for
• Intrinsic noise immunity: Immunity against internal electrical noise
and disturbances
• External noise immunity: Immunity against external electromagnetic
noise
• Noise emission level: Influencing the environment due to
electromagnetic radiation
In order to achieve the highest possible operational reliability and safety
and noise immunity for a complete system (closed-loop control and drive
motor) the control manufacturer and user (including end customers) must
take certain measures.
Perfect functioning of SIMADYN D can only be guaranteed and the legal
requirements fulfilled (89/336/EC) if all of these measures are observed.
SIMADYN D components are designed for use in industrial environments
in accordance with EN 50081-2 and
EN 50082-2. They may not be operated or connected to the public low-
voltage network.
