PRODUCTION DATA
MCT8329A supports three different kinds of profiles (linear, step, forward-reverse) to input control reference signal to enable a variety of end-user applications. The input control reference signal can be motor speed, DC input power or motor voltage (motor PWM duty cycle) as configured by CLOSED_LOOP_MODE and CONST_POWER_MODE. The different profiles can be configured through REF_PROFILE_CONFIG. When REF_PROFILE_CONFIG is set to 00b, the profiler is not applied and the input reference is same as the duty command as explained in GUID-7E9269D7-B231-4B47-9070-3BD7B0D231F5.html.
In speed control mode, the profiler output REF_X corresponds to percentage of Maximum Speed (configured by MAX_SPEED) as shown in Equation 6. In power control mode, the profiler output REF_X corresponds to percentage of Maximum Power (configured by MAX_POWER) as shown in Equation 7. In voltage control mode REF_X corresponds to the percentage of PWM duty cycle of applied voltage to the motor.
