Motor Control ICs Forum Discussions
hi can anyone advise me of the cause of a problem that I have.
I have built a PCB that is a copy of the evaluation pcb schematic. It is being controlled by the duty cycle input.
the board functions turning on and off as requested, but the three high side pwm outputs are all being produced at the same time. so the motor is not being driven.

I have exactly the same problem as already described in this link. It says that it has been solved. As I understand it I have not solved the problem yet?
In any case it still works for me. In any case, it still works for me. all points connection, build, flash, etc. were successful.
thx
Show Lessmotor parameters:
220vac,maximum power:1.2kw
rated Amps: 10A
Poles: 10
Stator resistance: 3.15ohms
Lq inductance: 0.93mH
Ld inductance:0.93mH
Back EMF constant: 7.46V/krpm
Max RPM: 15000RPM.
the Ques60 - Flux Estimator Time Constant, I write 5 times the motor time constant( L/R):5*3.15/0.93=1.48.
When I calculate parameters, the following error prompt appears:
Would you be able help? any suggestions?
Thanks
Show LessHi,
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.
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 :
Attached files are MCE configuration files.
Do you have any ideas on which parameters could I inspect to solve the issue ? (Flux, Iq, etc.) ?
Show LessHi,
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.
Show LessHi,
I am using IMM101T-046M IPM.
If the pump got seizes, How is it will Handle it?
Thanks

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 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
