Communication Setting
When changing communication address via the Power/Comm. terminal, resupply the power.
Set the communication address by the communication address setting switch (SW1) and Communication address group switch (SW2).
When setting as 0, it does not operate communication.
(setting range: 01 to 31, factory default: [SW1] 1, [SW2] +0)
It is for parameter setting and monitoring via external devices (PC, PLC, etc.).
