INSTASPINFOCMOTORWAREGUI: Implementing LAB21 of motorware on hvkit_rev1p1 kit

Hi,

            i am trying to tune the IPD_HFI parameters. Right now i am playing with the Course and Fine excitation magnitudes and wait times. I am getting the current waveform similar to sinusoidal with magnitude of 325.2 mA. But i am not able to get the waveform same as given in LAB21 of instaspin lab manual.  The parameters are as follows

#elif (USER_MOTOR == MY_PMSMMOTOR)

#define USER_MOTOR_TYPE MOTOR_Type_Pm

#define USER_MOTOR_NUM_POLE_PAIRS (4)

#define USER_MOTOR_Rr (NULL)

#define USER_MOTOR_Rs (1.5018753)

#define USER_MOTOR_Ls_d (0.0108114174)

#define USER_MOTOR_Ls_q (0.0108114174)

#define USER_MOTOR_RATED_FLUX (0.650064)

#define USER_MOTOR_MAGNETIZING_CURRENT (NULL)

#define USER_MOTOR_RES_EST_CURRENT (0.5)

#define USER_MOTOR_IND_EST_CURRENT (-0.5)

#define USER_MOTOR_MAX_CURRENT (0.5)

#define USER_MOTOR_FLUX_EST_FREQ_Hz (20.0)

#define USER_MOTOR_FREQ_LOW (20.0) // Hz - suggested to set to 10% of rated motor frequency

#define USER_MOTOR_FREQ_HIGH (200.0) // Hz - suggested to set to 100% of rated motor frequency

#define USER_MOTOR_FREQ_MAX (240.0) // Hz - suggested to set to 120% of rated motor frequency

#define USER_MOTOR_VOLT_MIN (3.0) // Volt - suggested to set to ~20% of rated motor voltage

#define USER_MOTOR_VOLT_MAX (18.0) // Volt - suggested to set to 100% of rated motor voltage

#define IPD_HFI_EXC_FREQ_HZ             (750.0)       // excitation frequency, Hz

#define IPD_HFI_LP_SPD_FILT_HZ          (35.0)        // lowpass filter cutoff frequency, Hz

#define IPD_HFI_HP_IQ_FILT_HZ           (100.0)       // highpass filter cutoff frequency, Hz

#define IPD_HFI_KSPD                    (6.0)       // the speed gain value

#define IPD_HFI_EXC_MAG_COARSE_PU       (0.11)         // coarse IPD excitation magnitude, pu

#define IPD_HFI_EXC_MAG_FINE_PU         (0.09)         // fine IPD excitation magnitude, pu

#define IPD_HFI_EXC_TIME_COARSE_S       (0.6)         // coarse wait time, sec max 0.64

#define IPD_HFI_EXC_TIME_FINE_S         (0.5)         // fine wait time, sec max 0.4

#define AFSEL_FREQ_HIGH_PU              (_IQ(20.0 / USER_IQ_FULL_SCALE_FREQ_Hz))

#define AFSEL_FREQ_LOW_PU               (_IQ(10.0 / USER_IQ_FULL_SCALE_FREQ_Hz))

#define AFSEL_IQ_SLOPE_EST              (_IQ((float)(1.0/0.1/USER_ISR_FREQ_Hz)))

#define AFSEL_IQ_SLOPE_HFI              (_IQ((float)(1.0/10.0/USER_ISR_FREQ_Hz)))

#define AFSEL_IQ_SLOPE_THROTTLE_DWN     (_IQ((float)(1.0/0.05/USER_ISR_FREQ_Hz)))

#define AFSEL_MAX_IQ_REF_EST            (_IQ(0.4))

#define AFSEL_MAX_IQ_REF_HFI            (_IQ(0.4))

So what is going wrong??

How can i know whether i am going in right direction or not??  

Also is there document/link/video other than instaspin lab manual for IPD_HFI tuning??

Where to find gthrottle(Kspd tuning)??

Hi,

           please reply as soon as possible to this and previous questions also.

           What is the role of gThrottle_Result in LAB21 (IPD and HFI)??

Respected sir,

               I have replaced  the  HAL files of LAB20 and LAB21. The LAB 20 is working fine(able to run motor). So i think LAB 21 also should not have any problem. 

Also i have gone through the instaspin_lab guide for LAB21. 

I have calculated the excitation frequency and trying the cource and fine magnitudes. But rotor is not moving continuously.  

After setting  Flag_Run_Indetify the rotor is giving small jerk and stoping there with single tone sound.

So why this is happening??

My Ld and Lq are as follows

#define USER_MOTOR_Ls_d (0.0108114174)

#define USER_MOTOR_Ls_q (0.0108114174)

                  My Ld and Ls are same. Could  that be reason??

 Regards,

Digvijay
