Select this code to ‘Yes’ when using MMCfunction without PID control. The frequency isdetermined by real value of control amount instead PIDcontroller output. The real value is also used as theStart/Stop reference of Aux. motors.The following figure shows the running pattern with thisfunction applied for controlling the flow rate of a tank. Tocontrol the flow rate according to the water level of atank, divide the water level of the tank into the region tothe number of Aux. motors plus one, and map eachregion from staring frequency to maximum frequency.The inverter increases output frequency to lower thewater level in the tank when the water level in the tankrises. When reaching maximum frequency, inverter148
