I’m testing a BLDC,AC 230V in, 2HP, 8 poles,2850RPM rated,application in water pumper. hardware referenct HVKIT. use mcu 28027F.
motorware version: motorware_1_01_00_14
ccs Version: 6.0.1.00040.
the following figure is an abnormal wave. in the cause of the water pumper acceleration. use lab09.

what happend at that moment??? Many tests are like this. The pump is normal, there is no block.
