Part Number: LAUNCHXL-F280025C
Other Parts Discussed in Thread: DRV8329
Tool/software:
I am trying to rotate my customer's motor using Universal Project Lab (level 3 incremental build), but the motor stops when I try to increase the speed.
I could increase the speed up to 200 but it stops if I try to increase it to 300.
It was observed that Iq value starts varying quite widely as the speed is increased. Please check the expression value of Iq (fback value) varying from 2 A to 4A, and also the oscilloscope reading.
Why such variation is occurring? Is it possible that the motor is stopping due to even more increase in Iq current variation on increasing the speed?
How can I run the motor at higher speed?
Supply voltage: 12V; Set-up: F280025C + DRV8329
