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.
– You can use parameters to change the functions allocated to the /
SI0, /SI6, P-OT, N-OT, /EXT1, /EXT2, and /DEC input signals and
the /SO1, /SO2, and /SO3 output signals.
Ä Chap. 7.2 ‘I/O Signal Allocations’ page 196
– 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.
