About MFDLNB3SE - A6SE Panasonic A6 5000W Driver
The Panasonic MFDLNB3SE (A6SE series) is a 5000W (5.0 kW) F-Frame AC servo driver designed specifically for Position Control. As the "Basic" high-power model in the MINAS A6 lineup, it is streamlined for speed and precision using traditional pulse-train commands.
Function
- Position Control Specialist: Its primary role is to execute high-precision positioning based on pulse-train inputs from a PLC. It is the ideal choice for systems where the controller handles the path planning and the driver provides the brute force.
- Rapid Settling & Response: Features a velocity response frequency of 3.2 kHz. This functions to minimize "lag" between the controller command and the motor's actual movement, allowing for ultra-fast cycle times in heavy-duty manufacturing.
- Inertia Adaptation: Moving the massive loads associated with 5kW motors requires high stability. The driver uses real-time auto-tuning to sense the load and adjust its power output, preventing the machine from shaking or "hunting" for its position.
- Mechanical Protection: Uses digital notch filters to identify and "cancel out" the resonance frequency of your machine frame, ensuring a longer lifespan for bearings and gears.

Physical Dimensions & Weight (Inches & Lbs)
Converted for the heavy-duty F-Frame chassis:
- Weight: Approximately 11.46 lbs (5.2 kg).
- Width: 5.12 inches (130 mm).
- Height: 8.66 inches (220 mm).
- Depth: 8.50 inches (216 mm).
Key Limitation: The "SE" model does not support analog speed control, Modbus/EtherCAT networking, or the STO safety function. It is purely for point-to-point pulse positioning.
The primary function of the Panasonic MFDLNB3SE is to act as a high-power positioning actuator for 5.0 kW motors. It is a "Position-Only" specialist designed to follow pulse commands from a PLC with extreme reliability and high electrical current.
1. Dedicated Position Control (Pulse Train)
The "SE" series is functionally streamlined for Pulse Train Input.
- The Power Follower: Its main job is to listen to high-speed pulses sent by a motion controller or PLC. For every pulse it receives, it moves the massive 5.0 kW motor exactly one increment.
- Cost-Effective Simplicity: By focusing strictly on pulse positioning, it provides a stable and straightforward solution for standard point-to-point tasks without the complexity (or cost) of network programming.
2. Massive Electrical Power Conversion
It functions as the heavy-duty power stage for the 5.0 kW motor class.
- High Current Delivery: It takes standard 3-phase industrial power and converts it into precise, high-current electrical waves (up to 119A peak) required to move several hundred kilograms of machinery with high acceleration.
3. Real-Time Dynamic Correction
The driver acts as an "active stabilizer" for high-mass loads:
- 3.2 kHz Velocity Response: It calculates the motor's position 3,200 times per second. If a heavy load causes the motor to lag or try to "overshoot" its target, the driver instantly corrects the power output to keep it perfectly on track.
- Inertia Adaptation: 5.0 kW motors move huge loads. The MFDLNB3SE automatically senses the weight of the load and adjusts its internal "stiffness" (gain) so the machine doesn't shake or vibrate when it starts or stops.
4. Mechanical Protection (Resonance Suppression)
At 5.0 kW, mechanical vibration can be destructive. The driver functions as a digital shock absorber:
- Adaptive Notch Filters: It identifies the specific "hum" or vibration frequency of your machine frame and electronically cancels it out. This allows you to run the machine at much higher speeds than would otherwise be possible without mechanical damage.
5. High-Resolution Feedback Interface
- It processes the 23-bit encoder data (8.38 million pulses per turn) coming from the motor. This ensures the main controller always knows the exact location of the machine at all times, even when under high stress.
