The 1st functions are applied if the assigned
multifunction terminal is not defined as ‘2nd Func’
nor ON. The 2nd function parameters are applied
when the multifunction input terminal set to ‘2nd
Func’ is ON. Parameters not listed on the table above
are same as the 1st function.

the motor is stopped. Over voltage or over current
fault may occur when the motor is exchanged during
operation.

These functions APP-30 ~ APP-39 are displayed only
when one of the multifunction inputs in codes I/O-20
to I/O-27 is set at ‘2nd func’.
When an inverter is controlling two motors by
exchanging, different values can be set for the 2nd
motor by using the multifunction input terminal.
Following a cross reference table shows the 2nd
functions corresponding to the 1st functions.
Description
Note: The ‘User V/F’ function of FU1-40 [V/F

motor.

This code shows how many auxiliary motors are run
by MMC control.
[MMC]: The ‘PID’ control should be selected in
APP-02 to use this function.
 One inverter can control multiple motors. This
function is often used when controlling the rate and
pressure of flow in fans or pumps. Built-in PI
controller controlsa main motor after receiving
process control feedback value and keeps the control
value constant by connecting auxiliary motors to
commercial line when needed.
