Selection of operation mode and
operation location

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 between operation using external command signals (external operation), operation
from the PU (FR-DU07/FR-PU04/FR-PU07), combined operation of PU operation and external operation (external/PU
combined operation, and network operation (when RS-485 terminals or a communication option is used).
Parameter Number
79
Operation mode selection
The above parameters can be changed during a stop in any operation mode.
POINT
• Use the easy setting mode to set Pr. 79 in simple steps. (Refer to page 62)

Switchover mode
6
Switch among PU operation, External operating, and NET operation while keeping the
same operating status.
External operation mode (PU operation interlock)
X12 signal ON: Operation mode can be switched to the PU operation mode.
7
(output stop during External operation)
X12 signal OFF: Operation mode cannot be switched to the PU operation mode.
*1
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.
*2
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".
REMARKS
If switching of the operation mode is invalid even though Pr. 79 is set, refer to 5.5.9 Operation mode is not changed properly (page 327).
