3.6.3 mcIpdI_InitialPositionDetect
C
/* Perform initial position detection */
void mcIpdI_InitialPositionDetect(tmcIpd_ModuleData_s * const pModule);
Summary
This function performs initial position detection.
Description
This function performs the Initial Position Detection (IPD) process to determine the initial rotor position of the PMSM motor before normal operation. It achieves this by exciting the motor with a specified PWM signal, reads the resulting phase currents, and calculating the rotor position based on the input data.
Precondition
The IPD module must be initialized and enabled.
Parameters
| Param | Description |
|---|---|
| pParameters | A pointer to the IPD module parameter structure |
Returns
None
Example
// Define the IPD module data structure
tmcIpd_ModuleData_s ipdParameters;
/* Perform initial position detection */
mcIpdI_InitialPositionDetect(&ipdParameters);
