Problems with the X-NUCLEO-IHM07M1

[UNBEEKANNT]

Hello everybody,

I have a Problem with the X-NUCLEO-IHM07M1 power board . I am using it with the Nucleo-F401RE.

My setup :

Software: Cube IDE + ST Motor control workbench 5.4.8 (I have also tried it with V. 6.2.0)

Motor: Maxon EC i 30 , Art. No 539477 (24V , 2 pole pairs, Hall Sensors)

With the power board X-NUCLEO-IHM08M1 it works . Same setup and software. 

For me it is a little bit confusing because X-NUCLEO-IHM08M1 power board is for bigger motors than the Maxon Motor and in my opinion it should work better with the X-NUCLEO-IHM07M1.

If anyone has any ideas about this problem or needs further informations, please let me know.

Here is a screenshot from the motor data sheet.

Hello @UNBEEKANNT,

What kind of issue are you facing with X-NUCLEO-IHM07M1?
You mentioned "Same setup and software"; as IHM07 and IHM08 are differents, you should re-generate a project for each power board.

Hello @GMA ,

I meant with same software , the same programs(Workbench, motor profiler, cube ide) and same versions of them.

I have two different projects. One for each power board. When using the IHM08 power board, I observed short peaks in the input current, reaching up to 3.5 A(You can see it in the picture below). I have also a voltage drop at the DIA/EN Input of the IC L6230PD, which is used for the board IHM07. 

But this signal is never used in the code for the board.

Voltage drop of the DIA/EN Signal measured at PIN CN10/13

 

Input current for the motor. 100mV = 1 A(Board IHM 07)

Input current for the motor. 100mV = 1 A(Board IHM 08)

I have tried it with and without Hall Sensors,different PWM Frequency ( 5000-25kHz), but nothing works.

If you have any ideas or you need further informations, please let me know.

Thank you for your help.

 

best regards

Hello @UNBEEKANNT,

My question about "issue" was more, with IHM07, do you have a reported error? Does the motor spins?
