15.16 General purpose I/O board
Four digital I/O connectors for the robot general purpose I/O are provided 40 inputs and 40
outputs.
The I/Os are divided into two types: general purpose I/O and specific I/O.The I/O
assignment differs depending on the application. Specific I/O is a signal in which the part is
decided in advance. Specific I/O is used when the external operation equipment such as
positioner controller and centralized controller control the robot and related equipment as a
system. General-purpose I/O are mainly used as timing signals for the manipulator and
peripheral devices in JOBs that require robot motion.
Refer to chapter “General purpose I/O signal assignment” for more details on signal
allocation.
For the connection of the robot’s general purpose I/O signal connectors, and the I/O signal
related to start and stop, refer to “Connection wire with robot general purpose I/O Connector
(CN306, 307, 308, 309)”and “Specific I/O signal related to start and stop”.
• Connection wire with robot general purpose I/O connector (CN306, 307, 308, 309)
Please refer to the figure below when manufacturing the cable connection with robot
general purpose I/O connector (CN306, 307, 308, 309) of I/O unit. Unshielded twisted pair
cable must be used (the cable side connector and the I/O terminal block are the options).
