5.2 Robot Controller I/O Circuits (NPN type)

5.2.1 User-Input, System-Input and Hand-Input Circuits (NPN type)

The following two pages show examples of the user-input, system-input, and

hand-input circuit configurations and connections of the robot controller.

The maximum allowable capacity of the robot controller's internal power source is 1.3

A. Use the internal power source within this range.

Caution  Either an external power supply type or built-in power type

Output card is available for the PLC. However, an external

power supply type requires an additional power source (24V) to

be installed. The power capacity is 15W or more.

 When controlling two or more robots with a single PLC using

the internal power source of the Robot Controller, set a PLC

Output card for each robot.

 Other than a PLC, a proximity switch, or a relay contact may be

connected directly to the input terminal of the Robot Controller.

In such a case, use the power input to pins 6 to 9 of the I/O

power connector. A two-wire photoelectric switch or proximity

switch can be connected if its leakage current is 1 mA or less.

 Use a multi-core shielding cable for the purpose of protecting

the Robot Controller from noise. Ground it to the Robot

Controller.
