Hi,
I run the motor in "drv8835 Fast DK Mode".
The following waveform appears on the oscilloscope.
When the pulse is low, about 6~7V is output
Is it working correctly?
Is it normal not to fall to 0V?
When operating in Slow DK (phase / in mode), the motor will run slowly even with a small duty ratio.
However, when operating with Fast DK, the motor does not operate at a small duty ratio, and the motor operates only when the duty ratio has risen above a certain value.
Is it working right?
Do you have a guide or a workaround?
Thank you in advance for your reply.
Have a nice day.
