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
Q Q Q 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.
R R R R 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.
S S S S 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.
T T T T Use a multi-core shielding cable for the purpose of protecting
the Robot Controller from noise. Ground it to the Robot
Controller.
