* 1. represents twisted-pair wires.
* 2. The time constant for the primary filter is 47 µs.
* 3. Connect a backup battery when using an absolute encoder. When connecting a battery to the host controller,
however, do not connect a backup battery.
* 4. Enabled by the parameter setting.
* 5. Customers must purchase a 24 VDC power supply with double-shielded enclosure.
* 6. Enabled when using the absolute encoder.
Note: The functions allocated to the input signals SI0 to SI6 and the output signals SO1 to SO3 can be changed by
using the parameters. Refer to 7.3.2 Input Circuit Signal Allocation and 7.3.3 Output Circuit Signal Alloca-
tion.
