我最近阅读了TLE9183QK的安全手册,在figure 5 的流程图里面(self test of UV_VCC),在uC做完“bit st_uv_vcc reset in Sel_st_1”之后,有两个分支:①exit self test mode→reset with ENA②reset with ENA→bit st_scd_hs set in Sel_st_1。我的问题是
这两个分支都需要执行么?
有没有预置条件?
特别是②的最后一步“bit st_scd_hs set in Sel_st_1”是必须要做的么?

I recently read TLE9183QK's safety manual. In the flow chart of figure 5 (self test of UV_VCC), after the uC finishes "bit st_uv_vcc reset in Sel_st_1", there are two branches: ①exit self test mode→reset with ENA②reset with ENA→bit st_scd_hs set in Sel_st_1.
My question is, do these two branches need to be executed?
Are there preset conditions?
In particular, is the last step of ② "bit st_scd_hs set in Sel_st_1" necessary?
Show LessI have a problem with IMC101. When i'm trying to use sensorless pmsm with InitialSense sometimes motor rolls back at start up. So i want to use 3 digital hall sensors for correct start. But how could I do this without using Hybrid PLL Mode? ( At low speed hall sensor works worse then flux pll) Show Less
When resetting the slew rate on the IS pin, I understand that Feedback Temperature is set in SR Selection Mode, and after Current SR Feedback, INH = 1 when the specified SR level is reached. For example, if the SR level is SR4 in Current SR Feedback, does it start from SR5 next or from SR0?
Show LessHi 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. *
Show LessHi,
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,
K
Show LessHi,
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 🙂
