In the field of motor control, it is a very effective function because it can’t check the variables inside the MCU by breaking (stopping) the program like other applications. This feature is particularly important in motor control applications. This avoids the risk of damaging the inverter board with over current that might result if the CPU were to be stopped under certain PWM output conditions. One important advantage of the analyzer is that it allows the user to read and write MCU internal variables, and to view real-time waveform displays, with no need to stop the CPU or shut down the motor.

The Renesas Motor Workbench (RMW) implements both “analyzer” and “tuner”.

Let’s begin with 120-degree conducting control.įigure 2: Renesas Motor Workbench: Initial Screen In this session, we will try both 120-degree conducting control with Hall sensors, and sensorless vector control. Other available CPU cards, with different MCUs, can be used in its place, allowing users to try multiple MCUs, and perhaps to choose from among them.Ī variety of control software is available for use with Motor RSSK, providing support for vector control (Field oriented control), 120-degree conducting control, and more. The kit presented here comes with an RX23T motor-control MCU, mounted on a CPU card that attaches to the inverter board. Users can freely download the related control software and development support tools from the Renesas website-making it easy for just about anyone to get some hands-on experience with various types of motor control method. The Motor RSSK provides all of the essentials for implementing motor control, and is effectively an out-of-the-box solution.
