Analog input terminals (AVI1, AVI2, ACI, ACM)
 Analog input signals are easily affected by external noise. Use shielded wiring and
keep it as short as possible (< 20 m) with proper grounding. If the noise is inductive,
connecting the shield to terminal ACM can bring improvement.
 When using analog input signal in the circuit, twisted pair is suggested to use for
dealing with weak signal.
 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.
Figure 6-1
Digital inputs (FWD, REV, MI1–MI8, COM)
 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”.
