New Original Mitsubishi BC337U025 MR-J2S-100B-QE 1kW SSCNET AC Servo Drive
1. Product Overview
MR-J2S-100B-QE (BC337U025) is an original Mitsubishi Electric AC servo amplifier belonging to the MELSERVO-J2-Super series. This model adopts SSCNET optical fiber high-speed serial bus interface, with rated continuous output power of 1.0 kW under 200V class power supply. It works cooperatively with Mitsubishi HC-KFS, HC-SFS series servo motors equipped with serial encoders.
As a network-type servo drive, all motion commands are transmitted via SSCNET bus from Mitsubishi Q-series motion controllers such as Q172CPU and Q173CPU. It supports high-precision position, speed and torque closed-loop control. Widely used in CNC equipment, packaging machinery, automated assembly lines, textile machines and multi-axis synchronization automation systems. The suffix QE stands for special specification variant, while BC337U025 serves as the internal production part number. This unit supports absolute encoder positioning when matched with backup battery, eliminating repeated homing after power cycle. It is designed for cabinet DIN rail installation and features strong anti-electromagnetic interference performance for industrial workshop environments.
2. Main Functions
- SSCNET Optical Fiber Bus Motion Control Receives position, speed and torque commands via original SSCNET serial communication bus. The shortest communication cycle reaches 0.888 ms, realizing multi-axis synchronous interpolation and coordinated motion control. Optical transmission effectively suppresses electromagnetic noise interference.
- High Response Closed-Loop Servo Control Adopts sinusoidal PWM control algorithm; speed loop frequency response reaches 550 Hz, delivering fast dynamic response and stable low-speed operation. Supports three control modes: position control, speed control and torque control.
- Absolute Position Detection Function External backup battery can be installed to maintain absolute encoder position data. Equipment restarts without homing operation, improving machine operation efficiency.
- Built-in Dynamic Brake Circuit Internal dynamic brake enables rapid motor stopping during emergency conditions. External regenerative resistors can be connected to consume regenerative energy generated during frequent deceleration.
- Comprehensive Multi-Level Protection Mechanism Provides complete fault protection including overcurrent, overvoltage, undervoltage, overload, motor overheat, encoder abnormality, overspeed and position excess error. Fault codes are displayed for rapid troubleshooting.
- Parameter Upload/Download & Monitoring Supports connection with MR Configurator software via RS-232C interface to realize parameter editing, running data real-time monitoring and fault record reading.
- Flexible Gain Adjustment Built-in automatic gain tuning function; supports segment switching gain according to load changes to balance positioning accuracy and system stability.
