6.4.3 Installation Conditions of EMC Directives
To adapt a combination of a SGMH servomotor and a SGDM SERVOPACK to EMC Directives (EN55011
group 1 class A and EN61000-6-2), the following conditions must be satisfied.
(1) EMC Installation Conditions
This section describes the installation conditions that satisfy EMC guidelines for each model of the SGDM
SERVOPACK. The conditions required for the standard type (base mounted) of SERVOPACK are described.
Refer to this section for other SERVOPACK models such as the rack mounted types as well.
This section describes the EMC installation conditions satisfied in test conditions prepared by Yaskawa. The
actual EMC level may differ depending on the actual system’s configuration, wiring, and other conditions.
