Part Number: TMS320F28054M I have a drive working in instaspin technology for sensorless control. I am using trip zone input (TZ3) to trip the drive by using following code
in void HAL_setupPwms() function in hal.c file.
PWM_enableTripZoneSrc(obj…
Part Number: TMS320F28054M-Q1 Phenomenon: When the program is running, the motor itself will emit an electric current sound. As the voltage increases (12V, 24V, 48V, 110V, 600V), the current sound increases. The customer speculates that the phenomenon…
Part Number: TMS320F28054M I have developed a drive based on the instaspin technology. I have found out that if the drive reaches voltage saturation ( full speed) on no load and then if load torque(motor current) is increased, the current waveform starts…
Part Number: TMS320F28054M-Q1 device : TMS320F28054MPNQ
Phenomenon : When the program is running, the motor itself will make a current sound. As the voltage gets higher (12V, 24V, 48V, 110V, 600V), the current sound gets louder.
The customer speculates…
Part Number: TMS320F28054M-Q1 Other Parts Discussed in Thread: MOTORWARE Hi Expert，
Nice to talk with you.
F28054M-Q1 is under evaluation on customer side. The application is motor controller of Brake system. Here is the background for this customer…
Part Number: TMS320F28054M Hi,
I have a custom low induction sensorless outrunner motor, which I use InstaSPIN FOC to control. Sometimes, especially when the stator resistance (Rs) is estimated too high, I get a weird shaking behavior when the speed…
Part Number: TMS320F28054M I have a strange issue.
I have a custom hardware and software designed around 28054M instsaspin based processor. I have ported necessary code snipets from overmodulation lat10b in my code. The modulation index used is 0.6666…
Part Number: TMS320F28054M Hi, I need some tips on how to maximize the start torque when using InstaSPIN FOC+MOTION together with a low-inductance sensorless motor. I have read through chapter 14 in the instaspin user guide, and have enabled all recommended…

Today I ran into a strange issue I have not experienced before. I have…
Part Number: TMS320F28054M Dear experts,
The customer requires a heavy load during the motor start-up, but does not allow the motor to rotate during the initial position phase. They thought that the instaSPIN-FOC needed to be rotated a certain angle…
