6.5 Instructions on safe and EMC-compliant
installation
6.5.1 Explanations and terms
Electromagnetic compatibility (EMC) or electromagnetic interference (EMI) involves the
following requirements:
Interference
immunity Sufficient interference immunity of an electrical system or electrical
device against external electrical, magnetic or electromagnetic
noise via lines or space.
Interference
emission Sufficiently low interference emission of electrical, magnetic or
electromagnetic interference of an electrical system or an electrical
device on other devices in the environment via lines and space.
6.5.2 General information on EMC
Interference emission and resistance to interference of a stepping motor controller always
depend on the complete design of the drive, which consists of the following components:
Components - Power supply
- Stepper motor controllers
- Motor
- Electromechanical components
- Design and type of wiring
- Higher-order control system
In order to increase the interference immunity and decrease the interference emission, the
CMMS-ST already has integrated motor throttles and mains filters, which means that the
CMMS-ST stepping motor controller can be operated without additional screens and filters
in most applications.
The CMMS-ST stepping motor controllers were qualified in
accordance with product standard EN 61800-3 which applies to
electrical drives.
In the majority of cases, no external filter measures are required
(see below).
The conformity declaration to EMC directive 89/336/EEC is
available from the manufacturer.
6.5.3 EMC areas: second environment
When suitably installed, and with suitable cabling for all connections, the CMMS-ST
stepping motor controller conforms to the requirements of the corresponding EN 61800-3
product standard. This standard no longer refers to “limit value classes” but rather to so-
