MD49 - Dual 24 Volt 5 Amp H Bridge Motor Driver

Motor driver for 2 EMG49-Motors

Devantech

Overview

The MD49 is a robust serial dual motor driver, designed for use with our EMG49 motors. Main features are:

• Reads motors encoders and provides counts for determining distance traveled and direction of rotation.
• Drives two motors with independent or combined control.
• Motor current is readable.
• Only 24v is required to power the module.
• Steering feature, motors can be commanded to turn by sent value.
• Variable acceleration and power regulation also included
• Protection against short circuit output, over current and incorrect voltage. Also included is an error LED and error byte for diagnosis of faults.

Connections

Automatic Speed regulation

By using feedback from the encoders the MD49 is able to dynamically increase power as required. If the required speed is not being achieved, the MD49 will increase power to the motors until it reaches the desired rate or the motors reach there maximum output. Speed regulation can be turned off with the use of the REGULATOR DISABLE command.

Automatic Motor Timeout

The MD49 will automatically stop the motors if there is no serial communications within 2 seconds. This is to prevent your robot running wild if the controller fails. The feature can be turned off with the DISABLE TIMEOUT command.

Controlling the MD49

The MD49 is designed to operate with a TTL level serial bus (5v levels) at either 9600 or 38400 baud depending on the jumper selection and accepts either one or two stop bits. A jumper is supplied to make the default shipped baud rate 38400. Do not connect the MD49 to RS232 directly, if you wish to connect to RS232 it must be with the aid of a voltage level converter such as a ST232 or serial interface such as S13 which is available here: www.robot-electronics.co.uk/acatalog/Serial_Interface.html
