2.4 EMC Installation Conditions
This section describes the recommended installation conditions that satisfy EMC
guidelines when combining a SGDV SERVOPACK in the DC power input Σ-V series
with a SGM7M servomotor in the Σ-7mini series or a SGMMV servomotor in the Σ-
Vmini series.
The recommended installation conditions for SERVOPACKs with
MECHATROLINK-III communications are described here. For SERVOPACKs with
a different interface, refer to the following installation conditions.
The following illustration shows the EMC installation conditions satisfied in test con-
ditions prepared by Yaskawa. The actual EMC level may differ depending on the
actual system’s configuration, wiring, and other conditions. However, because this
product is built-in, check that the following conditions are still met after being
installed in the user’s product.
The applicable standards are EN55011 group 1 class A, EN 61000-6-2, EN 61000-6-
4, and EN 61800-3 (Category C2, Second environment).
