Does the BTN8962TAAUMA1 console now have a QR code for screen printing? Is there a PCN file?
您好,想请教下, 关于TLE92104 SPI传输相关问题,
1. 我采用异步队列传输(QSPI加上DMA搬运), 会出错 .
2. 后来转成异步分别传输,不采用队列传输, 且一周期发一帧,工作正常 (一周期内异步传输, 一帧一帧的发也会出问题, 必须要一周期发一帧才正常)
请问, 该片子是不支持队列传输吗?每一帧传输需要中间间隔点时间吗?Show Less
MCE wizard does not support hall sensors with the duty cycle method, so can I give duty cycle to vsp pin (instead of throttle)? for the hall sensor.
kindly give any suggestions for work hall sensor with the duty cycle method. thanks in advanceShow Less
Im wondering that can imc101t be use for cnc axis control application? CNC axis control needs smooth drive at low speed and also needs high torque at low speeds. For example when using sensorless control , would imc101t can handle this application ? Or do infineon has a proper product for this application ?
I am using the IPM IM564-X6D and IMC102T-F064, and i use the same resistors as in the evaluation board.
I made a excel sheet to calculate the values for VTH and VFO based on the following formulas:
To be sure the values were correct i calculated the VTH value for 100ºC, and the value it gave was 2,58V, but in the Eval board User manual, the value for 100ºC is 2.33 V.
For 80 ºC it also gave a diferent value.
In my custom board based on the evaluation board, i measured the VFO and the values were near my results. But then i changed the IPM and the values where lower. The ambient temperature is about 20ºC.
I would apreciate if someone could check the excel sheet and confirm if the results are OK or not.
I am using an imc101t-f048 microcontroller, I want to run the motor at 3000rpm within 3sec, so I adjust the speed ramp rate
but when I set 450 rpm/sec in the speed ramp rate parameter, I continuously get a gate kill error. I pause the iu vs iv(trigger on fault) trace when gate kill occur it shows 52A and 50A respectively. From these results, I assume gate kill occurs when the current goes above the motoring current limit. My motor-rated current is 50A, I set the motoring current limit as 80%. I already verified the current sensing was good. I tried the current control mode but I cannot change the ramp rate.
I) Kindly suggest which parameter I need to adjust for my purpose.
2)which control mode I choose (now I am using speed control with duty cycle)
Regarding Infineon iMOTION, the motor works well if you don't connect UART to the MCE, But When UART is connected to the MCE, "CPU overload" and "Phase Loss" appear after a slight reaction at the start of the motor.
I've done several tests.
1. The data is transmitted very well.
2. AUX power is sufficient.
3. I think it's overloaded because we take a lot of data from the UART line in real time.
Is there any way to solve this problem?
Thank you for your response.Show Less
I have a EVAL_IMD700A_FOC_3SH and some new IMD700A-Q064X128-AA ICs just bought from mouser. I replace the IMD701A on EVAL_IMD700A_FOC_3SH with my new IMD700A. I turned on the power(PVDD:18V) ,VDDB and DVDD is working. But when I trying to flash firmware by BPA software, It keeps showing error message "Connection error:Please make sure the device is connected and swithed on"
Could anyone please give me some advice on this.
