!
You can select whether write to various parameters can be performed or not. Use this function to prevent parameter
values from being rewritten by misoperation.
!
The inverter operation mode can be changed as desired between operation using external signals (external
operation), operation from the PU (FR-DU04
-1
/FR-PU04V), combined operation of PU operation and external
operation (external/PU combined operation), and computer link operation (when the FR-A5NR option is used).
Refer to the Instruction Manual (detailed) for details.
Refer to page 46 for details.
Pr. 77 "parameter write disable selection"
Setting Description
0
Parameter write can be performed. (Write is enabled only during a
stop in the PU operation mode.)
1
Parameter write cannot be performed. (Write to Pr. 22, Pr. 75, Pr. 77
and Pr. 79 "operation mode selection" is enabled.)
2 Write during operation is enabled.

Pr. 79 "operation mode selection"
Pr. 79 Setting Function
0
At power-on, the inverter is in the external operation mode.
Operation can be performed by switching between PU and external operation.
1 PU operation mode
2 External operation mode
3
External/PU
combined
operation mode 1
Speed command Start command
Set from the PU (FR-DU04
-1
/FR-PU04V)
(direct setting, ) or external
signal input (multi-speed setting only)
External signal input (terminal STF, STR)
4
External/PU
combined
operation mode 2
Speed command Start command
External signal input (terminal 2, 1, jog,
multi-speed selection)
Input from the PU (FR-DU04-1
/FR-PU04V)
(start command using , )
6
Switch-over mode
Switch-over between PU operation, and external operation, and computer link operation (when the
FR-A5NR or any other communication option is used) can be done while running.
7
External operation mode (PU operation interlock)
X12 signal ON ....... May be switched to PU operation mode (output stop during external operation)
X12 signal OFF...... Switching to PU operation mode inhibited
8
Operation mode switching by the external signal (disallowed during operation)
X16 signal ON ....... Switched to external operation mode
X16 signal OFF...... Switched to PU operation mode
