Hi Chirag,
Just incase there is a misunderstanding, I will clarify that the PWM values you mentioned for the MCT8329 and MCF8329 are the max electrical frequency which is the same as the max speed of the motor the MCF and MCT algorithms can support. This…
Hi Matthew,
JSON is EEPROM values which are tuned for the motor and application requirement.
It is better to use EVM, tune the motor and once we are convinced about the performance then use that JSON (Tuned set of arrays) or EEPROM values in your host…
Hi Nguyen,
1. Can you measure the phase voltage and check the PWM output frequency?
2. Can you test with the PWM_FREQ_OUT set to 15 kHz and 25 kHz to see if using these values correct the issue?
Regards,
Joshua
Part Number: MCF8329A Tool/software: Hello,
Can you help us understand how to calculate the base current on the MCF8329A?
The data sheet isn't very clear.
current sense resistor 0f 0.5mΩ
current sense gain of 20V/V
expect an RMS current of…
Part Number: MCF8329A Other Parts Discussed in Thread: EV2400 , MOTORSTUDIO , MCF8316A , MCT8316ZTEVM , MCT8329EVM Tool/software: Hello,
Can MCF8329A handle 4.35V cell in 12S config? I see Abs V as 60V instead of 65V on most other gate drivers. Will it need…
Hello Venkatadri, Sorry for late reply, we tested with motor studio as you suggested and we got correct values. After that, we went through our code and we were able to solve the problem, we were reading the result with no sign, instead of positive and…
Hi Muhammet,
The MCF8329A provides list of registers to read the speed of motor
FG_SPEED_FDBK - This value is updated based on FG pin and this can be configured to show FG even when motor is coasting
SPEED_FDBK - This shows estimated speed and this shows…
Part Number: MCF8329A Tool/software: Hello, I have a medical device using two motors, each motor attached to one MCF8329 on same I2C BUS. I have change the DEVICE_CONFIG1 to 0x00200002, but the MCF8329 still accepts command on the I2C bus with the default…
