MSA70D Digital Single Axis 70A Open Frame Motor Controller

MSA70D Digital Single Axis 70A open Frame Motor Controller

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