3. I/O Polarity
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. The I/O polarity can be confirmed by checking the nameplate affixed to the rear of the
robot.
3.1 I/O Polarity
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 by the I/O nameplate.
1. I/O Polarity
• NPN (sink type)
• PNP (source type)
2. I/O Power Supply Indication
• External
The power supply (DC24V) for a device connected to the I/O-SYS is externally supplied. 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
connector.
NOTE
I/O power supply specifications (External/Internal) are selected when you purchase the robot and
cannot be changed after doing so.
For further information regarding wiring, please refer to the operation manual External Control (I/O /
Fieldbus).
