Hello,

I have a HBL1650. I tried to use the analog mode to command a three phase motor. From the user manuel, I understand that by supplying 2.5V to 5V to the analog input of the controller the motor will turn in the positive direction and from 0V to 2.5V the motor will turn in the negative direction. I tested this mode when the USB cable is plugged into the controller and on the Roborun mode I saw that the analog lamp had turn red.

I got a problem which is when I unplugged the USB cable of the controller that is connected to PC Roborun, the motor will start turning even though I was supplying 2.5V.

Why is this so? Must I command the motor with USB connection even though in analog mode?

Likely you have a settings issue or there is noise on the analog input.
