MDC2250 Motor Controller Datasheet 1

MDC2250

2x60A

High Performance

Dual Channel

Forward/Reverse

Brushed DC Motor

Controller with USB

and Encoder Inputs

Roboteq’s MDC2250 controller is designed to convert com-

mands received from an RC radio, Analog Joystick, wireless

modem, PC (via RS232 or USB) or microcomputer into high

voltage and high current output for driving one or two DC

motors. Designed for maximal ease-of-use, it is delivered with

all necessary cables and hardware, and is ready to use in min-

utes.

The controller features a high-performance 32-bit microcom-

puter and quadrature encoder inputs to perform advanced

motion control algorithms in Open Loop or Close Loop (Speed

or Position) modes. The MDC2250 features several Analog,

Pulse and Digital I/Os which can be remapped as command or

feedback inputs, limit switches, or many other functions.

The controller’s two motor channels can either be operated

independently or mixed to set the direction and rotation of a

vehicle by coordinating the motion of each motor.

Numerous safety features are incorporated into the controller

to ensure reliable and safe operation. The controller's operation

can be extensively automated and customized using Basic Lan-

guage scripts. The controller can be reprogrammed in the field

with the latest features by downloading new operating soft-

ware from Roboteq.

motors at up to 60A output per channel

• Full forward & reverse control on each channel. Four quad-

rant operation. Supports regeneration

• Operates from a single 10V-50V power source

• Programmable current limit for each channel up to 2x60A

for protecting controller, motors, wiring and battery

• Up to 4 Analog Inputs for use as command and/or feed-

back

use as command and/or feedback

• Up to 6 Digital Inputs for use as Deadman Switch, Limit

Switch, Emergency stop or user inputs

• Dual Quadrature Encoder inputs with 32-bit counters

• 2 general purpose 24V, 1A output for brake release or

accessories

• Selectable min, max, center and deadband in Pulse and

Analog modes

• Selectable exponentiation factors for each command

inputs

• Trigger action if Analog, Pulse or Encoder capture are out-

side user selectable range (soft limit switches)

• Open loop or closed loop speed control operation

• Closed loop position control with analog or pulse/fre-

quency feedback

• Precise speed and position control when Encoder feed-

back is used

• PID control loop with separate gains for each channel
