DRV10983: BEMF Abnormal error

Hey na na78,

Sorry for the delay. Can you explain "increasing rotation speed" a bit more? Does this occur when the motor is increasing to its target speed? Or can they reach a target speed but trigger the error when a higher speed is entered?

• If this occurs when the motor is increasing to its target speed, then the programmed Kt of the motor the customer is spinning might not be correct and must be verified.
  • Please refer to this other thread with instructions for measuring Kt
• If this occurs when trying to enter in a higher speed

• • Please disable the fault by unchecking the box on the advanced settings tab in the faults section. Monitor the faults again and see if another fault is triggered.
  • If no fault is triggered, please manually and gradually increased the programmed Kt on the basic settings tab in the motor paramters section. If the motor is able to achieve higher speeds after increasing the Kt manually, use the new Kt value.

Hope this helps,

-Cole
