Hi,

this is the following post of  EVAL-M1-101TF configuration.

We changed our parameters as described in your replies, and test some other different values.

However, we always have a gatekill error.

Try 1 : in "normal" mode (angle select and CtrlModeSelect with value 2)

=> The motor always stop with a gatekill error about 160rpm. We think that it would be the transition speed from open_loop to motor_run mode.

Speed and IU unzoomSpeed an IU zoomedSpeed and Flux

We can see just before the gatekill that IU is increasing a lot.

Gatekill always occured at 160rpm.

Here is a video to the motor run :

Try 2 : in openloop mode (angle select with value 0)

=> We succeed to spin the motor at 500rpm without issue.

Here is a video of the spin :

Angle Select configSpeed and IU

Attached files are MCE configuration files.

Do you have any ideas on which parameters could I inspect to solve the issue ? (Flux, Iq, etc.) ?

Hello Community

If the source of a N-channel mosfet is connected to a negative high voltage, and the drain is connected to ground, is there any method to drive the mosfet, without using a isolation transformer ?

this is the problem I encountered  when I try to design a fast pulse generator to produce an edge rising from -4.5kV to 0.

please share your solution.

thanks 

Hi,

I am using I motion solution designer to tune my motor controller (IMD111T).

I can see some fault has triggered and the motor stopped.

Have no idea what this fault could be.

How to find the type of fault that occurred in I motion solution designer ?

I have another question,  how to set up field weakening with this new tool?

I cant find this parameter in this tool.

Hi Team,

I need some information related to MCE designer. Can you help me How to see V/F ratio in MCE Designer tool?

Thanks & Regards

Hi,

Here with, i want to know the Junction temperature (TJ in °C), Junction-to-ambient thermal resistance (ᶿJA in °C/W) & Junction-to-case thermal resistance ᶿJC (°C/W) values ofPVG612S-TPBF IC.

Kindly share the information mentioned above.

Thanks

Hello everyone,

I am evaluating with DEV_KIT_NAC1080.

https://www.infineon.com/cms/jp/product/evaluation-boards/dev_kit_nac1080/

Currently, I can access NAC1080 by registering 3 smartphones.
What is the maximum number of smartphones that can be used?

Best Regards

Hi guys,

Im a student and i need help. 

I bought a H-BRIDGE KIT 2GO.

I have 2 question : ( Im trying to do the shematic in the picture)

1) Does the PWM signal has a minimum freqency to work ? 

2) I can see 3 LED on the board i dont found their meaning on a datasheet ?

Thanks in advance,

Mathieu 

Hello!
is it possible to completely disable the short circuit protection of the IFX9201SG/TLE9201SG H-Bridge IC?
When I start the bridge driver, I get current spikes (which is quite normal), but the IC detects this as a short circuit and shuts down the IC. Is it possible to work around this behavior?

Greetings Silas
