Products Description
Toshiba TOEI VLASX-100P3-HXM Velconic X Servo Drive Unit

Module Feature
VLASX-100P3-HXM belongs to Toshiba TOEI classic Velconic X series servo amplifier. It adopts V/C engine hardware control architecture, realizes ultra-fast current and speed loop sampling. The suffix HXM stands for resolver feedback type, supporting resolver motor without optical encoder. It supports position, speed and torque control modes, pulse-direction command, analog reference and rich programmable I/O. Built-in multi-notch resonance suppression, auto-tune function, separate control power circuit. Comprehensive protection includes overcurrent, overvoltage, undervoltage, resolver signal loss, overload and heatsink overtemperature. Widely stocked as spare for heavy CNC machine, injection molding, material handling and semiconductor process equipment.
Working principle
Three-phase AC input is rectified into DC bus, IGBT inverter outputs PWM adjustable voltage and frequency to servo motor. Hardware ASIC executes flux and torque decoupling vector algorithm. Resolver signal is decoded to get rotor angle and speed for closed-loop regulation. Internal fault monitoring circuit continuously detects power stage, feedback signal and temperature, and triggers safe stop when abnormal condition occurs. Parameter set and fault history can be uploaded by dedicated software.
Onboard componentsRectifier assembly, IGBT power module, Velconic V/C control ASIC, resolver excitation & decoding circuit, analog/pulse command interface, cooling fan, status display panel and metal reinforced housing.
LED indicatorsFront LEDs indicate power, servo ready, enable, alarm and fault status; numeric display shows alarm code.
Hardware self‑diagnosisDrive monitors DC bus voltage, output current, resolver signal integrity, internal temperature and I/O status. Speed loop gain, electronic gear and filter parameters can be adjusted locally or via software.
Programming softwareVelWen (Toshiba Velconic configuration tool), used for parameter editing, motor auto-tune, waveform capture and fault log reading.
