Motor Control ICs Forum Discussions

Hi everyone,

I am using the IPM IM564-X6D and IMC102T-F064, and i use the same resistors as in the evaluation board.

I made a excel sheet to calculate the values for VTH and VFO based on the following formulas:

To be sure the values were correct i calculated the VTH value for 100ºC, and the value it gave was 2,58V, but in the Eval board User manual, the value for 100ºC is 2.33 V.

For 80 ºC it also gave a diferent value.

 

In my custom board based on the evaluation board, i measured the VFO and the values were near my results. But then i changed the IPM and the values where lower. The ambient temperature is about 20ºC.

 

I would apreciate if someone could check the excel sheet and confirm if the results are OK or not.

Best Regards,

Paulo

hello all,
I am using an imc101t-f048 microcontroller, I want to run the motor at 3000rpm within 3sec, so I adjust the speed ramp rate
but when I set 450 rpm/sec in the speed ramp rate parameter, I continuously get a gate kill error. I pause the iu vs iv(trigger on fault) trace when gate kill occur it shows 52A and 50A respectively. From these results, I assume gate kill occurs when the current goes above the motoring current limit. My motor-rated current is 50A, I set the motoring current limit as 80%. I already verified the current sensing was good. I tried the current control mode but I cannot change the ramp rate.
I) Kindly suggest which parameter I need to adjust for my purpose.
2)which control mode I choose (now I am using speed control with duty cycle)

Regarding Infineon iMOTION, the motor works well if you don't connect UART to the MCE, But When UART is connected to the MCE, "CPU overload" and "Phase Loss" appear after a slight reaction at the start of the motor.

I've done several tests.
1. The data is transmitted very well.
2. AUX power is sufficient.
3. I think it's overloaded because we take a lot of data from the UART line in real time.

Is there any way to solve this problem?

Thank you for your response.

Hello there, We are trying to tune the IMC101 for motor control for a PMSM. We believe the current feedback works okay. But when we try the closed loop current control with Flux PLL for rotor angle feedback (which means speed control loop is disabled), we see low frequency current ripple on top of the fundamental currents. Reducing the current controller BW seem to help, but it needs to be too much reduced compared to our requirements. I am starting to wonder if the flux PLL gains need to be tuned Question 1: Do you think the oscillation we see in current could be related to the observer or do you have other suggestion to trouble shoot the problem? I do not find any documentation (in either the functional/software reference manual) on how to set the PLL Kp and Ki gains and how the Kp/Ki gains relate to the bandwidth of the flux observer. Question 2: Are you able to provide some details on the flux observer tuning? Show Less

I have a EVAL_IMD700A_FOC_3SH and some new IMD700A-Q064X128-AA ICs just bought from mouser. I replace the IMD701A on EVAL_IMD700A_FOC_3SH with my new IMD700A. I turned on the power(PVDD:18V) ,VDDB and DVDD is working. But when I trying to flash firmware by BPA software, It keeps showing error message "Connection error:Please make sure the device is connected and swithed on"

Could anyone please give me some advice on this.

960转350W的轴流电机，要做300转的逆风启动，我调整这几个参数最多能到270转逆风就不行了，而且有10%的概率启不来。然后再测50转的逆风，有30%的概率起不来，扇叶一直缓慢的转，也不停，不报警。现在不知道怎么调整了，求各位大佬解答一下，谢谢！

Hello,

I’m working on parameter programming process. Value in the picture below generate from MCEwizard.

I would like to know reference of value in the orange field where are come from.

Other value I reference from register description in Motion Control Engine - Software Reference Manual v1.34 document.

Best Regards

Hardwares and Softwares:

1. EVAL-M1-101TF 
2. EVAL-M1-IM535 
3. iMotion Solution Designer on Windows 11

Problem:

1. I have connected my EVAL-M1-101TF with the EVAL-M1-IM535 power board
2. I am also able to upload the firmware successfully from the "Programmer" tab
3. But when I try to configure the parameters in the "Config Wizard" tab, even with the default EVAL-M1-101TF + EVAL-M1-IM535 configuration with the recommended motor (USB motor(iMotion2go)) or any other motor, at the last stage it throws an error saying "Error: Out of range error in bottom layer" (Video attached)
4. The log output shows

Note: This problem happens whether the motor EVAL-M1-101TF board is connected  or not to the iMotion Solution Designer software.

 

Any kind of help to get unstuck from this situation will be highly appreciated.

 

Thank you

Hello,

We are developing a gate controller using Infineon Motor Control IC, we have a custom board that uses IM564-X6D and IMC102T-F064. 

The register MotorCurrent is not giving the current in RMS,in our custom board.

When i tested in the eval board it was giving the RMS current.

How can i solve this problem?

 

Attached is the MCEWizard Configuration.

 

Best Regards,

 

Paulo
