4.4 I/O Signal Wiring Examples
4.4.1
Using a Rotary Servo Motor
* 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 /SI0, /SI3,
P-OT, N-OT, /EXT1, /EXT2, and /EXT3 input signals and the /SO1, /SO2,
and /SO3 output signals.
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.
