The impact of electrical noise in a system is greatly reduced by following a few basic practices:Signal cabling should be 22 AWG, shielded twisted pairs.

  1. Provide adequate strain relief for all cables.
  2. Minimum cable bend radius = 4 x cable diameter.
  3. Cut the shield at the I/O device end, leave floating.
  4. Connect the shield at the Motion Control Device end earth.
  5. Ensure that all earth connections to the control cabinet are free of paint.
  6. Do not run power cabling along side signal cabling.
  7. Keep grounds as short as possible.
  8. If a secondary shield is used over the primary, tie both ends of the secondary shield to earth.
