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.

Transistor outputs (MO1, MO2, MCM)

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.

Remove the Terminal Block

1. Loosen the screws by screwdriver. (As shown in figure below).
2. Remove the control board by pulling it out for a distance 6~8 cm (as 1 in the figure) then lift the control
board upward(as 2 in the figure).
