Startup failure without mechanical load

[RReic.2]

Hello,

we are using Sensorless FOC with open loop starting of the BLDC motor. The Motor is starting reliably under normal and heavy load conditions. But without load the I got startup failure. Any idea what paramter should be checked or improved?
