Hi Murugavel,
I used DRV8889-Q1 to drive the 14HK0405 stepping motor, and found an issue. The test conditions were as following:
Decay mode: Smart Tune Ripple Control
When the motor stopped, sometimes I could feel the motor slightly vibrated(not rotate exactly), and existed until
(1)the motor was started again, or
(2)change the decay mode to other modes, or
(3)changed the torque DAC to other values(higher values such as 62.5%, or lower values such as 18.75%).
It seemed to be related to the current change related to Smart Tune Ripple Control, what exactly is this issue and what is the reason?
Thanks,
Alex
