Our motor is a system that drives the motor by sending commands to the app.
It worked well until last week, but it suddenly doesn't work from this week.
I have no idea why.
The app entered the rpm value and sent the command to the IMC101T-F064 chip, but no response was received
The motor is not working.
If you enter the parameters on the IMC101T-F064 chip, you will get this error.
Is this the cause?
Please reply.

Hi @JasonLEE,
Possible cause of communication error:
-
This problem could be due to weak drive signal strength. Please use RS232 line driver and receiver for UART communication.
- We could see in the configuration file ( Setting.mc2) Ques 24: Controller supply Voltage is at 3.3V but in schematics, we could see supply voltage at which iMOTION controller operates is 5V. Please change this parameter to 5V.
Please use the recommended connection in thread: IMC102T-F064 port error. Hope this solves your issue
Please let us know if any further clarification is needed.
Thanks,

Hi @JasonLEE,
This problem could be due to the following reasons:
- Connection issues between IMC101T and UART device
- Firmware mismatch
- Incorrect Register map file
Can you please let us know if you have made the connections mentioned in the thread: IMC102T-F064 port error.
Can you share the firmware version? we assume other details shared are the same as in the earlier thread.
Please let us know if any further clarification is needed.
Thanks,
Krupashankar

Hello.
Thank you for your reply.
I changed the chip to IMC101T-F064 From IMC102T-F064,
The reason is that we do not use the PFC function.
But after changing the chip, UART doesn't recognize it.
The command was sent successfully, but I don't know why it's not recognized.
My firmware system is as follows
ESP32-> ATMEGA2560 -> IMC101T-F064
This is the system.
Therefore, Atmega sent the command to the IMC101T-F064 chip, but there was no response.
There was a reaction when IMC102T-F064 chip was used before.
I want to know why IMC101T-F064 is not responding.

Hello.
I solved the problem.
But a lot of questions remain.
UART communication is very good because I changed it to IMC102T-F064 chip.
I don't understand why this problem occurs when I use the same firmware.

Hi @JasonLEE,
Glad you could solve the problem.
The same firmware cannot be used for two different controllers
IMC101T- IMC101T-T038 MCE Software Package v1.3.3
IMC102T-IMC102T-F064 MCE Software Package v1.3.3
Hope this solves your problem and can you please create new thread for remaining questions
Thanks,
Krupashankar

I said it wrong.
This is a parameter.
I used the same parameters
IMC101T-F064 doesn't have UART communication
The IMC102T-F064 has excellent UART communication.
I don't quite understand this part.
Anyway, the problem is solved.
Thank you for your answer.
