AC Brushless Servo Motor – PANASONIC MSMA082A1C
The MSMA082A1C is an AC brushless servo motor rated at 750 W, belonging to the MINAS A series by Panasonic Industrial Devices. The part number decodes as: MSMA family (high-inertia motors, 80 mm frame), 750 W, 200 V AC supply, integrated incremental encoder at 2,500 pulses/rev, and standard mechanical configuration with keyed shaft (suffix “A1C”). It is compatible with Panasonic MSDA and MSD series drives (MINAS A) and is documented on machining centres, CNC milling machines and axis drive systems from various machine-tool builders.
The servo motor is the electromechanical actuator that converts the CNC position or speed reference into real axis movement: it delivers precise, responsive torque thanks to continuous real-time feedback from its built-in encoder. If it fails — due to a winding fault, damaged encoder or worn bearings — the affected axis loses control, the CNC raises a following-error alarm and production stops immediately.
Panasonic Industrial Devices & Solutions (formerly Matsushita Electric Industrial, renamed Panasonic Corporation in 2008) has produced the MINAS servo line since 1991. Current series MINAS A5 and A6 use high-resolution serial encoders (17 bit, 131,072 p/r); the MINAS A (MSMA) series with 2,500 p/r incremental encoder is therefore legacy / discontinued, still widespread in the installed base but available only as used stock, surplus or through specialist repair.

AC Servo Amplifier – PANASONIC MSDA083A1A
The MSDA083A1A is an AC servo amplifier (“AC Servo Amplifier”) from the MINAS A series, manufactured by Panasonic (Industrial Automation Division, formerly Matsushita Electric Works). It is designed for precise control of AC brushless motors in the MSM082 Panasonic family and is rated in size 083, compatible with ~750 W motors. The power supply is single-phase 100 V AC, 50/60 Hz (suffix A1); control is achieved via analogue ±10 V reference or pulse train (Pulse/Dir or CW/CCW). Feedback is handled by an incremental encoder mounted on the motor. The drive is documented in applications on CNC machine tools, industrial robots, and process automation equipment.
The servo amplifier is the power and regulation module that converts the position or velocity reference from the CNC into PWM-modulated three-phase current for the brushless motor: it closes the current, speed, and position loops in real time, ensuring precise and stable dynamic response. In the event of failure, the axis or function driven by this unit loses all control, causing immediate machine stoppage and preventing any resumption of the machining process until the unit is replaced or repaired.
Panasonic (formerly Matsushita Electric Works) is one of the world’s leading manufacturers of AC servo systems, with the MINAS product line available since the 1990s. The MINAS A series has been progressively superseded by the MINAS A5 and subsequently A6 series; products in the original MSDA family are therefore legacy / discontinued, available only as used, NOS (New Old Stock), or through specialist repair services.

AC Servo Drive – PANASONIC MSD3A3P1EB
The MSD3A3P1EB is an AC servo amplifier (“AC Servo Drive”) manufactured by Panasonic (formerly Matsushita Electric), belonging to the MINAS series. Designed for closed-loop control of AC permanent-magnet synchronous servo motors, it targets CNC and industrial automation applications. The part number identifies a single-phase variant with an rated current of ~3 A, suitable for motors in the 200–400 W power range. It is neither a PLC nor a standalone CNC controller, but a dedicated amplifier managing the servo motor regulation loops. The EB suffix denotes a variant intended for the European/international market.
The AC servo drive closes the current, speed, and position loops on the servo motor: it receives positioning references from the CNC and generates the current required for the motor to reach and hold the programmed position with maximum precision. A drive failure completely disables the controlled axis; the absence of feedback or motor power triggers an immediate alarm and machine stop, making any machining operation impossible until the unit is replaced or repaired.
Panasonic (formerly Matsushita Electric Works) is one of the world’s leading manufacturers of industrial motion control systems. The MINAS family of AC servo amplifiers and motors has been a mainstay of industrial automation for over thirty years, evolving from the MSD series through to the current MINAS A6/A6N. All MSD-series models are legacy / discontinued: available only as used stock, NOS, or through specialist repair services.

AC Servo Drive – PANASONIC MSD011P1EC03
The MSD011P1EC03 is a 100 W single-phase AC servo drive (“AC Servo Drive”) manufactured by Panasonic, belonging to the MINAS family. The part number identifies a drive with single-phase AC input, EC-type encoder interface, and revision 03. Designed for the control of AC brushless servo motors, it is documented on CNC machining centres, CNC turning centres, and multi-axis industrial automation systems.
The AC servo drive is the power and control unit that receives position, speed, or torque references from the CNC controller and drives the servo motor with high precision through a sinusoidal PWM regulation loop. In the event of failure, the corresponding machine axis loses motion control: CNC program execution is interrupted and the machine stops in alarm, making any operation on the affected axis impossible.
Panasonic Corporation (formerly Matsushita Electric Industrial Co., Ltd.), founded in 1918 in Osaka, Japan, is one of the world’s leading manufacturers of industrial and consumer electronics. The Factory Automation division produces the MINAS series of servo drives and servo motors, currently in its A6 generation. Products in the MSD series belong to earlier generations and are to be considered legacy / discontinued, superseded by the A4, A5, and A6 families.

CNC Axis Servo Drive – PANASONIC DV88010LDM04
The DV88010LDM04 is an AC servo drive / servo amplifier for CNC axis control manufactured by Panasonic, belonging to the servo drive range for CNC machine tools. The unit manages closed-loop speed, position, and torque control of the axis servo motor, receiving references from the numerical control and driving the AC power stage accordingly. The prefix DV identifies the drive family within Panasonic’s nomenclature; the numeric and alphanumeric suffixes indicate variants of rated power, supply voltage, and encoder feedback type.
The servo drive is the core of the axis control system: it receives position or speed commands from the CNC, regulates motor current in real time, and guarantees accuracy and repeatability in machine axis movements. A drive failure causes immediate shutdown of the controlled axis, resulting in a machine halt; in multi-axis systems, a single failed drive prevents any machining cycle from running.
Panasonic is one of the world’s leading manufacturers of industrial motion control systems through its Panasonic Industry division (formerly Panasonic Electric Works). The MINAS servo range and earlier series are widely deployed in machine tools, robotics, and industrial automation. Models in the DV88 series belong to an older generation: official technical support availability should be verified, as several codes in this family are legacy / discontinued.
