Greetings! I have a three phase ACIM connected to my board with these parameters -> Power=250W, Nominal current 1.4A, RPMs=840, Nominal voltage 380V, 50Hz. There wasn`t an appropiate example motor settings in the user.h, so I made my own using the my_motor_1:
#define USER_MOTOR_TYPE MOTOR_TYPE_INDUCTION #define USER_MOTOR_NUM_POLE_PAIRS (8) #define USER_MOTOR_Rr_Ohm (69.75102) #define USER_MOTOR_Rs_Ohm (57.8) #define USER_MOTOR_Ls_d_H (0.216) #define USER_MOTOR_Ls_q_H (0.216) #define USER_MOTOR_RATED_FLUX_VpHz (0.8165*230.0/60.0) #define USER_MOTOR_MAGNETIZING_CURRENT_A (NULL) #define USER_MOTOR_RES_EST_CURRENT_A (0.2) #define USER_MOTOR_IND_EST_CURRENT_A (NULL) #define USER_MOTOR_MAX_CURRENT_A (1.4) #define USER_MOTOR_FLUX_EXC_FREQ_Hz (5.0) #define USER_MOTOR_NUM_ENC_SLOTS (NULL) #define USER_MOTOR_INERTIA_Kgm2 (2.12002e-05)//I am not sure about this parameter I took it from the examples #define USER_MOTOR_FREQ_MIN_HZ (2.0) // Hz #define USER_MOTOR_FREQ_MAX_HZ (60.0) // Hz #define USER_MOTOR_FREQ_LOW_HZ (10.0) // Hz #define USER_MOTOR_FREQ_HIGH_HZ (50.0) // Hz #define USER_MOTOR_VOLT_MIN_V (80.0) // Volt #define USER_MOTOR_VOLT_MAX_V (380.0) // Volt
So now when I start the is04_signal_chain_test I hear a lot of noice comming from the motor, but there is no movement! I`ve tried to modify the parameters motorVars.speedRef_krpm, motorVars.IdSet_A and motorVars.IqSet_A as the doc suggests. I`ve reached 0.8 for motorVars.speedRef_krpm and 1.5 for motorVars.IqSet_A. I`ven`t touched the motorVars.IdSet_A(0.0 by default). There is no change. I`ve tried the next example is05_motor_id and again -> a lot of noice from the motor, but no rotation.
Any ideas?
Thanks!
