DRV10983-Q1: Can't control speed, spin from stop to max then repeat

wenjun sun

Part Number: DRV10983-Q1

So I made my board according to the eval board. Without doing any configuration, my motor spins from stop to max speed and stop for few seconds and repeat. Any idea?

Hey wenjun,

It sounds like you motor profile needs to be tuned a bit. To start, the DRV10983-Q1 needs the Phase Motor Resistance and Motor Torque Constant (Kt). To measure these, please refer to section 2.2 and 2.3 the DRV10983-Q1 Tuning guide if you need help.

Then, feel free to use some default settings provided below through the use of the GUI or the appropiate registers. Be sure to add in the appropiate values that you found for the Phase Resistance and Kt.

This should get the motor spinning and allow you to start tuning. If the motor continues to stop, please monitor the faults that are shown on the display tab and report back which fault is triggering.

Best,

-Cole
