EVSPIN32G4 – Motor 2 not rotating in Sensorless FOC (works in MC Workbench 6.3.2 but not in 6.4.1)

[Chandana_Arava]

I’m using the EVSPIN32G4 dual motor control board with MotorControl Workbench 6.4.1 in Sensorless FOC mode.

Both motors have identical configurations, but Motor 2 doesn’t rotate when using Workbench 6.4.1.
The same setup works perfectly in Workbench 6.3.2, where both motors run normally.

Hardware and wiring are fine — this seems to be a software or code-generation issue in Workbench 6.4.1 for dual-motor projects.

Can you please confirm if this is a known issue or regression in version 6.4.1, and suggest a fix or workaround?

Setup Summary:

• Board: EVSPIN32G4

• Mode: Sensorless FOC, Dual Motor

• MC Workbench: 6.4.1 (issue), 6.3.2 (working)

• IDE: STM32CubeIDE 1.19.0

Hello @Chandana_Arava,

Is an error reported?
From my side, both motors operate with the same configuration in STO-PLL.
Can you share your .stwb6 file?
