Hello,

I am trying to command a Sonceboz 5612 three phase dc brushless motor(12V nominal voltage and 60A max current) using HBL 1650. I have got some problems. The motor can't seems to turn in both direction. It turns in the positive direction but not the reverse. Everytime I slide the slider to the reverse direction, the stall light turns on. Sometimes on the positive direction the stall light turns on too, mostly when I slide just a little. If I slide a lot such that the a high value is indicated in the command box, the motor will turn.

Can someone explain to me what is going on please?

Incorrect UVW wire phase connections. Even if your motor is labeled UVW by the manufacturer, it does not always mean that it is the UVW matching with our controllers. Please refer to video that explains all this.

Ok thanks alot! Yes it is the problem of wiring. I corrected the UVW wiring error between the controller and the motor and now the motor can turn in both direction in open loop mode.

I have got another question actually. I tried to command the motor in closed loop speed mode by sliding the slider -10 to the left but the motor keeps rotating back and forth in a quick manner. And I saw that in the Motor Command box the value keep alternating between 1000 and -1000. The graph shows an alternating signal but not really periodic.

Can someone explain to me what is going on here? Isn't the closed loop speed mode suppose to drive the motor to the desired speed, so the motor should be rotating just like in open loop mode?

This is very likely a PID issue in your closed loop parameters. Make sure that your feedback sensor in your motor configuration setting is set to hall sensor if you are not using encoders.

Start with the following.
P=0
I=2
D=0

Loop error detection disabled.

Add more I gain as needed so that the motor gets as close as it can to desired speed without over shoot and undershoot. Then add small amounts of P gain as needed if the desired speed is not reached (Decimal values).
