*1 For the wire, use the 2-core twisted cable.
*2 These values indicate the input resistance of the R60ADV8.
*3 Connect the AG terminal and the GND of the external device if there is a potential difference between them.
*4 Be sure to ground the shield wire of cables on each channel and the FG terminal.

*1 For the wire, use the 2-core twisted cable.
*2 These values indicate the input resistance of the R60ADI8.

*4 Be sure to ground the shield wire of cables on each channel and the FG terminal.
Establish a connection of the FG terminal of the power supply module.
In the R60AD4 and R60ADV8, If the circuit is left open between terminals of unused channels, enabling A/D
conversion may generate an undefined digital value. To prevent this phenomenon, take any of the following
measures:
• Set the A/D conversion enable/disable setting in the unused channels to disable the A/D conversion. Note
that changing the A/D conversion enable/disable setting from A/D conversion enable to A/D conversion
disable causes a shorter sampling cycle.
• Short-circuit the input terminals (V+) and (V-) in the unused channels.
