5.2.3User-Output, System-Output, and Hand-Output Circuits (NPN type)

The following two pages show an example of the configuration and connection of the Robot Controller's user-input output, system-output and hand-output circuit.

Since the initial resistance of a lamp is small, the output circuit may be damaged by rush current that flows when the lamp lights.

When directly turning ON and OFF a lamp, use a lamp whose rating is 0.5W or less.

To reduce rush current, select and connect a resistor R that allows dark current 1/3 or less of the rated current to flow when the lamp goes OFF.

An example of connecting a lamp is shown on page 121.

(1)The User-Output, System-Output and Hand-Output Circuit are open collector output circuits.

(2)The maximum allowable source current is 70 mA.

Keep the current consumption of a device to be connected to the Robot Controller, such as a PLC and a relay coil, below the allowable current.

(3)Select an induction load, such as a relay coil, which has a built-in diode (for absorbing inverse electromotive force).

To use an induction load without a built-in diode, add a diode equivalent to the 1S1888 (Toshiba) in close vicinity to the coil.

Caution: When externally attaching a diode, connect it with correct polarity. Incorrect polarity may damage the Output circuit.

(4) Connecting a lamp requires a circuit through which dark current flows.

Caution: Since the initial resistance of a lamp is small, the output circuit may be damaged by rush current that flows when the lamp lights.

Refer to page 121.

(5)When using the internal power source, prepare a PLC input circuit unit that does not contain a power source.

Caution: Keep the total current capacity of the internal power source below 1.3A.

(6)Use a multi-core shielding cable for the purpose of protecting the devices from external noise. Ground it to the robot controller.

(7)+24V internal power source of the robot controller must not be grounded.

Caution: If the output terminal +24V of internal power source is grounded, there may be a case where the controller is damaged.
