Part Number: DRV8434AEVM Other Parts Discussed in Thread: DRV8434SEVM Tool/software: Hi,
After intallation of the DRV8434SEVM GUI I got the following message:
What could be the reason, please advise!
Thank you!
Hi Mats,
Thanks for the update. The current waveform looks good.
Mats Webjörn said: so still no explanation why nFAULT and STL_REP immediately goes low when nSLEEP goes high.
The issue may be the high DCR of the motor coils 50 Ω. I think the torque count…
Part Number: DRV8434AEVM Tool/software: Hi team,
I want to test Stall Detection. The following flow was executed. -Obtain a specific voltage in Learning mode -Turn unloaded motor in Torque count mode
In this case, the voltage obtained in the Lerning mode…

Tool/software:
Hi team,
In my condition, EVM is not identified by GUI. What is the cause of this?
BTW, this matter occur in case of DRV84xx GUI too.
The port is not identified.
LED is blinking
Best regards, Goto
Hi Wang,
wang sky said: My stepper motor is rotating 15 degrees on one pulse, why is there a 45 electrical angle?
Thank you for this question. Electrical angle is the phase angle of the current waveform. See below representation. Square wave shown for…
Hi Roy,
The "Clear" button issues an nSLEEP reset pulse as described in the datasheet.
Roy Chou1 said: When motor did the returning to zero action, we used the STALL signal to let MCU know the motor was back to point of original.
Could you please…

Part Number: DRV8434AEVM Other Parts Discussed in Thread: MSP430F2617 , DRV8434A Dear TI-
I have installed the DRV8434AEVM. The evaluation board is working great! I really like the GUI; it's well-thought-out and easy to use.
I am looking for a copy…
