Operation selection function 2 (Pr. 65 to Pr. 79)
<Setting>
In the following table, operation from the control panel or parameter unit is abbreviated to PU operation.
(1) Switchover mode
PU operation, external operation and computer link operation (when used with the communication option) can be
used by switching between them.

0
At power on, the external operation mode is selected. You can change between the PU operation mode and
external operation mode from the control panel ( ) or parameter unit ( / ). Refer to the fields of
settings 1 and 2 for the corresponding modes.

X16 signal OFF ....Switched to PU operation mode
REMARKS
• A stop function (PU stop selection) by of the PU (FR-DU04-1/FR-PU04V) is made valid during the operation
other than the PU operation mode. (Refer to page 115)
• Either "3" or "4" may be set to select the PU/external combined operation, and these settings differ in starting method.
Refer to page 128 for the computer link operation mode.
Operation Mode Switching Switching Operation/Operating Status
External operation to PU operation
1) Change the operation mode to the PU operation mode from the control panel or
parameter unit.
• Rotation direction is the same as that of external operation.
• Set speed is as set by the potentiometer (speed setting potentiometer). (Note that
the setting will disappear when power is switched off or the inverter is reset.)
External operation to computer link
operation
1) Mode change command to computer link mode is transmitted from the computer.
• Rotation direction is the same as that of external operation.
• Set speed is as set by the potentiometer (speed setting potentiometer). (Note that
the setting will disappear when power is switched off or the inverter is reset.)
PU operation to external operation
1) Press the external operation key of the parameter unit.
• Rotation direction is determined by the external operation input signal.
• Set speed is determined by the external speed setting signal.
PU operation to computer link
operation
1) Mode change command to computer link mode is transmitted from the computer.
• Rotation direction and set speed are the same as those of PU operation.
Computer link operation to external
operation
1) Command to change to external mode is transmitted from the computer.
• Rotation direction is determined by the external operation input signal.
• Set speed is determined by the external speed setting signal.
Computer link operation to PU
operation
1) Select the PU operation mode with the control panel or parameter unit.
• Rotation direction and set speed are the same as those of computer link operation.
