3.4 External input/output
3.4.1 Types
(1) Dedicated input/output...............................These inputs and outputs carry out the robot remote operation and
status display.
(2) General-purpose input/output.................These are inputs and outputs that the customer can program for
peripheral device control.
Moreover, it is possible to use parallel input/
output units and input/output signals via CC-Link.
(3) Hand input/output.........................................These are inputs and outputs related to the hand that the customer
can program. (The hand output is an option. The

matic hand interface" is required.)
3.4.2 Explanation
The parallel input/output unit uses connector bridging. Purchase the "External I/O cable" for connection with
external devices.
The hand output is an option. Refer to Page 67, "(2) Pneumatic hand interface" for details
The parallel input/output unit can be expanded outside of the controller.
The expansion parallel input/output unit is connected with the control unit in the controller using a robot I/O link
cable. Parallel input and output units can be expand as an option to seven maximums. With allows up to input 256
points and output 256 points of maximums can be used including 32 points input and 32 points output of standard.
Refer to Page 70, "(3) Parallel I/O unit" for details on the parallel input/output unit.
