9″ Monochrome CRT Monitor – FANUC A61L-0001-0093

The A61L-0001-0093 is a 9″ monochrome CRT monitor (“9-inch Monochrome CRT Display”) manufactured by FANUC, used as the standard operator display unit in FANUC CNC Series 0, Series 6, Series 10/11/12 and Series 15 control systems. The monochrome phosphor cathode ray tube display (typically green P31 or amber P39) renders the CNC operator interface: active programs, machine status, alarm messages and axis coordinates. It connects to the control unit via the dedicated video board housed in the FANUC cabinet. It carries no independent CNC logic and is a pure display peripheral.

The CRT monitor is the primary operator interface of the numerical control: without it the operator cannot view the running program, read alarm messages, check axis coordinates or interact with the CNC through the keypad. A failed monitor renders the machine operationally unusable, blocking all production, diagnostic and setup activities and causing an immediate production stoppage.

FANUC is the world leader in CNC systems, industrial robots and factory automation, founded in Japan in 1956 as a Fujitsu division and independent since 1972. This monitor belongs to the classic display line for CNC systems of the 1980s–1990s and is legacy / discontinued: available only as used, surplus stock or through specialist CRT repair services and LCD retrofit kits.

14″ Colour CRT Monitor – FANUC A61L-0001-0074

The A61L-0001-0074 is a 14″ colour cathode-ray tube (CRT) monitor (“14″ Colour CRT Monitor”) manufactured by FANUC, used as the integrated display unit in MDI/CRT operator consoles of FANUC Series 0, Series 6, Series 10/11/12, Series 15 and Series 16/18/21 CNC systems, as well as selected FANUC robot cells of the same era. The unit receives the video signal from the control unit via dedicated cabling and a proprietary connector, rendering all CNC operator screens in colour CRT technology. No distinct hardware revisions with separate part numbers are documented; production batches may differ only in minor internal components.

The monitor is the primary visual interface between the operator and the CNC system: without it, it is impossible to view part programmes, machine parameters, diagnostics, or alarm messages. A monitor fault effectively halts machine operation even when the control electronics are fully intact, making it impossible to interact with menus, reset alarms, or modify critical parameters.

FANUC (Fuji Automatic NUmerical Control) is the world’s leading manufacturer of CNC systems and industrial robotics, headquartered in Oshino, Yamanashi, Japan. Founded in 1956 as a division of Fujitsu and independent since 1972, FANUC holds the highest global market share in the CNC sector. CRT monitors of the A61L family are legacy / discontinued: CRT technology is no longer manufactured industrially and these components are available exclusively as used, surplus, or via replacement with compatible LCD retrofit kits.

AC Spindle Drive – FUJI FMD-11AC-21A

The FMD-11AC-21A is an AC spindle drive (“AC Spindle Drive”) from the FRENIC 5000M2 series by Fuji Electric. Designed specifically for vector speed and torque control of AC spindle motors on CNC machine tools, it sits between the mains supply and the spindle motor, converting fixed mains voltage into variable voltage and frequency. The prefix FMD identifies the spindle drive family within the FRENIC 5000M2 series; the numeric designation encodes the power class (~11 kW), AC indicates alternating-current technology, and 21A specifies the voltage variant (200 V class) and hardware revision. The unit may exist in multiple revisions and variants; option modules such as serial communication boards, EMI filters and encoder interface cards were available as separate accessories.

The AC spindle drive is the electronic core of the spindle speed control system in the machine tool: it receives the speed reference from the CNC, closes the speed and torque loop via encoder or tachogenerator feedback, and supplies the motor with the power required to hold the programmed speed constant under varying cutting loads. Failure of this unit causes immediate spindle shutdown and total machine downtime: no machining is possible until the drive is replaced or repaired, with consequent production losses and risk of scrapped workpieces.

Fuji Electric is a Japanese industrial group founded in 1923 and a world leader in the design and manufacture of AC/DC drives, inverters and industrial automation systems for precision applications. The FRENIC 5000M2 series belongs to the generation of CNC machine-tool spindle drives from the 1990s–2000s and is now legacy / discontinued: spare units are available only as used, NOS surplus, or through specialist repair centres.

Main Technical Specifications

Positioning Control Board – FUJI EP-3358C-C

The EP-3358C-C is an electronic positioning control board (“Positioning Control Board”) manufactured by FUJI Electric, designed for use in CNC systems and industrial automation equipment of the same make. The board handles axis position control and feedback processing from encoders or resolvers, interfacing with the servo drives within the same control system. It is not a CPU or generic I/O module, but a dedicated unit for precise machine axis positioning.

The positioning board is the electronic module that closes the position loop in the CNC system: it processes axis encoder feedback signals, calculates position error, and generates correction references for the servo drives. Without it, precise axis positioning is impossible: any machining operation requiring tight geometric tolerances would produce out-of-tolerance parts or risk collisions due to position reference errors.

FUJI Electric is a Japanese manufacturer with over a century of history in industrial electronics, founded in 1923 as a joint venture between Furukawa Electric and Siemens. Specialised in power electronics, drives, CNC systems and factory automation (FA), its product lines include the FRENIC inverter series and Alpha servo systems. Products in the EP-3358C-C family belong to a legacy / discontinued generation of controls and are available only as used units, NOS stock, or through specialist repair services.

Main Technical Specifications

Axis Positioning Control Board – FUJI EP-3308D-C

The EP-3308D-C is an electronic axis positioning control board (“Axis Positioning Control Board”) manufactured by FUJI Electric, belonging to the numerical control and industrial automation product family of the same manufacturer.

The series identifier EP-3308 designates the board family within FUJI’s positioning control range for this generation; the suffix identifies variant D and revision C.

The axis positioning board is the central element of motion control: it receives position commands from the CNC processor, compares them with the feedback signal (encoder or resolver), and calculates the following error to continuously correct the axis trajectory. Without this board, the CNC system loses complete control of the axes: any movement becomes uncontrolled, with consequent risk of collision, dimensional rejection of the workpiece, or serious mechanical damage to the machine.

FUJI Electric is a Japanese industrial group founded in 1923, with strong specialisation in power electronics, inverters, drives, CNC systems and industrial automation. Historically present in the machine tool market with proprietary axis control systems, the group has progressively oriented its offering towards new-generation integrated solutions.
