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.
Consideration
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
