In order to increase the interference immunity and decrease the interference emission, the
CMMD-AS motor controller already has integrated motor chokes and mains filters, which
means that it can be operated without additional shielding and filters in most applications
(up to a max. motor line length of 15 m).
The CMMD-AS motor controllers have been approved in accordance
with the product standard EN 61800-3 applicable to electrical
drives.
In the majority of cases, no external filter measures are required
(Chapter 5.5.3).
The EMC guidelines Declaration of Conformity is available from the
manufacturer.
6.5.4 EMC areas: second environment
When suitably installed, and with suitable cabling for all connections, the CMMD-AS 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-called
"environments". The "first" environment includes electricity grids connected to
residential housing. The "second" environment includes grids connected only to
industrial plants.
For the CMMD-AS motor controller without external filtering measures, the following
applies:
EMC class Range Compliance with EMC requirements
Interference
emission Second environment (industrial) Motor cable length up to 15 m
Interference
immunity Second environment (industrial) Regardless of motor cable length

6.5.5 EMC-compliant wiring
The following must be observed for EMC-compliant installation of the drive system (see

Warning
All PE cables must be connected before commissioning for reasons
of safety.
The protective earth regulations in EN 50178 and EN 60204-1 must
always be observed in the installation!
1. To keep leaked current and losses in the motor connection cable as low as possible,
the motor controller CMMD-AS should be placed as close to the motor as possible.
2. The motor and angle encoder cables must be screened.
3. The screening of the motor cable is fitted to the housing of the CMMD-AS servo
positioning controller (screened connection terminals). The cable screen is also always
fitted to the corresponding motor controller to prevent leaked current flowing back to
the controller which caused it.
