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 diagrams:

ACI/AUI1/AUI2
ACM
ferrite core
wind each wires 3 times or more around the core
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.
Digital outputs (MO1, MO2, MCM)
Make sure to connect the digital outputs to the right polarity, see wiring diagrams.
When connecting a relay to the digital outputs, connect a surge absorber or fly-back
diode across the coil and check the polarity.
