5.2Robot 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 Q 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.

RWhen 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.

SOther 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.

TUse a multi-core shielding cable for the purpose of protecting the Robot Controller from noise. Ground it to the Robot Controller.
