Hi All, I'm using NUCLEO-F401RE + X-NUCLEO-IHM02A1 + NEMA17 stepper motor. Motor stalls above 6rps (1200steps/sec). Can someone share MotorParameterData_t for NEMA17 stepper motor, 103H5210-5240 (SANYO DENKI - SANMOTION 103H5210-5240 Stepper Motor)?
My present MotorParameterData_t attached (NEMA17_stepper_param.txt)
Also, Any tools available for calculation of MotorParameterData_t?
Solved! Go to Solution.

Dear @S.Kamath
You can find some guidelines about the configuration of the L6470 in the AN4144 Voltage mode control operation and parameter optimization
Calculation requires to know:
An useful tool for the configuration "BEMF compensation tool" embedded into the SPINFamily. It calculates all the parameters automatically starting from the input above.

Thanks Laurent,
I have seen above mentioned link.
const MotorParameterData_t MotorParameterInitData[EXPBRD_MOUNTED_NR_MAX][L6470DAISYCHAINSIZE] = {
{
{9.0, 400, 1.7, 3.06, 240.0, 400.0, 400.0, 320.0, 0.0, 602.7, 3.06, 3.06,\

Dear S.KAMATH
My team is in charge of Motor Control SDK which does not currently cover stepper motors, but I have forwarded your message internaly in order to check if we can answer you.
Best regards.

Thanks Laurent..!
We're running pump at 1/128 micro stepping. We have observed improved performance at 1/16 micro stepping
Not tried half-step or full-step as we're looking higher precision
