Selection of control source
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).

selection
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".
