(1) Operation mode basics
(2) Operation mode switching method
⋅ The operation mode specifies the source of the start
command and the frequency command for 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 186.)
REMARKS
⋅ For switching of operation by external terminals, refer to the following:
