Hi everyone,

I have a question related to the EVAL-M3-IM564, in the user manual it says that the input voltage is from 165V to 265V, but in my project i will need to have an input of 110V 60Hz or 220V 50Hz.

1 - What changes would i need to make to the eval circuit to be able to use both 110V 60Hz and 220V 50Hz?

2 - What would be the implication on the output power?

3 - Would i need to change configurations for the motors, or only PFC?

 

Best Regards,

Paulo

Hi, I'm new and I have this problem where if ai try to combine the files in MCEWizard it is all gray and dose't let me click anything, is there something i can do? Show Less

Hello everyone,

I am having  problems related to sensing current and controling current limits using a induction Motor.

This post is related to my previous post: Motor Current Register in iMotion - Infineon Developer Community, but since i didn't get reply's for some time i am starting a new post.

 

I am controling the motor using voltage control, and i followed this aplication note: Induction motor control by iMOTION™ (infineon.com)  I think the control of the motor is good, and im changing the speed using duty-cycle control.

But in my aplication i need to be able to limit the current that the gate can draw.

When i was testing the evaluation board i had used MotorLim, and putting diferent values would have an effect on the motor current. But now, in my custom board nothing happens, even if i put 150% or 50%, the current is allways the same.

My aplication requires another safety measure, that is to allow the motor current to go above a treshold only for a few ms before giving an error. For that i am using the Script in MCEWizard. In that script i want to use the MotorCurrent, since it should already be in RMS. But what when i read that register in MCE Designer or by UART i always get a very variable value.

When i tested in the evaluation board i would get the RMS value as expected:

 

Print taken in MCE designer with evaluation boards, the current value is in RMS.

 

Print taken in MCE designer with custom board, the current value is very variable.

 

What can cause this problems i am experiencing?

If someone can help i would apreciate it.

Best Regards,

Paulo

Hi,

I am evaluating the REF-MHA50WIMI111T board and I am attempting to use an low cost off the shelf isolated USB to TTL interface to connect to the target board.  The interface uses an FDTI FT232RNL chip.  It has isolated data and power.  I do not connect the Vcc of the interface to the target board.  Only Txd, Rxd, and Gnd.  It is able to connect and program my configuration and even start motor motion, but It seems to lose connectivity often and at random.  I would prefer not to have to buy the Link interface that is specified as it seems to have features I don't need.  The device I am using is found here:

https://www.amazon.com/dp/B07TS3GPQ1

I have it jumper configured for 3.3V operation and I verified with a scope that the TX signal levels are at 3.3V.  It also seems to loop back on itself fine.  I am connected to my desktop USB port via a 6 foot USB extender cable so that the interface is located very close to the target board.   Is there any thing I can do to use this or some other low cost interface to work with this board?

Regards,

Mark

Hi there, We use the IMC101 for motor control where the DC link is supplied by a 3ph diode rectifier. Thus the DC link voltage ripple is 6 times the line frequency. At high powers, I can see that the ripple in DC link voltage directly affects the Id, Iq currents even though I have enabled DC bus compensation in the settings. The ripple in Id, Iq seems a bit too high for our application (20% peak to peak ripple in Iq seen at average Iq of 50%). The DC link sensing circuit on our board works fine as I verified the ripple in Vdcraw signal with iSD oscilloscope against real measurements. Can you comment on why the DC bus compensatoin might not be working as it should? Show Less

Hello.

I am using the iMotion Solution Designer.
The pfc is also in use. 370v is the target voltage.

Speed control is used to operate the motor.
The current motor voltage is variable (150-350 VDC), the motor current is maintained at approximately 1 A and the motor RPM is controlled.

However, when the motor RPM is 3600, I want to maintain about 180V and control the voltage Vdc by adding current.
In other words, we want to limit the maximum motor voltage.
What am I supposed to do?

Thank you

I am trying to implement UART FIFO Mode protocol implementation in IMD111T-F040 Microcontroller. I taken the this pdf as reference(Infineon-AN2021-10_How_to_Use_iMOTION_Configurable_UART-ApplicationNotes-v02_00-EN). This pdf has FIFO and Buffer mode protocol implementation sample programs but we don't have pin configuration details. So, while i am trying to implement the FIFO Mode the data transmit from microcontroller is working. But whatever data is i sent to microcontroller the interrupt is not generating(data receiving is not not happening). So can you please answer my questions Questions: 1. can I enable or disable solution designer com port? 2. can I declare Tx and Rx pin configuration(Input or Output)? 3. currently i am using FW 5.03.07. So is UART support or not in this version?
