Signal U, V and W of HBL1650

I'm trying to generate signal U, V, W of HBL1650 without motor and I want to display it on my oscilloscope. I connect my connector of Hall sensor to HBL1650 (GND, +5V, A, B, C) and I provide the connector Hall sensor in 5V (GND, +5V). But I don't see anything on my oscilloscope. Or it is nessasry to connect A,B,C ?

I can't measure currents U, V, W of motor. In "nxtgen_controllers_userman", there is only current to measure : getvalue(_A, 1). It is a medium current or effective current of the 3 currents U, V, W ?

You must connect A B C also

getvalue(_A, 1) will return an estimation of the motor RMS current. It is computed by measuring the Battery current and dividing it by the PWM ratio.

You cannot know the individual U V and W current. These are AC currents

On this little card, I connect A, B, C, +5V et GND to my Hall sensor of motor.
And I must add a resistor 4.7K ohm and a capacitor 1nF between +5V and GND ?

No, just the wires is all you need. Take a look at the video tutorial on our home page regarding basic setup of a brushless motor controller.

Foremost, I connect my power supply to GND and Power Control. After, I disconnect my power supply to Power Control and connect it to Vmot ?

Because, I connect directly my power supply to Vmot, and I don't see anything on my oscilloscope

Did you give the controller a motor command?

I use only Ground and Vmot, I want to see output signal U, V, W via an oscilloscope without motor . In video tutorial, I see that first you connect power supply to Power Control
Because, with HDC2450, I connect my power supply to Ground and Vmot, and it works!
