Release Notes for ST Motor Pilot 1.1.12

Copyright © 2023 STMicroelectronics

The ST Motor Pilot is a control and monitoring PC tool. It is built on a brand new communication protocol that allows for faster and more reliable communication while consuming less MIPS from the MCU. With this protocol, internal Motor Control signals can be monitored in real time with no or controlled subsampling.

Main features :

• Control and reporting of motor control firmware parameters
• Customizable UI
• Real time data plotting (oscilloscope like feature)

It embeds also another tool, the Motor Profiler software tool that provides the following features:

• A PC software application as a qml file to measure electromechanical parameters of PMSM motors

• Embedded One Touch Tuning algorithm: algorithm that uses a single parameter to set up the speed controller according to the type of load Together with the ST Motor Profiler software tool, it can be enabled to achieve the setup and run unknown motor from scratch

• Measured motor parameters can be configured in the MC application, thanks to ST Motor Control Workbench.

• Pole pairs detection

• Profiling motors with ST Motor Profiler

  When using the Motor Profiler the user must make sure that the motor is fully stopped (spinning at 0 RPM) before starting it again whatever the method (by clicking on Play, Start Profile, ...).

  After a fault occurred, or before starting the motor, the low side switches are activated in order to detect if the motor is spinning. Indeed, if the motor is spinning at that time, it may decelerate abruptly which can be dangerous. Great care must be taken to tightly fasten the motor so that it does not become dangerous when accelerating or decelerating brutally.

Known Limitations

• Only single drive applications are currently supported

• The Datalog service cannot stream Medium frequency task data yet (such as the Motor State or the measured speed for instance). This is not implemented in the current firmware.

• Registers cannot be modified from the Registers view.

• For the motor profiler, this power board is not yet supported :

  • Control boards :

    • STM32G081B-EVAL

  • Power boards :

    • EVALSTDRIVE101

Update History

v1.1.12 / 15-May-2023

Main Changes

This version of the Motor Pilot fixes bugs from Pilot previous version.

Features added to the Motor Pilot

• Fix Profiler issue with "Check ST-Link Connection" never connects
• Profiler UI must configure Voltage thresholds before profiling

v1.1.5 / 14-Feb-2023

Main Changes

This version of the Motor Pilot fixes bugs from Pilot previous version.

Features added to the Motor Pilot

• Profiler binary Overvoltage value aligned with board specification

• Add Y cursor

• Fix autoscale issue

• Fix issue when switching between UI with high frequency plot active

• Fix trigger level issue

• Fix easy reading scaling

• Added new board support for Motor profiler feature:

  • Control boards :

    • STM32G474E-EVAL

v1.1.3 / 16-Dec-2022

Main Changes

This version of the Motor Pilot provides a new application UI that allows for profiling a unknown motor. This UI is very similar to the one provided with the retired ST Motor Profiler tool. In addition to it, the application adds the capability to detect the configuration of Hall sensors if the motor under profiling has them and it can also automatically detect the configuration of the hardware it is connected to. Version 1.1.3 of the Motor Pilot embbeds the Motor Profiler tool and fixes bugs from Pilot previous version.

Features added to the Motor Pilot

• Integrates the Motor Profiler tool

• Added feature to read/write/execute file from qml : user can now access to any data on his computer from qml file of the Pilot

• New plot snapshot feature : like oscilloscope instrument with ability to make a snapshot of a plot and then compare it to another plot

• A new plot sum function : like oscilloscope instrument with ability to sum up to 3 plots

• Added trigger function to high frequency plot

• Change Rs estimation display background if value is too much different from Rs Rated

• Hall sensors configuration detection for motor profiling

• Add support of touchscreen device

• Added new board support for Motor profiler feature:

  • Control boards :

    • B-G431B-ESC1
    • NUCLEO-F302R8
    • NUCLEO-F303RE
    • NUCLEO-F401RE
    • NUCLEO-F446RE

    • NUCLEO-G431RB
    • NUCLEO-L452RE
    • NUCLEO-L476RG
    • STM32303E-EVAL

  • Power boards :

    • X-NUCLEO-IHM07M1
    • X-NUCLEO-IHM08M1
    • X-NUCLEO-IHM16M1
    • STEVAL-IPM05F
    • STEVAL-IPM10B

v1.0.0/ 30-Mar-2022

Main Changes

Version 1.0.0 of the Motor Pilot provides new features and fixes bugs from Pilot version provided with MCSDK 5.Y.4 previous version.

Features added to the Motor Pilot

• Motor power reported in floating point instead of U16
• Renamed register FLAGS into FAULT_FLAGS
• Added support for switching from open loop to closed loop at run time
• Disabled the polling of registers related to non available features
• The name of the boards used in the embedded application is now displayed
• Improved support of Six-Step
• Improved Torque reference reporting in the Advanced Configuration panel
• Fixed an issue with the usage of the slider used to set the speed reference.
• Nominal current is now reported into S16 instead of U16.
