4.19 Selection of operation mode and operation location

Purpose
Operation mode selection
Started in Network operation mode
Selection of operation location

4.19.1 Operation mode selection (Pr. 79)

Used to select the operation mode of the inverter.
Mode can be changed as desired among operation using external command signals (External operation), operation
from the operation panel and PU (FR-PU07/FR-PU04) (PU operation), combined operation of PU operation and
External operation (External/PU combined operation), and Network operation (when RS-485 communication or a
communication option is used).

The above parameters can be changed during a stop in any operation mode.
∗ The priorities of the frequency commands when Pr. 79 = "3" are "Multi-speed operation (RL/RM/RH/REX) > PID control (X14) > terminal 4 analog input (AU)
> digital input from the operation panel".
