Selection of operation mode and
operation location
4.19 Selection of operation mode and operation location
4.19.1 Operation mode selection (Pr. 79)
The above parameters can be changed during a stop in any 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".

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).

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).
