✔
Use metallic materials for the door and main body of control panel.
✔
Use EMI gasket so that there is zero clearance between the door and control panel. Install EMI gasket
uniformly to the contact points between door and main body of control panel to confirm their conductivity.
✔
Ground noise filter frame to control panel.
✔
Use shield cables for motor power line and encoder cable. Clamp grounding of shield at the frame of
control panel and equipment.
✔
Use conducting metal P-clip or U-clip to ground and clamp shielded wire, and fix it directly with metal
screws. Do not ground by soldering electric wire to shielded wire.
✔
Wire servo amplifier at a short distance from the secondary side of noise filter, and wire the primary side
and secondary side of noise filter separately.
