Hi Team,
My customer evaluates DRV8828EVM and have a question.
He set the GUI to values shown and repeated the following sequence(1→2→1→2・・・), he found sometimes stepping motor didn't reach "Desired Speed PPS" and then stayed "Start Speed PPS".
The recall factor of this behavior is about 60%.(12 times out of 20)
1) select "Start Steps"
2) select "Stepping"
When this issue occured, to select "UpdateSpeed" help him to to reach desired speed.
He found the waveform of Phase pin that is input from MSP430 is different from normal one and this issue also occures even if motor isn't connected to DRV8828EVM.
Is it possible case of DRV8828EVM?
Best Regards,
Yaita/ Japan disty
