TMDSHVMTRINSPIN: Motor is detected and runs with InstaSPIN_FOC_F2806xM GUI, tested with Universal Gui in LAB2A detection stops and blows shunt

Part Number: TMDSHVMTRINSPIN
Other Parts Discussed in Thread: MOTORWARE

Hi,

I try to evaluate the  TMDSHVMTRINSPIN Kit with F28069M CPU card.

My motor is a 250W water pump

With the InstaSpin-FOC GUI is was able to identify the motor.

I use the following setting:

Res st Current 1A
Estimated Freq 70Hz
Motor Pole Pairs 1
Motor max Current 1.5A
Motor Max freq 120Hz

I get these results

RS 75
LS_D and LS_q 157.35mH
Flux 3.5082767V/Hz

The system works well and i can spin up to 2400 rpm. 

With SVM Modulation set to 2.00

because i need 3000rpm i try switch to the recommended CCS LABs.

I entered my values in ccs 

#define USER_MOTOR_TYPE                 MOTOR_Type_Pm
#define USER_MOTOR_NUM_POLE_PAIRS       (1)
#define USER_MOTOR_Rr                   (NULL)
#define USER_MOTOR_Rs                   (NULL)
#define USER_MOTOR_Ls_d                 (NULL)
#define USER_MOTOR_Ls_q                 (NULL)
#define USER_MOTOR_RATED_FLUX           (NULL)
#define USER_MOTOR_MAGNETIZING_CURRENT  (NULL)
#define USER_MOTOR_RES_EST_CURRENT      (1.0)
#define USER_MOTOR_IND_EST_CURRENT      (-1.0)
#define USER_MOTOR_MAX_CURRENT          (1.5)
#define USER_MOTOR_FLUX_EST_FREQ_Hz     (70.0)

#define USER_MOTOR_FREQ_LOW             (10.0)          // Hz - suggested to set to 10% of rated motor frequency
#define USER_MOTOR_FREQ_HIGH            (50.0)          // Hz - suggested to set to 100% of rated motor frequency
#define USER_MOTOR_FREQ_MAX             (60.0)          // Hz - suggested to set to 120% of rated motor frequency
#define USER_MOTOR_VOLT_MIN             (80.0)          // Volt - suggested to set to ~20% of rated motor voltage
#define USER_MOTOR_VOLT_MAX             (240.0)         // Volt - suggested to set to 100% of rated motor voltage

after i enable and run LAB2A.

The resistance was measured equaly.

The the motor don't start spinning.

I uncheck "run" and "System enable" in the GUI after some waiting time. But don't switch off the system. After further 2 Minutes Shunt R11 blows up, Mains fuse tripped and the 15V Power Supply are in current limiting.

After some time without power the overcurrent on 15V is gone.

My questions:

  1. What might be properly damaged? R11 ! U1 ??? Are there some other critical parts?
  2. How i can get LAB2a to work?
  3. Why works the instaSpin FOC GUI so well and the LABs are a completly documentation and functional nightmare?

Thanks for all possible help and support.

  • Did you follow the lab procedure steps in InstaSPIN labs user's guide, load correct project for the EVM board, select your motor parameters in user.h ? And you don't need GUI if you want to debug in CCS.

    SVM Modulation can't be set to 2.00, it should be 0.5~2/3 or 1.0~3/4 which is based on motorware version.
