The Panasonic MFDLTB3SF (A6SF series) is a high-performance
F-Frame AC servo driver designed for high-output applications up to 5000W (5.0 kW) within the MINAS A6 family. As a "Multifunction Type" driver, it offers advanced control capabilities and fast processing for demanding industrial environments. [

The primary function of the Panasonic MFDLTB3SF is to act as the "multipurpose brain" and power station for 5.0 kW A6 servo motors. It translates complex commands from a controller into high-current electricity to move massive industrial loads with surgical precision.
1. Universal Control (Multifunction)
Unlike basic drivers, the A6SF series can handle any type of motion command:
- Position Control: For precise "point-to-point" moves (Robotic arms, CNC tables).
- Velocity Control: For maintaining a perfectly steady speed (Spindles, conveyors).
- Torque Control: For maintaining a specific "pushing force" (Tensioning, winding, pressing).
- Full-Closed Loop: It can read an external scale (like a linear ruler) to correct for mechanical errors in the machine itself.
2. High-Speed "Real-Time" Tuning
This driver functions as an active stabilizer for the heavy mass moved by 5kW motors:
- 3.2 kHz Response: It checks the motor's position and adjusts power 3,200 times every second. This eliminates "lag" and ensures the machine reacts instantly.
- Real-Time Auto-Tuning: It automatically senses the weight of the load (e.g., if a crane picks up a part) and instantly adjusts its internal math to keep the movement smooth without manual setup.
3. Integrated Machine Safety (STO)
The driver serves as a critical safety component via the Safe Torque Off (STO) function:
- It provides a hardware-level way to cut power to the motor instantly if a safety gate is opened or an E-Stop is pressed. This ensures the motor cannot move while a human is in the danger zone, even if the software fails.
4. Vibration & Resonance Suppression
At 5.0 kW, mechanical vibration can be loud and destructive. The MFDLTB3SF acts 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 for faster cycle times without noise or mechanical wear.
5. Communication & Feedback Bridge
- Interface: It connects to almost any system via Analog signals, Pulse trains, or digital data via Modbus (RS485/RS232).
- Data Hub: It translates the 8.38 million pulses per turn from the motors encoder into digital information that the main PLC can use to track the machine's exact location.
