Hello,
We are currently performing tests on stepper motor driver boards.
We are using a NUCLEO-F401RE board, which works correctly with the X-NUCLEO-IHM14A1: the motor rotates normally using the interface provided by STSPIN Studio 2.0.
However, while keeping the same NUCLEO-F401RE board and replacing the X-NUCLEO-IHM14A1 with an evaluation board based on the STSPIN948, we are unable to make the motor rotate. The motor produces a whistling and mechanical noise, but no rotation occurs.
The following configurations have been applied
- J5 = 1
- J6 = 1
- J7 = 0
In addition:
- Modifications to REFA and REFB have no effect on the motor behavior.
- Changing parameters in STSPIN Studio 2.0 does not seem to affect the board.
- Using an oscilloscope, we verified that the phase shift between signals A and B is correctly set to 90°.
Could you please help us identify the cause of this issue or suggest a troubleshooting procedure?
Thank you in advance for your support and assistance.
