 Set the terminal among Multi-function input terminals (P1~ P5) for second motor operation.
 To define the terminal P5 as second motor operation, set I21 to 12 in the I/O group.

Used when an inverter operates 2 motors connected to two different types of the loads.

2nd motor operation does not drive 2 motors at the same time.

As the figure below, when using two motors with an inverter by exchanging them, select one motor
from 2 motors connected. When 1
st
selected motor operation is stopped, select a terminal for 2nd motor
and define H81-H90 parameters to drive the 2nd motor.
 Define the 2nd motor select when a motor is stopped.
 H81 ~ H90 parameters function the same as 1
st
motor.
