About MBDLN25SG - A6SG Panasonic A6 400W Driver

MBDLN25SG (MINAS A6SG 400W Servo Drive)

The MBDLN25SG is a Panasonic MINAS A6SG series servo amplifier (driver) used to control 400W class servo motors.

Basic Specifications

• Model: MBDLN25SG
• Series: MINAS A6SG
• Compatible Motor Power: 50 W 5 kW (supports 400W motors easily)
• Supply Voltage: 200 V AC (single/3-phase)
• Control Mode: Position control (pulse input / Modbus RS485/RS232)
• Bandwidth (response): 3.2 kHz (high-speed servo response)

Communication & Control

• Pulse input (STEP/DIR type control)
• RS232 communication
• RS485 / Modbus RTU
• Up to 31-axis multi-drop communication
• USB parameter setup via PANATERM software

Functional Features

• Closed-loop servo control (position feedback from encoder)
• 23-bit absolute encoder support (very high precision)
• Auto tuning & vibration suppression
• Internal position table (block operation up to 256 steps)
• Dynamic braking support
• No safety STO function (SG = basic variant)

Physical Size (Driver)

• Height: 150 mm 5.91 in
• Width: 55 mm 2.17 in
• Depth: 130 mm 5.12 in
• Weight: ~1.0 kg 2.2 lb

Key Role (Function)

This device is the control brain + power amplifier of the servo system:

• Receives motion commands (PLC/CNC)
• Processes encoder feedback from motor
• Controls motor current precisely
• Ensures exact position, speed, and torque control

Simple Explanation

• Motor = muscle
• Driver (MBDLN25SG) = brain + power controller
• Encoder = eyes (position feedback)

Without this driver, the 400W Panasonic A6 servo motor cannot operate correctly.

One-line summary

MBDLN25SG is a compact 400W Panasonic A6SG servo driver that provides high-speed (3.2 kHz), closed-loop position control for industrial automation systems.
