Part Number: MCF8329A Tool/software: Dear TI engineer, hello. We are developing a high-sensitivity hair dryer that needs to achieve a fast acceleration from 6000 to 30000 revolutions per second in 0.1 seconds. We have tested it with other driving schemes…
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…
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…
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
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…
Hi Lin,
Request t0 start new thread for this topic, it helps us to improve to track open threads and re use the conversation which solved similar issues.
I will attend the new thread which you can help by creating, sorry for the inconvenience and appreciate…
Part Number: MCF8329A Tool/software: Hello TI Expert,
In the before topic, I received some corrections for the EVM from TI about [How to Calculate Base Current].
Please reference this link: e2e.ti.com/.../5316025
In another application with MCF8329A,…
