I/O Signal Wiring Examples

Using a Rotary Servomotor
Overheat Protection Input
Sequence Input Signal Power Supply Input
CCW Drive Prohibit Input (prohibited when OFF)
CW Drive Prohibit Input (prohibited when OFF)
Origin Signal Input (LS active when ON)
External Stop Input (OFF to stop)
*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: If you use a 24-V brake, install a separate power supply for the 24-VDC power supply from other power sup-
plies, 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.
