Panasonic MDDLN45NE 1.5kW Servo Driver with 23-bit Encoder RTEX Network and 3.2 kHz Frequency Response

The Panasonic MDDLN45NE is a high-performance AC servo driver from the MINAS A6N Series, featuring Realtime Express (RTEX) high-speed network communication. This D-Frame driver is designed for applications requiring deterministic real-time control and high-precision positioning in multi-axis systems.

As part of the A6NE series (Basic Type), the MDDLN45NE delivers exceptional value for industrial automation OEMs and system integrators. It combines Panasonic's industry-leading 23-bit absolute encoder support with a 3.2 kHz frequency response, enabling ultra-smooth motor control and rapid settling times.

Product Status: Active - In Production

The MDDLN45NE features Panasonic's proprietary RTEX (Realtime Express) communication protocol, a high-speed motion network developed for precise real-time performance required for advanced servo control. This enables:

• Deterministic control cycles for multi-axis synchronization
• Real-time transmission of operation commands, parameter settings, and status monitoring
• Reduced wiring complexity compared to pulse-based systems

With support for 23-bit (8,388,608 resolution) absolute encoders, the MDDLN45NE delivers exceptional positioning accuracy and ultra-smooth motion at both high and low speeds. The encoder can also be configured for incremental operation without a battery by setting parameter Pr.0.15 to "1".

The driver supports three primary control modes switchable via RTEX communication:

• Position Control (PP/CP): Ideal for precision positioning applications
• Velocity Control (CV): Suitable for speed-controlled processes
• Torque Control (CT): Perfect for tension control and force-sensitive applications

The 3.2 kHz frequency response enables rapid command following and quick settling times, improving machine throughput and dynamic performance.

The driver accepts both single-phase and 3-phase 200VAC input, providing installation flexibility across different facility configurations.

An integrated regenerative resistor handles deceleration energy, with support for external resistors for high-inertia applications.

Rated for operation from 0°C to 55°C, the MDDLN45NE is built for demanding industrial environments.

The Panasonic MDDLN45NE is engineered for high-performance industrial automation applications requiring real-time network control:

• Multi-Axis Motion Systems: RTEX network enables coordinated control of multiple axes for robotics and gantry systems
• Pick-and-Place Machines: High-speed positioning with 3.2 kHz frequency response
• CNC Machine Tools: Precision axis control with 23-bit encoder feedback
• Packaging Machinery: Synchronized motion for wrapping, filling, and labeling equipment
• Textile Machinery: High-speed winding and tension control applications
• Electronic Assembly: PCB assembly and semiconductor manufacturing equipment
• Material Handling: Conveyor systems, palletizers, and automated guided vehicles (AGVs)
• General Factory Automation: Any application requiring deterministic real-time servo control

The MDDLN45NE is designed for use with Panasonic MINAS A6 Series servo motors. For optimal performance, pair with motors featuring 23-bit absolute encoders in the 1.0kW to 1.5kW power range.

• RTEX Network: Use CAT5e or higher Ethernet cables for daisy-chain or star topology connections
• USB Interface: Connect to PC for parameter configuration using PANATERM software

• PANATERM Ver.7.0+: Parameter setting, real-time monitoring, and auto-tuning
• RTEX Communication Protocol: For master controller integration

The 23-bit (8,388,608 ppr) encoder provides significantly higher resolution than standard 17-bit or incremental encoders, enabling smoother motion at low speeds and finer positioning accuracy.

Panasonic is a global leader in industrial automation with decades of servo technology expertise. The MINAS A6 series is trusted worldwide for its robust design and consistent performance.

RTEX offers deterministic real-time control at a lower cost than some competing industrial Ethernet protocols, making it an excellent value for multi-axis systems.
