Motor Control ICs Forum Discussions
Hi
We decided to continue open a new thread for gatekill errors and motor shaft movement troubles. İf you interested to read old posts of mine about connection and some parameter errors you can visit here ;
https://community.infineon.com/t5/Motor-Control-ICs/imc101t-fail-to-disconnect-error/m-p/391770
So assumed that we can continue here.
As you can read at above link , i have shared some of the new problems that i faced at my imc101 chip since i resoldered brand new controller ic.
I have stuck there and need some help
Thanks

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.

Hello i have two questions about the class b certification of the IMC102 imotion
- which testing institute has tested the Class B ?
- is there any more information about this topic ?
- is the scripting also part of the Class B certification ?
thank you very much
Show LessHello,
iSD(iMotion Solution Designer) cannot access package site ?
hi
im having trouble with imc101t048q chip to connection with my pc. Chip soldered to designed test board. Here let me tell about what i have done at this time;
I m using generic usb to ttl converter module for programming imc101t using my pc and was first attemed worked well. I have programmed chip when power up the circuit board. After that connection have done and there was no problem for comminication between pc & imc101. Even i could turn my servo motor with this board. After a accident i burned my imc101t. Then i ordered new 3 chips from farnell and they arrived today. So my today's job was repair board with new imc101 chips.
I have soldered and tested board before apply any voltage to it and we see that there is no error or problem at all. Then we apply voltage to it and 3.3v was ok for imc101. At first oneof the gpio pin of imc101t was flicking/blinking randomly before upload program or firmware to it. Using same usb ttl converter module i could succesfully upload firmware and program to it. During this time, i noticed that some of the other gpio pins of imc101 was on( attached led to them) by flicking or blinking or even slightly lighting. That was weird because i havent got any script on my program and at first chip which is burned before had no response of gpio pins, althought i used same program.txt file for new chips. After first program was done i was not able to program it again. Everytime i try it says that " failed to disconnect port" . I have tried to program it with power up my board when usb connected to my computer. I have waited and even fully discharged all capacitors from 3.3V but result didnt changed.
At that moment, i have think that maybe chips is broken too and i decided to replace with new one . Then result was the same as the old one , gpios started to blink / flicking randomly and unexpectedly before upload and firmware or program into it (fully empty chip)
I have tried to explain my problems as much as i could. Please help me about it .
Thanks.

When I change dead time from 2us to 4us using MCEWizard, programming my IMC101 with MCEDesigner, and loading that parameter set, the drive waveform doesn't seem to change at all. It looks like the dead time is stuck at 2.0 us. I have already examined the parameters ".txt" file and see that it has different values after changing the dead time is MCEWizard.
Is there something else I need to do to adjust the dead time?
Show LessHello,
I have just downloaded the Solution Designer and I realised that the motor current (Inverter rated current) can only be adjusted to 100A max.
In the "old" MCE Wizard it could be adjusted to higher values.
Is it possible to enter a higher value than 100A? (300A?)
Thanks

Show LessHi,
I am using IMM101T-046M with STM32F303CBT6.
How to handle the PWM & Analog Input through an External MCU?
What are the changes I want to do in the Parameter file?
Thanks

Show LessHi sir, I am trying to find a suitable solution for heating and cooling of a special part of my circuit. For that, I have chosen a Peltier element and would like to use an Double BTS7960 43A H-Bridge motor driver module with a PWM Control. This H bridge module suitable for the regulation of the Peltier element polarity changes?
The Peltier technology
Heating and cooling in a single system: If a voltage is placed across a Peltier element, one side is cooled and the opposite side simultaneously heats up. Simply by reversing the polarity of the supply voltage, the hot and cold sides of the Peltier element can be swapped.
peltier volt: 12v to 18v
peltier load current: 15Amps
I’ve attached the datasheet of this BTS7960 43A H-Bridge module.
Kind Regards,
Kumar
