Motor Control ICs Forum Discussions
Hello,
We are using the IMC101T as motor control IC. I could not find any reccomendation or guidelines about what to do with the unused Digital or Analog pins in the datasheet, application notes.
The only text I could find is from the datasheet: "Pins that do not have any signal assigned are reserved for future use. These pins should be left unconnected and neither be connected to ground nor to the positive supply." I believe this tet refer the unused chip pins, for example pin 13 or 14 from the IMC101T-Q048, which do not have any function.
But what about any GPIOx o AINx if Im not using these pins?
Thank you.
Show LessWe have started the infineon IMM101T-015M IC evaluation, for our motor to tune we took a competitor board with an infineon solution from that trying to connect the IMOTION LINK Isolated debug probe found below message from MCED designer. images below,
i connected as per imotion guide

I am using the EVAL-M1-IM828-A and EVAL-M1-101T to prototype a BLDC motor application with sensorless control and open loop start-up.
I am having some difficulty in tuning my motor. The motor accelerates smoothly to the “minimum running speed” set in question 9 in MCEWizard. Once it reaches this speed, the motor stalls. It shudders / turns very slowly for a few seconds after stalling before a gatekill fault shuts it down. I believe that this stall happens when the controller transitions from open loop to closed loop control.
- Is there a guide that explains the process of tuning a BLDC motor using MCEDesigner?
- MCEWizard gives three motor control mode options: speed control, voltage control, and current control. Can these be used to tune each of the control loops independently? The description above is what I observed when the motor was in speed control mode. In voltage control mode, the motor does not turn and trips a gatekill fault almost immediately.
- I would like to use the scope features in MCEDesigner to monitor motor parameters while tuning. Some of the preconfigured traces work (for example, “Iu & MotorSpeed”), while others do not open. In particular, I would like to see a trace of target speed and actual speed, but any monitoring group with the TargetSpeed trace will not open.
Thanks for your support!
Show LessHi,
Hi,
Its possible to do DC injetion to the motor using iMotion Control?
If not, is there a way to lock the motor in place using iMotion?
Best Regards,

Show LessHello,
I started using iMotion Solution Designer, and with that i had to change the addresses of the variables i read and write by UART. After changing everything, all works, but when it comes to read/write global variables in the script, i don't get a reply by UART.
For example, when i want to write to BusVoltageLimit, i use FB_ID -> 0xF0 and register_ID -> 0xFC, but sending a uart message with those IDs does not give me a reply.
I am sure that the script and parameter are properly downloaded, and that the xml file im using to see the id's is the most update. The problem is just in the user variables of the script, because i can read/write variables from system and parameters, and can also read Script User Version.
Is there any extra steps i need to make?
If someone can help me i would apreciate it.
Thanks
Paulo
Show LessTitle -- is BTN7030-1EPA a drop-in replacement for BTM7710GXUMA1?
I'm setting up my IMC301 via MCEDesigner. Once this is done I would like to change a few basic control parameters over the user UART. I am only running an induction motor with it! It looks like I can change motor current limit with register 32, I've not tried yet as I also need to change the number of poles on the motor but cannot see a register for this.
Is what I am proposing possible?
If so is there an easy way to cross reference the parameters in the text file output from MCEWizard to the registers I need to change as this is where I'm really struggling.
Thanks
Jonathan
