6 step with PTOOLS1V1 firmware with STEVAL-PTOOL1V1 board

[ORaph.1]

I am working with the 6 step hall sensor firmware PTOOLS1V1. problem that i face is

This firmware is designed for 7 polepair and the motor with me is single polepair.i need to change the code to single polepair.

plz any one help me to change code to 1 polepair.

Hello @ORaph.1​,

you can change the Number of Motor Pole pairs in the STSW-PTOOL1V1 firmware opening the project file (refer to user manual UM2771 for more FW details).

The project has been implemented for:

• IAR Embedded Workbench v8.40.2 or later
• MDK-ARM v5.30.0 or later
• STM32CubeIDE v1.2.0 or later

In the “Inc�? folder you find the 6step_conf_hs_vm_spdlp.h file, here you can set the MOTOR_NUM_POLE_PAIRS parameter.

After the change, save, re-compile and load the new firmware in the device.

 

Let me know if this help you.

I have changed MOTOR_NUM_POLE_PAIRS to 1. But there is no change. Is there any other methods to overcome this .?

Hello @ORaph.1​,

could you share more details on your issue?

After the last change, there was no change compared to before? Or something happens?

Hi Cristiana @Cristiana SCARAMEL​ ,

when I change the pole pair to 1 the motor didn't move any step. So I do the following changes,

1). I put Motor_Device1.status = MC_ALIGNMENT in infinite loop so that motor will keep align continuously ,this started motor to rotate.

2). When the motor enters to MC_RUN the motor will go to MC_STOP immediately.

3). I just changed to 4 pair motor and run the code with 1 pole pair, by this code also 4 pair motor start to rotate with wrong speed calculation.

Hi @ORaph.1​ 

I suggest to check whether the Hall sensors decoding table (included in the same config file of MOTOR_NUM_POLE_PAIRS) is properly set according to your motor.

Let me know if this solve your problem
