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)

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: 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.
