3-2-5 Wiring for Conformity to EMC Directives
When the wiring conditions provided in this section are satisfied, the wiring will conform
to EMC Directives (EN55011 Class A Group 1 (EMI), EN61000-6-2 (EMS)). These
conditions were stipulated when EMC Directive approval was obtained for the W
Series. They will be affected by the installation and wiring conditions resulting from the
connected devices and wiring when the W Series is built into the system. Therefore,
the entire system must be checked for conformity.
The following conditions must be satisfied in order to conform to the EC Directives.
• The Servo Driver must be mounted in a metal case (control box). (It is not necessary to mount the
Servomotor in a metal box.)
• Noise filters and surge absorbers must be inserted in power supply lines.
• Shielded cable must be used for I/O signal cables and encoder cables. (Use tinned soft steel wire.)
• Cables leading out from the control box must be enclosed within metal ducts or conduits with
blades. (It is not necessary to enclose the 30-cm power cable, encoder cable, or connectors in a
metal duct or conduit.)
• Ferrite cores must be installed for cables with braided shields, and the shield must be directly
grounded to a ground plate.
