Example of I/O Signal Connections in Position Control
Connection example in position control is as shown below.
∗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.
