Precautions for EMC Directives
Use the following guidelines below for the RS1 servo system in order to conform the customer’s
equipment and devices to the EMC Directives.
①
A metallic material must be used for the door and main body of control panel.
②
The joints of the top and side panels must be masked and welded.
③
Parts joined with screws must be welded to prevent noise from leaking out from joints.
④
When joining parts with screws or spot welding, the welding space must be within 10cm.
⑤
Use an EMI gasket so that there is zero clearance between the door and control panel.
⑥
Install EMI gasket uniformly to the contact points between door and main body of control panel.
⑦
Perform conductivity processing on the EMI gasket, door and main body of control panel to
confirm their conductivty.
⑧
Ground the noise filter frame to the control panel.
⑨
Ground the servo amplifier chassis provided by the customer.
⑩
Use shield cables for the motor power line and sensor cable.
⑪
Ground the shield of motor power wire and sensor cable to the control panel with the clamp.
⑫
Ground and clamp the shield of motor power line and sensor cable to the frame of the servo
amplifier.
⑬
Use a conducting metal P clip or U clip to ground and clamp the shield wire, and fix it directly
with metal screws. Do not ground by soldering electric wire to the shield wire.
⑭
Wrap the zero-phase reactor four times around the primary side of the noise filter.
⑮
Wire the servo amplifier at a short distance from the secondary side of noise filter.
⑯
Wire the primary side and secondary side of the noise filter separately.
