MSA70D Digital Single Axis 70A Open Frame Motor Controller

This robust digital low voltage single axis controller is designed to provide torque, velocity and position loop closure. It has a CAN Bus command interface and also can receive an analog command signal. An open frame design with cold plate mount is used to reduce the overall cost and to allow this controller to be easily incorporated into existing vehicle electronics. The advanced space vector algorithms provide optimum performance for new or existing motors to provide superior power densities. There is also a control power input option that replaces the +/-15V, and 5V supplies with 28V. Additionally, there are a wide range of end user programmable software features, as listed below.
