AX100000: 150A DC Motor Controller

The motor controller can be operated as either a self-contained control system, driving the motor directly from the onboard inputs, or it can be integrated into a CAN J1939 network of controllers. It has two analog (voltage or current), two timer (frequency, RPM or PWM inputs) and 4 active high digital inputs that can be used to drive the motor or extra outputs. In addition to the powerful motor drive, the motor controller has two sourcing outputs to drive two hydraulic proportional coils up to 2A each, and two high-side digital outputs for up to 3A loads. This allows the motor controller to be a fully integrated control platform for small machines using a combination of hydraulic actuators and a motor drive system. It uses full isolation to separate the inputs and the processor section of the controller from the motor power and output. The motor controller has a number of built-in protection features that can shutoff the motor in adverse condition. These features include hardware shutoffs to protect the circuits from being damaged as well as software shutdown features that can be enabled in safety critical systems.
