14” LED LCD Monitor for CNC – OKUMA CDT14-LED

The CDT14-LED is a 14-inch LED-backlit flat-panel LCD monitor (“14-inch LED LCD Flat Panel Monitor”) manufactured by OKUMA, designed for installation on OKUMA CNC machining centres and turning centres equipped with the proprietary OSP (Open System Platform) numerical control. The unit is a direct replacement for the older cathode-ray tube (CRT) displays fitted to the same machines, maintaining mechanical and electrical compatibility with the original operator panel. It is available with standard VGA video input and industrial power supply; some variants support composite video input. The alternative part number is listed in the table below.

The monitor is the primary visual interface between the operator and the CNC controller: it displays machining programmes, machine parameters, active alarms, axis positions and cycle status. A faulty display or a degraded backlight makes it impossible to read process information, forcing an immediate machine stoppage; rapid replacement with a compatible unit is often the only alternative to extended downtime.

OKUMA Corporation is a Japanese machine tool manufacturer founded in 1898, one of the world’s leading producers of CNC lathes, vertical and horizontal machining centres and integrated manufacturing systems. OKUMA is one of the very few companies in the sector to develop both its machine tools and its own proprietary CNC controller (OSP) in-house, ensuring complete hardware and software integration. Display spare parts for machines with older-generation OSP controls are legacy / no longer in current catalogue and are available primarily as surplus, used, or through suppliers specialising in display retrofit and conversion.

Servo Drive Module – OKUMA MIP22 D-22

The MIP22 D-22 is a servo drive module (“Servo Drive Module”) manufactured by OKUMA, a leading Japanese CNC machine tool builder. The component belongs to OKUMA’s proprietary drive family, designed to integrate with the OSP (Open System Platform) CNC control series. It manages the current and speed regulation loops for servo axes, interfacing directly with the CNC controller and the machine’s AC brushless servo motors. The “D-22” suffix identifies the specific power/current variant within the MIP22 series.

The servo drive module is the core element of the axis motion system: it receives position and speed commands from the CNC, supplies the motors with the required current, and closes the position loop in real time. If it fails, the controlled axis becomes inoperative, making any machining impossible and causing an immediate machine stop with a system alarm. Replacement requires a module compatible with the specific OSP version installed on the machine.

OKUMA Corporation is one of Japan’s longest-established machine tool companies, founded in 1898 in Nagoya. Unlike many competitors, OKUMA designs and manufactures its own CNCs, motors, and drives in-house, ensuring complete hardware-software integration. Components from historical series are legacy / discontinued: availability is limited to the used market and specialist repair services.

Spindle Inverter Drive – OKUMA MIV22-3-V3

The MIV22-3-V3 (main part number MIV223V3) is an electronic spindle inverter drive (“Spindle Inverter Drive”) manufactured by OKUMA, belonging to the MIV series of power modules integrated in OKUMA CNC machining centres and lathes equipped with the OSP (Open System Platform) numerical control. The module handles the conversion of the DC bus voltage into variable-frequency, variable-voltage three-phase power for the spindle motor, operating within the machine’s drive cabinet. The V3 designation indicates the third revision of the MIV22-3 variant, potentially incorporating hardware updates over earlier versions.

The spindle inverter drive is the power electronics module that converts DC bus voltage into variable-frequency and variable-voltage three-phase power for the spindle motor. It receives speed and torque references from the OSP control and maintains stable, precise spindle rotation at any programmed speed and cutting load. Failure of this unit completely disables the spindle, preventing the machine from performing any machining operation.

OKUMA is a Japanese CNC machine tool manufacturer founded in 1898, headquartered in Oguchi, Aichi. Unlike most machine tool builders, OKUMA designs and manufactures its own CNC controls (the OSP series), motors, and drives in-house, resulting in a highly integrated and proprietary system. MIV series components are machine-specific and generally not cross-compatible with other brands; older variants are legacy / discontinued and available only as used stock or through specialist repair services.

CNC Power Supply Unit – OKUMA OPUS 5000 RHP

The OPUS 5000 RHP is an electronic power supply module for CNC control (“CNC Control Power Supply Unit”) manufactured by OKUMA, designed for the proprietary numerical control system OKUMA OPUS 5000. The unit provides the regulated DC voltages required for all electronic boards within the control: logic boards, interface boards and axis control modules. It interfaces with the CNC main control board and axis drive modules via dedicated internal connectors.

The power supply is the fundamental component of the CNC control: without stable and regulated voltages the entire control system cannot operate. A failure of this unit causes immediate machine stoppage and renders the complete control non-functional until the module is repaired or replaced. The quality of voltage regulation directly affects axis stability and machining accuracy.

OKUMA is a Japanese manufacturer founded in 1898 in Oguchi (Aichi Prefecture), specialising in CNC machine tools and proprietary control systems (OSP series). The OPUS 5000 control belongs to the 1980s–1990s generation, now legacy / discontinued, superseded by the OSP-P series: spare parts are available only as used, surplus or through specialist repair.
