failed at motor parameters measurement

Motorbench is a very nice tool after I watched all the video.
My project based on an1078 and it work when motor spin free or light load. but it stop when motor under negative load, I have connected a load resistor when motor voltage higher than 80V. 
I believe the PI parameter is not good and try to tune PI loops. Try to use Motorbench do that job. But I can't get those parameter in motor configuration under Motorbench. and I don't full understand all of them, like Ld, Lqm B Tf and J. I tried to measure them and it never passed, always failed at Ke measurement, and report the load is not constant. Even if I changed a motor and get the similar issue. I have read the motorbench release notes and can't make it work.
Have sent email to motor bench [email=motorbench-support@microchip.com]motorbench-support@microchip.com[/email]. But not feed back.
Not sure where to get help.
