∗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.
Refer to 3.4.1 Input Signal Allocations and 3.4.2 Output Signal Allocations.
