5.6.1 Operation mode selection
Select the operation mode of the inverter.
The mode can be changed among operations using external signals (External operation), operation by operation panel or the
parameter unit (PU operation), combined operation of PU operation and External operation (External/PU combined operation),
and Network operation (when RS-485 terminals or communication option is used).

79 Operation mode selection
D000
The following table lists valid and invalid commands in each operation mode.
Pr.79
setting
0 External/PU switchover mode.
(initial The inverter operation mode can be switched between PU and External by pressing
value)
.
At power ON, the inverter is in the External operation mode.
Operation mode
1 PU operation mode fixed
2 External operation mode
fixed.
The operation can be
performed by switching
between the External and
NET operation modes.
3 External/PU combined
operation mode 1
4 External/PU combined
operation mode 2
6 Switchover mode
Switching of PU, External, and NET operation modes can be performed during
operation.
7 External operation mode (PU operation interlock)
X12 signal ON: Switchover to PU operation mode enabled (during External operation,
output shutoff)
X12 signal OFF: Switchover to PU operation mode disabled
*1 The priority of frequency commands when Pr.79 = "3" is "multi-speed operation (RL/RM/RH/REX) > PID control (X14) > terminal 4 analog input
(AU) > digital input by operation panel".
