Example of I/O Signal Connections
The following diagram shows a typical connection example.
∗1.
represents twisted-pair wires.
∗2.
Connect when using an absolute encoder. When the encoder cable with the battery case is connected, do not connect
a backup battery.
∗3.
The 24-VDC power supply is not included. Use a 24-VDC power supply with double insulation or reinforced insula-
tion.
∗4.
Always use line receivers to receive the output signals.
Note: The functions allocated to the input signals /DEC, P-OT, N-OT, /SI0, and /SI4 to /SI6 and the output signals /SO1,
/SO2, and /SO3 can be changed by using the parameters.
