Core Features & Benefits
High-Speed Frequency Response
The MINAS A Series incorporates Panasonic's unique algorithm, achieving a
500 Hz speed frequency response - twice that of previous products. Positioning settling time is shortened to 1/4 of conventional models.
Middle Inertia Design
The MDMA102A1G features a
middle inertia rotor (26.0 × 10⁻⁴ kg*m²), specifically optimized for general-purpose automation applications requiring balanced performance between rapid acceleration and stable load handling.
300% Overload Capacity
With a peak torque of 14.4 N*m (300% of rated torque), this motor handles demanding acceleration requirements and sudden load fluctuations without stalling.
- Resonance Suppression & Vibration Control: Advanced functions compensate for mechanical rigidity deficiencies, enabling high-speed positioning even with less rigid mechanical systems.
- Full Closed-Loop Control Capability: By connecting an external high-precision linear scale, the system can be configured for full closed-loop control, further improving positioning accuracy.
- Built-in FFT Frequency Analysis: The built-in FFT (Fast Fourier Transform) function detects mechanical resonance points, facilitating system adjustment and tuning.
- Auto-Tuning Functions: Two auto-tuning methods available: standard auto-tuning for general applications and real-time auto-tuning for continuous gain adjustment.
- Multi-Axis Communication: Equipped with RS485 and RS232C communication ports, enabling control of up to 16 axes simultaneously.
- IP65 Environmental Protection: Rated IP65 (with oil-resistant cylindrical connectors), protected against dust ingress and low-pressure water jets.
- Multiple Encoder Options: Supports various encoder types including standard 2500 P/R incremental, high-precision 17-bit incremental, and 17-bit absolute encoder.
Applications
- General Automation Machinery: Assembly lines, pick-and-place systems, and indexing drives
- Material Handling: Conveyor systems, palletizers, and automated storage/retrieval systems
- Packaging Machinery: Wrapping, filling, and labeling equipment requiring precise torque control
- Textile Machinery: Spinning, winding, and yarn tension control systems
- Machine Tools: Feed axis drives for milling, turning, and grinding equipment
- Robotics: Medium-sized robot arms and articulated joints
- Semiconductor Equipment: Wafer handling and inspection systems
- CNC Machinery: Routers, engraving machines, and plasma cutters
Replacement & Upgrade Options
Note: The MDMA102A1G has been discontinued (September 30, 2011). Panasonic recommends checking the "AC Servo Motors (Discontinued Products)" page for recommended substitutes.

Recommendation |
| For New Designs |
Upgrade to MINAS A6 or A7 series (23-bit/32-bit absolute encoders, EtherCAT/RTEX communication) |
| For Legacy System Repair |
Source new old stock (NOS) or refurbished MDMA102A1G units |
| For Retrofit Projects |
Consult Panasonic technical support for application-specific replacement guidance |
Key Differences with Newer Series
- A6/A7 series offer up to 27-bit/32-bit encoder resolution (vs. 2500 P/R incremental)
- Enhanced vibration suppression and auto-tuning capabilities
- STO (Safe Torque Off) safety function available
- EtherCAT and RTEX network communication options
- PANATERM software support for setup and tuning
