Brushless DC drive BLAR-09070-MH

three-phasepermanent magnetModbus

Overview
The BLAR series is an industrial high-performance intelligent digital brushless DC (BLDC) drive family integrating positioning control and drive functions in one unit. The BLAR-09070-MH supports motor control up to 15 kW and is suited for speed and torque control of permanent-magnet BLDC motors with Hall or sensorless feedback. Interfaces include external control, RS232, RS485 (Modbus RTU), and optional CANopen; feedback options include digital Hall and incremental encoder.
