Image
Analyzer
Read and write variables dynamically while driving a motor.
- Dynamically display waveform while driving a motor.
- Specify trigger and each display settings with the waveform display.
- The commander function allows creation and transmission of sequences for changing variables of your choice.
- The user button function lets you change a user-defined group of variables with a single click.
- Operating procedure of each RMW function is displayed while you work.
- Adjusted variables can be output as macro definitions to header files.
- Display variable usage information by reading a CSV file.
Image
Tuner
- Automatically measures motor-specific parameters (resistance, inductance, induced voltage constant, inertia).
- Automatically adjust the proportional integral (PI) control gain of current/speed/position.
- Automatically adjust the expected gain for sensorless vector control.
- Manual tuning to finely adjust each PI control.
- Output results in pdf and motor-driver header files.

Tuner for RL78 [New in RMW 3.2]
- Automatically measure motor-specific parameters (resistance, inductance, BEMF constant, inertia, friction coefficient, parameters for initial position detection).
- Automatically design parameters for sensorless vector control and fixed point arithmetic.
- Manually adjust each parameter.
- Easily perform drive tests such as startup, steady-state drive, and step response of speed and current.

Image
Servo
The following GUI for Servo control has been implemented. The Servo Adjustment screen is displayed when you select [Servo] from Select Tool in the Main Window.
- Motor axis connected load inertia estimation function
- Servo setting configuration function covering position control type, fixed frequencies, etc.
- Function for configuring the origin return method, return speed, etc.

Image
DLL
Variable read and write functions executed by the RMW (GUI) are provided in a DLL, making it possible to create tools using Excel VBA or as .NET applications.

Built-in Communication Library
The download package contains both a standard communication library and a built-in communication library. Embedding the built-in communication library in the motor control program allows you to perform simple debugging using a USB-serial conversion board instead of a communication board compatible with Renesas Motor Workbench. Supported MCUs are the RA8T1, RA6T2, RA6T3, and RA4T1 (with support for additional MCUs planned for future release).
The number of points of waveform display data that can be displayed using the Analyzer module is limited, but other functions can be used in the same way as when using a communication board.
