Hello,

I have MADK board EVAL-M1-301F. In the user guide I found that:

Access to MCU via SWD debug channel (Segger® J-Link light)

Looking through schematics I cant find needed signals in the isolated part of the board. I can only see that connector X102 has traces with the on board debugger XMC4200 pins P2.4, P2.5, P2.8.

Could you clarify the X102 connector pins purpose and how to program the MCU of the IMC301A-F064 in this board? (Keil uVision5 CMSIS pack installed, code compiled, do not know how to properly flash and debug).

Hi@Krupashanka

                                        I am making project by using Eval-M1-101TF & Eval-M1-IM535 power board to Run air-condition inverter Compressor having BLDC DC motor.  I am Getting 2 Error in Mce designer  

1. RMS Current as per compressor Catalogue Gmcc 1.5 attached also.  Current Compressor input is 4.2A, RMS will be 4.2*.707 is 2.96. but MCE Wizard Accept value 1.5  or Below as RMS current.

2. Parameter give Error same in DC Bus under Voltage level I try to Enter 260V but it give Error only

Accept 6V or Less Value.

Compressor Manufacturer Catalogue is also Attach. Pl Guide what I am doing Wring.

Thanks 

We are using 3 BLDC motors which are having Continuous Phase Current of 5A, Peak Phase Current is 22A (1 Sec). Suggest me the suitable and available BLDC Driver module. 

    I have made user UART communication between General MCU and imc101t. I can control the motor using the write register command.  in my MCU uart program, I judged that the communication with imc101t was interrupted, I reinitialized my UART, but I still can't communicate with IMC101T.  After power on again, the communication returns to normal.

    Because the product is in the customer's place, I can only see that the parameters of imc101t are not updated through the HMI. Moreover, the communication interruption is an accidental event, and I can not judge whether it is the problem of MCU or the problem of imc101t.

      how can I solve the communication failure? How does imc101t  handle link break ?

Hi,

I have used IC IMC102 controller Motor to start the motor.

In the configuration MCE Wizard, I set the switching frequency (inverter =Fsw=6Khz & PFC= Fsw=55Khz).

But because the switching frequency of the inverter is 6Khz , the sound noise of the motor is high and this is annoying.

On the other hand, with the increase of the switching frequency of the inverter, ،Total CPU load becomes more than 90%.

I need frequency switching PFC 55Khz  and Fast control rate =1 ,

What solution do you offer to remove audio noise without increasing Total CPU load?

Best Regards.

Hi,

I have a EVAL-M1-101T board which has IMC101T -T08 MCE on it. the eval board also has XMC4200 as the onboard debugger. The board is connected to PC via J Link and Matlab can see the COM port. 

How can I read the registers and send command using Matlab?

Thank you for your help!

Hi I have IMC30A eval board and I want to use the PFC feature to provide  pfc and universal input voltage. But I cannot find any resources to calculate the required inductance for the application. 

Design requirement:

Input voltage: 85 to 240VAC(50-60Hz)

load current max 2.5A(RMS)

Please help!

Hi,

I am working on bringing up a custom board. We have a lot of experience with the IMC101TF048XUMA1 and have integrated this into our design. I am using a iMotion-Link to attach a PC to the board for programming. I am trying to establish the initial communications and to program the initial Firmware onto the IMC101TF048XUMA1.

I can see the UART signals (0-5V) arrive at RX0, pin 45 on this part, but there is no response.

I have also verified on an oscilloscope that the signal is as expected. It arrives at the pin with clean transitions, and I used the same 'scope to verify the UART signal as a series of 4 bytes from MCEDesigner - as you can see on the plot below. Here you can see the incoming signal on the bottom trace. Of course, to look for the response I also zoomed out and looked to the right and found no response from the TX0 pin 46, nor did the MCEDesigner app connected to the port.

One thing I did notice is that the pulses measure at an equivalent of 113.2kBaud rather than 115.2kBaud. This is what the iMotion-Link generates. Is this enough to cause the signal to be rejected by the IMC101?

Any thoughts on any reason why the  device might not respond to this signal?

Here's a schematic snippet for reference. We are using 5V for power, and power is applied to the board.
