Model Description

AX1500 Dual Channel DC Motor controller up to 30 SmartAmps per channel

Microcomputer-based Digital Design

• Multiple operating modes

• Fully configurable using a connection to a

• Non-volatile storage of user configurable

settings. No jumpers needed

• Simple operation

• Software upgradable with new features

Multiple Command Modes

• Serial port (RS-232) input

• Radio-Control Pulse-Width input

• 0-5V Analog Voltage input

Multiple Motor Control modes

• Independent channel operation

• Mixed control (sum and difference) for

tank-like steering

• Open Loop or Closed Loop Speed mode

• Position control mode for building high

power position servos

• Modes can be set independently for each

channel

Optical Encoder Inputs (option)

• Two Quadrature Optical Encoders inputs

• 250kHz max. frequency per channel

• 32-bit up-down counters

• Inputs may be shared with four optional

limit switches

Automatic Command Corrections

• Joystick min, max and center values

• Selectable deadband width

• Selectable exponentiation factors for each

command inputs

• 3rd R/C channel input for accessory output

activation

Special Function Inputs/Outputs

• 2 Analog inputs. Used as

• Tachometer inputs for closed loop

speed control

• Potentiometer input for position (servo

mode)

• External temperature sensor inputs

• User defined purpose (RS232 mode

only)

• One Switch input configurable as

• Emergency stop command

• Reversing commands when running

vehicle inverted

• Up to 2 general purpose outputs for acces-

sories or weapon

• One 24V, 2A output

• One low-level digital output

• Up to 2 digital input signals

Built-in Sensors

• Voltage sensor for monitoring the main 12

to 40V battery

• Voltage monitoring of internal 12V

• Temperature sensors near each Power

Transistor bridge

Advanced Data Logging Capabilities

• 12 internal parameters, including battery

voltage, captured R/C command, tempera-

ture and Amps accessible via RS232 port

• Data may be logged in a PC or microcom-

puter

• Data Logging Software supplied for PC

Low Power Consumption

• On board DC/DC converter for single 12 to

40V battery system operation

• Optional 12V backup power input for pow-

ering safely the controller if the main

motor batteries are discharged

• 100mA at 12V or 50mA at 24V idle current

consumption

• Power Control input for turning On or Off

the controller from external microcom-

puter or switch

• No consumption by output stage when

motors stopped

• Regulated 5V output for powering R/C

radio. Eliminates the need for separate R/C

battery.

High Efficiency Motor Power Outputs

• Two independent power output stages

• Dual H bridge for full forward/reverse oper-

ation

• Ultra-efficient 5 mOhm ON resistance

MOSFETs

• Four quadrant operation. Supports regen-

eration

• 12 to 40 V operation

• User programmable current limit up to 30A

• Standard Fast-on connectors for power

supply and motors

• 16 kHz Pulse Width Modulation (PWM)

output

Advanced Safety Features

• Safe power on mode

• Optical isolation on R/C control inputs

• Automatic Power stage off in case of elec-

trically or software induced program failure

• Overvoltage and Undervoltage protection

• Watchdog for automatic motor shutdown

in case of command loss (R/C and RS232

modes)

• Run/failure diagnostics on visible LEDs

• Programmable motors acceleration

• Built-in controller overheat sensors

• “Dead-man” switch input

• Emergency Stop input signal and button

Compact Design

• All-in-one board-level design.

• Efficient heat sinking. Operates without a

fan in most applications.

• 4.25” (108mm) L, 4.25” W (108mm), 1”

(25mm) H

• -20o to +70o C operating environment

• 3oz (85g)
