Motor Controller

Overview

Congratulations! By selecting Roboteq’s AX2500/2850 you have empowered your- self with the industry’s most versatile and programmable DC Motor Controller for mobile robots. This manual will guide you step by step through its many possibili- ties.

Product Description

The AX2500/2850 is a highly configurable, microcomputer-based, dual-channel digi- tal speed or position controller with built-in high power drivers. The controller is designed to interface directly to high power DC motors in computer controlled or remote controlled mobile robotics and automated vehicle applications.

The AX2500/2850 controller can accept speed or position commands in a variety of ways: pulse-width based control from a standard Radio Control receiver, Analog Voltage commands, or RS-232 commands from a microcontroller or wireless modem.

The controller's two channels can be operated independently or can be combined to set the forward/reverse direction and steering of a vehicle by coordinating the motion on each side of the vehicle. In the speed control mode, the AX2500/2850 can operate in open loop or closed loop. In closed loop operation, actual speed mea- surements from tachometers or optical encoders are used to verify that the motor is rotating at the desired speed and direction and to adjust the power to the motors accordingly.

The AX2500/2850 can also be configured to operate as a precision, high torque servo controller. When connected to a potentiometer coupled to the motor assem- bly, the controller will command the motor to rotate up to a desired angular position. Depending on the DC motor's power and gear ratio, the AX2500/2850 can be used to move or rotate steering columns or other physical objects with very high torque.

The AX2500/2850 is fitted with many safety features ensuring a secure power-on start, automatic stop in case of command loss, over current protection on both channels, and overheat protection.
