4.2 Instructions for safe and EMC-compliant installation
The CMMS-AS -...-G2 motor controllers have been approved in accordance with product
standard E N 61800-3 that is applicable to electric drives. Components from Festo have
been used for this purpose (e.g. motor/encoder cables).
The declaration of conformity for the EMC directive (electromagnetic compatibility) is
available at www.festo.com.
4.2.1 Interference emission and interference immunity
In order to increase the resistance to interference and decrease the emitted interference, the
CMMS-AS -...-G2 motor controller already has integrated motor c hokes and mains filters, which means
that the motor controller can be operated without additional shielding and filters in most applications.
If installed correctly and if all connecting cables are wired correctly ( Chapter 4.2.2), the motor con-
troller fulfils product standard E N 61800-3 for the following range of application:
Permissible range of application
Emitted interference Second environment ( industrial)
1)
Resistance to interference Second environment ( industrial)
1)
1) Locations outside of the residential area, or industrial areas that are supplied from the medium-voltage power supply network
through their own transformer.
Tab. 4.1 Permissible range of application in accordance with E N 61800-3
Note
The built-in filter can be thermally overloaded if an application involves long motor
cables (15 … 25 m) or motor cables with an impermissible high cable capacity:
• Use additional filters for c ables 15 … 25 m long (see Tab. 4.2).
• Only use cables with a capacitance per unit length of < 200 … 150 pF/m between the
motor phase and screening; contact the cable supplier if necessary.
