Other Parts Discussed in Thread: DRV10866 Hi,
My customer is using DRV10866. He has a issue about Starting position of FG output. He uses FG signal to confirm position motor. and he say that "DRV10866 has 3 point of starting(occurring) position of FG signal…
Other Parts Discussed in Thread: DRV10866 Hi, I have a question about DRV10866 Bemf count at start up operation. In datasheet, There is the following words. “Once motor reaches to sufficient speed to allow four consecutive successful back-emf zero-crossing…
Other Parts Discussed in Thread: DRV10866EVM , DRV10866 Hi My customer is using DRV10866EVM. He uses motor whose pole pairs is 4.
He has a issue. When motor speed is high, FG waveform is missing teeth. I think it exceeds RPM spec on which DRV10866 can…
Other Parts Discussed in Thread: DRV10866EVM , DRV10866 Hi My customer is using DRV10866EVM. He uses motor whose pole pairs is 4. He sets FGS=1. Could you let me know how to calculate max RPM value? He has a issue. When FG frequency exceeds 700Hz, Motor…
Other Parts Discussed in Thread: DRV10866EVM After I failed to run with 10963,
I got new motor with WYE connection.
Then motor turned a little then stop for couple of second run again - stops.
I checked signal out with oscilloscope.
I see 3 frequency…

Part Number: DRV10964 Other Parts Discussed in Thread: DRV10866 , Hello Team,
we do have the goal to set the motor speed n = 40Hz. With DRV10866 we adjust PWM duty cycle as long we measure 240Hz at FG pin.
FGS pin is grounded. pole pairs of motor = 6…
I was assuming that the open loop portion of the starting sequence would obviate the need for external ramping up of motor speed by ramping the frequency of the PWM.
As I said earlier, one of my goals was to eliminate the resistor parts to simulate a…
Part Number: DRV10866EVM Other Parts Discussed in Thread: DRV10866 Hi,
I am using the DRV10866 in a closed loop application. The current limit resistor is the default 3.8k. With a light inertia the motor starts up quickly and robustly. With a higher inertia…
