Part Number: DRV8825
I have some questions about DRV8825.
On the customer’s application, STEP frequency is changed during operation.
The current is distorted while low STEP frequency, but no problem while high STEP frequency.
To improve above, the decay mode need to be changed between mixed and fast.
Following current waveform shows same STEP frequency(500Hz) and different decay mode.
To change decay mode from mixed to fast, the current distortion will be disappear.
(1)Can I change decay mode between mixed and fast without RESET during operation?
(2) Can I change decay mode between mixed and fast with RESET during operation?
(3) Do you have suggested schematic for changing decay mode between mixed(DECAY=open) and fast(DECAY=high)?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
