A20B-2100-0770 - Operator Panel PC Board - FANUC
This FANUC reference board A20B-2100-0770 is used for FANUC R-j3iB robots.
LED: communication status with the main board
OFF Communication error
PON: Illuminates normally when the internal power supply of the panel board produces + 5V.
This FANUC control board is sold with a guarantee of operation.
- Main board
The main board contains a microprocessor, its peripheral circuits, memory, and operator panel control circuit. The main CPU controls servo mechanism positioning and servo amplifier voltages.
- Battery retains main board memory when controller power is off.
- I/O printed circuit board, FANUC I/O Unit MODEL--A
Various types of printed circuit boards are provided for applications including process I/O. The FANUC I/O unit MODEL-A can also be installed. When it is used, various I/O types can be selected. These are connected with FANUC I/O Link.
- E--stop unit
This unit controls the emergency stop system with control reliable E--stop performance criteria for both of the magnetic contactor and the precharge of the servo amplifier.
- Power supply unit
The power supply unit converts theAC power to various levels of DC power.
- Backplane printed circuit board
The various control printed circuit boards are mounted on the backplane printed circuit board.
- Teach pendant
All operations including robot programming are performed with this unit. The controller status and data are indicated on the liquid-crystal display (LCD) on the pendant.
- Servo amplifier
The servo amplifier controls servomotor power, pulse coder, brake control, overtravel and hand broken.
- Operator panel
Buttons and LEDs on the operator panel are used to start the robot and to indicate the robot status. The panel has a port for the serial interface to an external device and an interface to connect thememory card for data backup. It also controls the emergency stop control circuit.
The supply voltage is converted to an AC voltage required for the controller by the transformer.
- Fan unit, heat exchanger
These components cool the inside of the control unit.
- Circuit breaker
If the electric system in the controller malfunctions, or if abnormal input power causes high current in the system, the input power is connected to the circuit breaker to protect the equipment.
- Regenerative resistor
To discharge the counter electromotive force from the servomotor, connect a regenerative resistor to the servo amplifier.
FANUC is a Japanese manufacturer of industrial robots, machining centers and numerical controls for machine tools
Since its creation in 1956, when the company’s founder, Dr. Seiuemon Inaba, introduced the concept of digital controls, FANUC has always been at the forefront of manufacturing techniques in the world. Moving from the automation of a single machine in the late 1950s to the automation of entire production lines over the following decades.
