TQ10X Controller/Drive—Description & Block Diagram
The TQ10X Servo Controller/Drive is a servo drive designed to run three phase
brushless DC servo motors equipped with Hall effect sensors, using trapazoidal
commutation. It can also operate brushed DC servo motors.
The block diagram for a typical system is shown below.

Block Diagram – TQ10X Controller/Drive
Inside the drive, there are two circuit boards—a position controller board, and a
torque drive board. The position controller receives information about actual
position from an encoder.-
Inputs, outputs, and RS-232C communications also enter the position controller
board, where they interface with a microprocessor. The microprocessor can enable
or disable the torque board. It also generates a position command. The position
command is compared with actual position at a summing node; the result passes
through a digital-to-analog converter, where it becomes an analog voltage signal.
