Hi,
I am using a DRV8031-HC-EMV Rev D Kit with the F2806M controlCARD and a BLDC-motor (Faulhaber 4490 H 024 BS). The characteristics of the motor are 1 pair of poles, 24V and a maximum speed of 5450 rpm. I work with the example programs MotorWare_1_01_00_12.
I have different problems:
- The motor reaches only the half maximum speed. If the SPEEDREF is set to 5 krpm in lab2a the motor has 2.24 krpm.
-The second problem is the motor don’t change the direction in lab2b and the next labs. In lab2a if I set the SPEEDREF negative the motor change the direction. But in lab2b the motor stops if the SPEEDREF is negative.
I think it is a problem with the parameters?
Thanks in advance
Regards,
Christoph
