Motor current waveforms custom board + MCSDK

STuser2
Associate II

I am trying to run a custom board using MCSDK micro STM32G4 series,  using cube monitor took the waveforms i have queries on the waveforms pls help me if they are correct or abnormal

a. Phase currents are not correct, i am not sure why are not overlapping, i mean 120 phase shifted.

b.

CntPhA, CntPhB, CntPhC look to be ok for me but the problem i am observing is the duty cycle is going upto 5000 i have set the system at 15Khz hence the max count is 5666, does it mean it already got saturated, i am running the motor at 26V the motor is run at 60V in the vehicle.

c. Vq also going upto 25000.

d. 

/*** Noise parameters ***/

#define TNOISE_NS 500

#define TRISE_NS 200

i have never measured the above values on the scope including the Dead Time for my system,

is it mandatory to measure the above values and input to the system.
