F526 error with an AKM11B AKYNR

I have an error F526 (and F531) as soon as I try to rotate a AKM11B motor which is new...I have checked cable and motor phases : everything is OK

Is there any parameter in the AKD drive to setup for the threshold of this short circuit error?

As it is a very small motor (AKM11), I know that something the tuning is more difficult because of small inertia, but in my case, no load is attached on the motor.

Best regards.

I recommend you check the motor’s resistance from phase to phase, the AKM11B resistance should be around 18.23 ohms. The motor’s resistance from ground to a phase should be in the megaohms.

At the motor connector A pin is the U Phase, C pin is the V phase and B pin is the W phase and PE is ground.

 

Thanks for your answer.

 

I measure 10.6 ohms between U and V, 10.6 ohms between U and W, and 2.1 ohms between V and W....

 

So definitely, I think that the motor has a problem !!!
