analog inpuTs
•
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, connect the shield to terminal
ACM�
•
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�
(Wind each wire around the core 3 times or more�)

•
When using contacts or switches to control the digital inputs, use high quality components to
avoid contact bounce�
TransisTor ouTpuTs
•
Make sure to connect the digital outputs to the correct polarity�
•
When connecting a relay to the digital outputs, connect a surge absorber across the coil and
check the polarity�
analog ouTpuTs
•
When setting SW1, and using it as a current source (external 500Ω resistor is required), ensure
P4.53 AO1 0~20mA/4~20mA selection is set appropriately�
•
When seting SW2 to 0/4~20mA ensure to set P4.57 AO2 0~20mA/4~20mA selection
appropriately� When setting to 0~10V (or leaving as default) ensure P4�57 is set to zero�
