Lecture registre HALL_EL_ANGLE ou HALL_SPEED

[Christophe65]

Bonjour,

    J'ai configurer le contrôle moteur avec un capteur effet hall en auxiliaire.

le moteur tourne mais les valeur des registre ne change pas. elle prennent une valeur différente a chaque démarrage mais ensuite ne change jamais.

Comment vérifier ces paramétrages ?

Pourquoi les valeur de registre ne change pas ?

J'ai vérifier tout le câblage, il est bon.

J'utilise une nucléo-G431RB et X-NUCLEO-IHM08M1

Merci pour votre aide

Hello @Christophe65 and welcome to ST Community,

As mentioned in st-community terms and conditions: "The language of the Community is English".
What registers are you talking about? And what tool do you use to visualize your registers (debugger, motor pilot, ...)?

Hello,

I understand, and I will do my best to speak English on this forum.

The registers I want to read are those related to the Hall effect sensor with the ST Motor Pilot V1.2.9 - MC_FOC_SDK:

I am using the Motor Pilot to study motor control and plan to use the SDK to control a brushless motor with a Hall effect sensor to operate an industrial door.

The value of this register changes every time the motor starts and then remains constant.

Thank you for your help.

Hello @Christophe65,

As Hall Sensor is set Auxiliary, motor will spin even if Hall Sensor is not functional.
Could you please check with a scope HALL sensor signals? 
On the other hand, you can also display these parameters with high-speed plotting as described here.

Hello,

My problem is solved. After analyzing the signals, I realized that I had forgotten to add Pull-Up resistors on the outputs of the HALL sensor."

Thank you.
