5. PARAMETERS
5.6 (D) Operation command and frequency command
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).
The following table lists valid and invalid commands in each operation mode.
*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".
