7. I/O-SYS
There are system functions assigned to I/O-SYS. For information regarding the assigned functions,
refer to “8. I/O-SYS Function Assignment.”
7.1 Connectors
There are two types of I/O polarity: NPN specifications and PNP specifications. After confirming your
robot’s polarity specifications, always connect tools (etc.) which are compatible with these
specifications.
I/O Polarity
If you are connecting external devices, please make sure they are compatible with your robot’s I/O
polarity. The robot’s I/O polarity can be confirmed on the I/O nameplate.
I/O Power Supply Indication
• External
The power supply (DC24V) for a device connected to the I/O-SYS is supplied externally.
Please prepare a separate I/O power supply.
• Internal
The power supply (DC24V) for a device connected to the I/O-SYS is output from the I/O-SYS

NOTE: I/O power supply specifications (External/Internal) are selected when you purchase the
