* 1.
* 2. Connect these when using an absolute encoder. If the Encoder Cable with a Battery Case
is connected, do not connect a backup battery.
* 3. The 24-VDC power supply is not provided by Yaskawa. Use a 24-VDC power supply with
double insulation or reinforced insulation.
* 4. Always use line receivers to receive the output signals.
Note: 1. You can use parameters to change the functions allocated to the /SI0, /SI3,
2. If you use a 24-V brake, install a separate power supply for the 24-VDC
