Overview Block DiagramThe PW-8256XNX series is a family of completely self-contained and versatile high performance motor controllers designed to control a wide variety of brushless DC motors and loads. These modules are fully configurable through a Graphical User Interface (GUI) operating on a Windows® platform, and provide torque (current) and speed (voltage) control using sensorless algorithms or Hall Effect feedback.

The PW-8256XNX operates from an analog or digital input command to control motor speed or torque. The motor current and back EMF may be internally sensed and processed to control speed and torque using field oriented control for sinusoidal commutation. Alternatively, the controller can provide trapezoidal commutation based on Hall sensor feedback.

These 3-phase controllers provide true four-quadrant control through zero current. The Pulse Width Modulation (PWM) switching frequency is also programmable, making them suitable for operation with a wide variety of BLDC motors and operating requirements. The PW-8256XNX devices can accept single-ended or differential analog command signals, or may be controlled digitally through their CANbus or RS-422/485 interfaces. All control loops’ tuning parameters are user programmable to optimize system performance based on motor and load characteristics. The GUI can also be used to run the motor/system, thereby saving setup, test and evaluation time.

The PW-8256XNX series is available mounted to an evaluation card for quick lab testing.
