AX500 - Low Power, 2 x 15A Brushed DC Motor Controller

Manuals & Software

Product Description

Roboteq’s AX500 controller is designed to convert commands received from a R/C radio, Analog Joystick, wireless modem, or microcomputer into high voltage and high current output for driving one or two DC motors.

The controller's two channels can either be operated independently or mixed to set the direction and rotation of a vehicle by coordinating the motion on each side of the vehicle. The motors may be operated in open or closed loop speed mode. Using low-cost position sensors, they may also be set to operate as heavy-duty position servos.

The controller can be reprogrammed in the field with the latest features by downloading new operating software from Roboteq.
