ST SPIN MTPA slope and offset array

[RAlph.1]

Can anyone help me understand how these two arrays have been made

#define M1_ANGC                            {-116,-363,-611,-843,-1091,-1338,-1571,-1833}

#define OFST {0,17,51,99,167,252,348,474}

these arrays are used in MTPA calculation with y=mx+c equation.

These are the motor parameters for which the array has been calculated. Your assistance will be appreciated.

Hello @RAlph.1,

These tables provide a linear approximation of the curve described in the PMSM maximum torque per ampere (MTPA) control chapter of the User manual documentation, which is available through Workbench tool > About > Documentations > Documentation > User manual.
