Problem to Reach Rated Speed

Hello everbody,

I am using the KMS v1.2 with a FRDM-KV31 for a current control project. After the KMS v1.2 was released I started to use the sensorless control with hall startup and indeed the startup torque control is much better. However, it does not reach the rated speed of 1050 rom and its maximum is around 480 rpm. I have tested another project without the hall startup and it does reach the rated speed with the same current requested.
What is a possible workaroud for this issue?

Thanks in advance
