Selection of operation mode and operation location
4.23 Selection of operation mode and operation location
4.23.1 Operation mode selection (Pr. 79)
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".

Used to select the operation mode of the inverter.
Mode can be changed as desired between operation using external signals (external operation), operation from
the PU (FR-DU07/FR-PU07/FR-PU04), 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).

Use external/PU switchover mode (
) to switch
between the PU and external operation mode.
At power on, the inverter is placed in the external
operation mode.

Fixed to external operation mode
Operation can be performed by switching between the
external and Net operation mode.
