DRV8305-Q1EVM: Motor speed not going more than 1325 RPM

Part Number: DRV8305-Q1EVM
Other Parts Discussed in Thread: MOTORWARE


We have started the InstaSpin FOC with a BLDC motor. Now once we put the speed reference as 1500 RPM, the motor reaches to 1325 rpm and remains on that speed, even after giving higher reference speed. I have changed the parameter value of USER_MOTOR_MAX_CURRENT  to (20.0) and USER_MOTOR_FLUX_EST_FREQ_Hz (100.0) in user.h file. Still the motor speed is not reaching more than 1325 RPM. Can u please suggest which parameter to change to increase the speed?
