APP-18: Stop Frequency of Aux. Motor 4
The inverter turns off RLY3, RLY2, RLY1, and AUX in
order if the output frequency is below the frequencies set
in APP-15 to APP-18, respectively, and the time is over
APP-20.
APP-19: Delay Time before Operating Aux.

APP-20: Delay Time before Stopping Aux. Motor
Sets the time the inverter waits before starting the
auxiliary motors.
Sets the time the inverter waits before stopping the
auxiliary motors.
[Aux. Motor Start/Stop with MMC]
APP-21: The Number of Aux. Motors
Sets the number of auxiliary motors connected to the
inverter.
APP-22: PID Bypass Selection
This is used to bypass the PID operation selected in
FU2-47. Select this code to ‘Yes’ when using MMC
function without PID control. The frequency is
determined by real value of control amount instead PID
controller output. The real value is also used as the
Start/Stop reference of Aux. motors.
The following figure shows the running pattern with this
function applied for controlling the flow rate of a tank. To
control the flow rate according to the water level of a
tank, divide the water level of the tank into the region to
the number of Aux. motors plus one, and map each
region from staring frequency to maximum frequency.
The inverter increases output frequency to lower the
water level in the tank when the water level in the tank
rises. When reaching maximum frequency, inverter
