INVERTER FUNCTIONS
3.6.6 Operation mode and command source (Pr. 79, Pr. 338,
Pr. 339, Pr. 340)
In the following table, operation using the operation panel, parameter unit or RS-485
communication is abbreviated to PU operation.
Used to select the operation mode, operation command source and speed
command source of the inverter.
The inverter can be run from the operation panel or parameter unit or by RS-485
communication (PU operation), with external signals (external operation), and by
CC-Link communication (CC-Link operation).
The inverter is placed in the external operation mode at power-on (factory setting).
