4-3 Wiring Conforming to EMC Directives
Conformance to the EMC Directives (EN 55011 Class A Group 1 (EMI) and EN 61000-6-2 (EMS))
can be ensured by wiring under the conditions described below. These conditions are for
conformance of OMNUC G-Series products to the EMC Directives.
EMC-related performance of these products, however, depends on 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 following are the requirements for EMC Directive conformance.
• The Servo Drive must be installed in a metal case (control panel). (The Servomotor does not,
however, have to be covered with a metal plate.)
• Noise filters and surge absorbers must be installed on power supply lines.
• Shielded cables must be used for all I/O signal lines and encoder lines. (Use tin-plated, mild steel
wires for the shielding.)
• All cables, I/O wiring, and power lines connected to the Servo Drive must have clamp filters
installed.
• The shields of all cables must be directly connected to a ground plate.
Wiring Method
R88D-GTA5L/-GT01L/-GT02L/-GT04L/-GT01H/-GT02H/-GT04H/-GT08H/-GT10H/
-GT15H/-GT20H/-GT30H/-GT50H
*1. For models with a single-phase power supply input (R88D-GTA5L/-GT01L/-GT02L/-GT04L/-
GT01H/-GT02H/-GT04H/-GT08H), the main circuit power supply input terminals are L1 and L3.
• Ground the motor's frame to the machine ground when the motor is on a movable shaft.
• Use a ground plate for the frame ground for each Unit, as shown in the above diagrams, and
ground to a single point.
• Use ground lines with a minimum thickness of 3.5 mm
2
, and arrange the wiring so that the ground
lines are as short as possible.
