Selection of operation mode and operation location Parameter
6 - 172
6.17 Selection of operation mode and operation location
6.17.1 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 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 RS485 communication is used).
The above parameter 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".

Fixed to external operation mode
Operation can be performed by switching
between external and NET operation
mode
3
Combined operation mode 1
Running frequency:
Operation panel, and PU (FR-PU04/
FR-PU07) setting or external signal input
[multi-speed setting, across terminals
4-5 (valid when AU signal turns on)]
Start signal:
External signal input (terminal STF, STR)
4
External/PU combined operation mode 2
Running frequency:
External signal input (terminal 2, 4, JOG,
multi-speed setting, etc.)
Start signal:
Enter from the RUN key of the operation
panel and the FWD/REV keys of the PU
(FR-PU04/FR-PU07)
6
Switchover mode
Switchover between PU operation, exter-
nal operation, and NET operation is avail-
able while keeping the same operation
status.
7
External operation mode (PU operation
interlock)
X12 signal ON:
Operation mode can be shifted to PU
operation mode (output stop during
external operation)
X12 signal OFF:
Operation mode can not be switched to
PU operation mode.
