Rexa SMB9275-1B-1-6671 Digital Brushless Servo Amplifier

Rexa SMB9275-1B-1-6671 is an Omega Series digital PWM brushless servo amplifier designed to drive three-phase brushless servo motors in precision motion systems. As a surface-mount Omega drive, it delivers DSP-based control of the motor and operates in Velocity Mode, where the amplifier uses a tachometer signal to close the velocity loop under software running on the Rexa CPU. The analog velocity command is applied via a +/-3 VDC input that sets acceleration, speed, and deceleration, enabling tight velocity regulation and smooth startup. The module provides discrete control and diagnostic signals for safe operation, including enable and fault indicators associated with the commanded motor channel. With Rexa's Omega architecture, SMB9275-1B-1-6671 supports integration into automated systems where stable velocity tracking and responsive torque are required, such as robotics, CNC tooling, and automated packaging lines. The combination of digital PWM control, DSP processing, and feedback capability makes it suitable for applications demanding repeatable, high-precision motion control with a Rexa CPU coordinating the velocity loop.
