Hello Dear,
I am using Hardware TMDSHVMTRINSPIN and Software Instaspin lab's. I am connecting servo motor with it.I have several questions about it but here the motor parameter
#define USER_IQ_FULL_SCALE_FREQ_Hz (USER_MOTOR_NUM_POLE_PAIRS/0.008)
#define USER_IQ_FULL_SCALE_VOLTAGE_V (2100)
#define USER_ADC_FULL_SCALE_VOLTAGE_V (700)
#define USER_IQ_FULL_SCALE_CURRENT_A (10.0)
#define USER_ADC_FULL_SCALE_CURRENT_A (20)
Reference for labs :1) InstaSPIN Projects and Labs User’s Guide , 2)InstaSPIN-FOC and InstaSPIN-MOTION
Motor rating : (rated voltage = 75 V , rated frequency = 200Hz , rated current = 1.1 A , rated speed = 3000rpm )
I have questions for lab 2B
I have three question for it
1) In lib 2b I have got error of USER_ERRORCODE_VOLTAGE_SF_LOW , So I reduce the ratio up to 1 than the error was eliminate. but the reference guide say we have to maintain ratio of (1/3) at least. So where I am wrong?
2) USER_IQ_FULL_SCALE_FREQ_Hz means which value I have to write?,because as per guide it must have to more than maximum speed but if I am put 5000 Hz , than it's gives me error of USER_ERRORCODE_VOLTAGEFILTERPOLE_HZ_LOW.
3) which parameter help to increage supply voltage to motor from 340 V DC Bus.
4) In lab 2b the motor identify Rs and Flux but Not Inductance value It's show error of estimation.
