Features

Renesas Motor Workbench is a development support tool for debugging, analyzing, and tuning motor control programs. Features include:

  • Easy GUI
    • Intuitive operation makes it easy to control motor speed and position.
  • Analyzer
    • Dynamic reading/writing of variables and waveform display while operating the motor.
  • Tuner
    • Automatic identification of motor parameters and control gains required for vector control. It's easy to fine-tune and the results are instantly visible.
  • Servo
    • Implements an adjustment function for the motor’s embedded position control system. (Supports adjustment of position control parameters, inertia estimation, origin return operation, and point-to-point control.)
  • DLL
    • Functions needed for debugging are provided as APIs, allowing connection to a GUI developed to the user’s specifications.
  • Built-in communication library
    • In addition to the standard library, a communication library for simple debugging using a commercially available serial-USB conversion cable or the like is provided.

Function Details

Easy GUI

Implements a GUI that allows more intuitive operation of the motor.

  • Ability to set instruction values by manipulating sliders.
  • Ability to configure instruction value profiles.
  • Display of rotation speed, current values, etc., on meters.
  • Switches for function switching.
  • Waveform display of changes in values of variables.
  • Ability to display a variety of parameters.

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 variableswith a single click.
  • [New in RMW 3.1] Operating procedure of each RMW function is displayed while you work.
  • [New in RMW 3.1] Adjusted variables can be output as macro definitions to header files.
  • [New in RMW 3.1] Display variable usage information by reading a CSV file.

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.

Servo [New in RMW 3.1]

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.
  • Function for point-to-point (PTP) single-axis operation.

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 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.
