ACM Analog Signal Common Common for analog terminals
NOTE: Wire size of analog control signals: 18 AWG (0.75 mm
2
) with shielded wire
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.
