Motor Control ICs Forum Discussions

Hi Team,

We are doing some experiments using the IMD111T. We want to run the motor using my power board and Infineon IMD111T motor control IC. We did connect all the required cross wires between the IMD111T solution and my power board. We can do parameter and software programming but cannot run the motor-identified gate kill error.

Could you please help me on this how to overcome the issue.

I have two EVAL boards.

IM818 and IM828.

The difference between these two is Leg-shunt and Single-shunt.

1.If I set the high-speed RPM, the LEG-shunt goes up to the high-speed RPM well and maintains it well.

2. However, If I set the high-speed RPM, the single shunt cannot go up to the high-speed RPM and comes down again.

For example, If I set 2000 rpm, it goes up to 1600 and then drops back to 1000.

Can't single shunt drive at high speed?

Please reply.

Hello.

I captured the part I measured. Please check the picture.

When measuring the Back EMF, I told you to turn the motor by hand, but the measurement value is different every time I turn it hard or weak by hand, so what should I do about this part?

Calculation and measurement are too difficult for Back EMF measurement. Help me, please.

I don't know how to handle the scope and it's hard to calculate even.

 No matter how much I read the data, it's difficult for me.

This is the value I measured. Please look at the picture and make sure it is correct.

1. LS : 21.941mH
2. Resistance : 3.8ohm
3. Back EMF : ?....

I looked at the reference design and did the same Legshunt design, but the IPM keeps exploding.

Overcurrent continues to occur.
Is this reference design correct?

I can send you my design schematics if you'd like.

I keep getting a "Gate kill" error no matter what value I enter.

* It doesn't seem to be a parameter issue. I bought and tested the IM818's EVAL board and the EVAL board had no problems. *

Hi,

I am working with the Infineon IMC101TF048XUMA1 motor controller for controlling a PMSM motor for an underwater thruster.  All is up and running on a custom designed drive board attached to a EVAL-M1-101TFTOBO1 development board as you can see in the photo below. Also am using 6 of Infineon MOSFETs, IPTC019N10NM5 per board.

In our existing configuration, the motor operates smoothly up to around 1100 or 1200 rpm, unloaded in air. However when commanding the motor up to a slightly higher speed, it is getting a Over Current fault (GK). It runs fine at all speeds below this speed while increasing and decreasing speeds in this range. It also works fine in both directions. We have setup all motor parameters to match. Adjusting the other parameters has not helped to this point. I have turned up the guard band to 5 microseconds which helped us reach a slightly higher speed, but we still get the faults when running above 1200 rpm.

I have attached a schematic as well as the most recent setup files for the IMC101TF. (Unfortunately, this forum only allows certain doc forms, so I converted to PDFs for some)

Power supply rails (battery at 70V, DC and Vgs at 12V and linear regulator at 5V for the motor controller) remain stable during operation.

Does someone have any idea what would cause issues when a certain speed is reached with this setup?

Hi there,

I am using TLE9201SG H-bridge drive and have a requirement to control the 24V actuator using PWM.

Since there is a PWM input pin on the drive, the microcontroller is sending 1KHz at 50% duty PWM signal into the PWM pin.

I am expecting to see one of the output pins at 0V, which I do, and the other output pin at 24V PWM of 1KHz at 50% duty.

I am, however, seeing a clean 24V on that output.

Am I missing something? There are not a great deal of control pins on this h-bridge used to control the outputs..

Thanks a lot for your help,

Kind regards,

Hi,

I have developed a controller board based on REF-Fridge_D111T (https://www.infineon.com/cms/en/product/evaluation-boards/ref_fridge_d111t_mos/).

The control mode I am using is current control mode.

When I start the motor in no load,  it ramps up too fast to high speed 16000RPM and gate kill is triggered.

How to slow down the ramp rate in current control mode?

For some reason, when I try to control the speed using Vsp analog input with current control mode, the motor starts and then immediately spins in opposite direction. what can cause this issue? 

Thanks 🙂

Hi,

I am designing a controller for PMSM where the torque increases gradually with speed.

I have developed a controller board based on REF-Fridge_D111T (https://www.infineon.com/cms/en/product/evaluation-boards/ref_fridge_d111t_mos/).

I am controlling the speed using Vsp analog input.

The maximum speed of motor in parameter file is 18000 RPM.

It's an IPM motor with field weakening current limit of 100%

The motor can run up to 18000 RPM at no load,in field weakening region without any issues.

But If I try to run the motor with load at 18000RPM,  at some point (14000RPM) the load torque is more than motor  torque, and controller goes out of control and the gate kill is triggered. The speed at which the gate kill is triggered depends on the value of load torque. 

The behavior I am expecting from the motor is , instead of triggering gate kill and stopping just keep running at lower speed (maximum achievable speed for the given load torque).

Just to give you more details on my application,

Different loads will be applied to the motor manually, so load torque is a variable.For different load torque the attainable maximum speed of the the motor will vary. 

If I set up maximum speed as 18000RPM, then loading the motor with higher loads will trigger gate kill at 14000RPM. Instead I want the motor to run at 14000RPM without stopping. 

Please give me some ideas on how to configure this?

Thanks:)

①IN Register 0CH,field 3:2 is called fm_osfb,which means"output stage feedback failure behavior". Question is :how to understand feedback failure in real application scenarios?

② how understand high-side and low-side?

③what is ART mode？

I have an EVAL-M1-101T-T038 and an EVAL-M1-IM323. I have not used any Infineon products before. I have watched several videos including How to get started with iMOTION™ 2.0 by Infineon4Engineers. I have also read the user's manual.

I downloaded the latest MCEWizard and MCEDesigner (both v 2.3.0.1). I setup the motor parameters in MCEWizard and saved the file. When I attempt to open an irc file in MCEDesigner I get Error: Could not open file (x86)\Infineon\iMotion2.0\MCEDesigner_v2.3.0.1\IMC101T_v1.03.03.irc. I read in the forum that if this occurs you should uninstall both software packages and install an earlier version. I did this and installed version 2.2. I got the same error. I uninstalled v2.2 and reinstalled v2.3. To make sure that I didn't have a corrupted IMC101t**.irc file, I downloaded the irc file for the IMC101T-V1.02_20_iMotion2Go and got the same error. I have a USB cable connected to the EVAL boards and they are powered. I am running Windows 7 sp1.
