Question

Motor control with resolver

Good afternoon,

I am working with the STSW-TTM005 example for a resolver-equipped motor and encountered an issue:
Link: STSW-TTM005 | Product - STMicroelectronics

The motor does not rotate, but instead oscillates between windings.
In sensorless mode, the motor rotates correctly.
During debugging, the resolver angle appears correct.
I tried changing that setting:
#define RESOLVER_ANGLE_OFFSET_DEGREE 185.0f // Angular offset in electrical degrees between the resolver and the rotor's magnetic flux, but it didn't work

Could you please clarify which resolver-equipped motor was used to validate this solution? My setup is as follows:

I would appreciate guidance on whether my configuration is compatible and any recommended adjustments.

Thank you for your support.
