Improving Encoder Cable Noise Resistance
Take the following steps during wiring and installation to improve the encoder's noise
resistance.
 Always use the specified encoder cables.
 If cables are joined midway, be sure to use connectors. And do not remove more than 50 mm of
the cable insulation. In addition, always use shielded cables.
 Do not roll cables. If cables are long and are rolled, mutual induction and inductance will increase
and cause malfunctions. Always use cables fully extended.
 When installing noise filters for encoder cables, use clamp filters.
 The following table shows the recommended clamp filters.
NEC TOKIN
TDK
 Do not place the encoder cable with the following cables in the same duct.
