RoboteQ AX3500 manual Technical Features, Ordering Information

Technical Features

Microcomputer-based Digital Design

•Multiple operating modes

•Fully programmable using either built-in switches and 7 segment LED display or through connection to a PC

•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

•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 calibration

•Selectable deadband width

•Selectable exponentiation factors for each joystick

•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

•8 RC pulses outputs for connection to additional Roboteq slave controllers or RC servos

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

•200mA at 12V or 100mA at 24V idle cur- rent consumption

•Power Control wire 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 2.5 mOhm ON resistance MOSFETs

•Four quadrant operation. Supports regen- eration

•12 to 40 V operation

•Standard Fast-on connectors for power supply and motors

•16 kHz Pulse Width Modulation (PWM) output

•Aluminum heat sink. Optional conduction cooling plate

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)

•Large and bright run/failure diagnostics on 7 segment LED display

•Programmable motors acceleration

•Built-in controller overheat sensors

•“Dead-man” switch input

•Emergency Stop input signal and button

Compact Design

•All-in-one, single board design
