Part Number: DRV8307
Hi,
I'm beginner for motor driver, and have a problem with using TI's DRV8307
The symptom is as below.
-> when repeat start and stop in turn, discover the symptom that do not start.
: The motor emits a high requencty sound.(in a view of the step motor, it seems out of phase.)
Opeatation sequence :
ON sequence : ENABLE On -> PWM operate 1% ~ 100% 1ms period 1% step.
OFF sequence : 1% ~ 100% 1ms period 1% step ENABLE Off
What do you think the root cause is?
Hall Position recognition failure?
Incorrect operating procedure when driving motor?
Regards,
TS
