MCT8329A: BLDC motor cannot reach maximum speed at no load.

Part Number: MCT8329A

Hi person in charge,

I want to control two types of motors with the same motor controller in which MCT8329A is implemented. I am trying to operate the following two types of motors. Motor 1 can operate at maximum speed with no load, but Motor 2 could not operate at maximum speed with no load. I am attaching the parameters, but I tried to increase the ILIMIT a little, but it could not reach the maximum speed, probably because it was no load.
Please advise if you can guess what the cause is.
