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.
Digital inputs (FWD, REV, MI1~MI8, COM)
When using contacts or switches to control the digital inputs, please use high quality components
to avoid contact bounce.
The "COM" terminal is the common side of the photo-coupler. Any of wiring method, the "common
point" of all photo-coupler must be the "COM".
