6-2 Analog input terminals (AVI, ACI, AUI, ACM)

Analog input signals are easily affected by external noise. Use shielded wiring and keep it as

short as possible (<20m) with proper grounding. If the noise is inductive, connecting the shield to

terminal ACM can bring improvement.

If the analog input signals are affected by noise from the AC motor drive, please connect a

capacitor and ferrite core as indicated in the following diagram.

When using contacts or switches to control the digital inputs, please use high quality components

to avoid contact bounce.

 Make sure to connect the digital outputs to the right polarity.

When connecting a relay to the digital outputs connect a surge absorber across the coil and

check the polarity.
