(2) Operation mode switching method
The operation mode is to specify the source of
inputting the start command and frequency
command of the inverter.
Basically, there are following operation modes.
External operation mode: For inputting start
command and frequency command by an external
potentiometer and switches which are connected
to the control circuit terminal.
PU operation mode: For inputting start command
and frequency command by operation panel (FR-
DU07), parameter unit (FR-PU04/FR-PU07) and
RS-485 communication with PU connector.
Network operation mode (NET operation
mode): For inputting start command and
frequency command by RS-485 terminal and
communication options.
The operation mode can be selected from the
operation panel or with the communication
instruction code.
REMARKS
Either "3" or "4" may be set to select the PU/external combined operation, and these settings differ in starting method.
In the initial setting, the stop function by of the PU (FR-DU07/FR-PU07) (PU stop selection) is valid also in other than the
PU operation mode. (Pr. 75 Reset selection/disconnected PU detection/PU stop selection. Refer to page 305.)
