represents twisted-pair wires.
*2.
The 24-VDC power supply is not provided by Yaskawa. Use a 24-VDC power supply with double insulation or
reinforced insulation.
*3.
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.
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.
