  • When I set it to greater than 7KRPM，gMotorVars.SpeedQEP_krpm I can't go up，gMotorVars.Speed_krpm When the value is greater than 7KRPM, it is the maximum motor speed.

    Please identify the motor parameters and inertia by using lab02b and lab12a first, and increase the USER_MOTOR_MAX_CURRENT according to the spec. of the motor.

    And please make sure that the motor can run up to such mechanical speed without field weakening.

    Please provide more details if you have any further questions. Thanks!
