The PWM value starts at and goes to zero.Forum L6234 arduino

 

The L has two SENSE outputs, that enable measuring the voltage drop across resistors and acquiring the current from that.

This happens even when the motor is going slow, so I don't think it is a problem with the Arduino not polling the hall sensors fast enough.

 

L breakout board Connected to the arduino pins 910 and 11 you can use also pins 5 and 6.

 

Necessary Necessary.

 

The next step is to calculate the position of the camera using an IMU and correct its position.

 

Commutation requires knowledge of the rotor position so that the right windings are energised.

 

Sorry for reviving this thread but I was also investigating the proper usage of these two weird sense pins.

 

Now I can turn it to a certain position with a potentiometer.

 

You need to sense position to commutate a brushless motor, whether by hall sensors or backEMF sensing, or some other method like periodically measuring winding inductance.

At this point the IN pin switches from 0 to 1 if the graph is increasing, otherwise from 1 to 0.Forum L6234 arduino

 

If You connect L INputs directly to Arduino and OUTputs to low impedance motor — current from Arduino pins will be driven directly through L to the windings and to the ground without external Vs power applied to L

 

Optionally if your encoder has index signal you can connect it to any available pin, figure shows pin 4.

 

forum? The chip clearly cannot handle the case where an arbitrary two phases are switched to ground and then measure the current separately for each

 

If I wanted to make the motor spin, I'd agree with you, but since I only need do adjust the angle it's different.

 

No hall and shaft encoders are used.

 

forum? The other two phases are simply the first phase shifted by 85 and steps, respectively.

 

Additionally I have swapped out motors and rebuilt the circuit but the same problem seems to happen.

Servo motor operation requires PWM to provide a linearly controlled torque as output of the PID loop - as I said its quite complicated as you'll be using the position information both for commutation and for calculating the input error value into the PID loop.
