G5-series Linear Motors/Servo Drives With Built-in EtherCAT Communications
4-3
Wiring Conforming to EMC Directives
G5-series Servo Drives conform to the EMC Directives (EN 55011 Class A Group 1 (EMI) and EN
61000-6-2 (EMS)).
EMC-related performance of these products, however, will be influenced by the configuration, wiring,
and other conditions of the equipment in which the products are installed. The EMC conformance of the
system as a whole must be confirmed by the customer.
The certification of the Servo Drives is conducted with a representative rotary motor of each model by
an external certification authority.
The following five conditions are for conformance of G5-series products to the EMC directives.
•
The Servo Drive must be installed in a metal case (control panel).
•
Noise filters and lightening surge absorptive elements (surge absorbers) must be installed on power
supply lines.
•
Braided shielded cables must be used for all I/O signal cables and external encoder cables. Use
tinplated, mild steel wires for the shielding.
•
All cables, I/O wiring, and power lines connected to the Servo Drive must have clamp cores installed.
•
The shields of all cables must be directly connected to a ground plate.
*1
Not required for single-phase models with a 100-VAC input.
Note
For models with a single-phase power supply input, the main circuit power supply input terminals are L1 and
L3.
•
Use a ground plate for the frame ground for each unit, as shown in the above diagrams, and ground to
a single point.
