Selection of operation mode and operation location

4.18 Selection of operation mode and operation location

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

4.18.1 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 is used).

This parameter allows its setting to be changed in any operation mode even if "0 (initial value) or 1" is set in Pr. 77 Parameter write selection.
∗ 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".
