Part Number:DRV8308
Hi everybody,
I am working with a DRV8308 and i have achieved to make it work quite well, but still want to solve an issue which happens at low speeds.
I am controlling a motor which is inside a mechanic reductive thing and this mechanic thing is coupled to a load. This load is 100N of resistive torque, right?
When the motor tries to move, it does but it must do at more than 250rpm otherwise it starts moving but only during a few seconds (less than a turn).
Please how can i adjust or tune the registers so i can make it work at 200rpm?
The registers setting is:
0x00-------24577
0x01-------1
0x02-------1204
0x03-------57218
0x04-------687
0x05-------12289
0x06-------33168
0x07-------300
0x08-------200
0x09-------500
0x0A-------62040
0x0B-------3500
By the way i am not sure what is the importance of the poles and zeros. Can anybody explain it a litte bit?
Thanks and best regards
