4.5.3 I/O Signal Wiring Examples
Using a Rotary Servomotor
*1. represents twisted-pair wires.
*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 /DEC, P-OT, N-OT, /EXT1, /EXT2, and
/EXT3 input signals and the /SO1, /SO2, and /SO3 output signals. Refer to the following section for details.
6.1 I/O Signal Allocations on page 6-4
2. If you use a 24-V brake, install a separate power supply for the 24-VDC power supply from other power
supplies, such as the one for the I/O signals of the CN1 connector.
If the power supply is shared, the I/O signals may malfunction.
