Function list (Simple mode parameters)

Pr. 77 "parameter write disable selection"

!You can select whether write to various param eters can be perform ed or not. Use this function to prevent param eter values from being rewritten by m isoperation.

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.

REMARKS

•Parameters below are write-enabled during operation even when Pr. 77="0".

Pr. 79 "operation mode selection"

!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).

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.

1PU operation mode

2External operation mode

	External/PU	Speed command		Start command
3		Set from the PU (FR-DU04-1/FR-PU04V)
	combined	(direct setting,	) or external	External signal input (terminal STF, STR)
	operation mode 1
		signal input (multi-speed setting only)
	External/PU	Speed command		Start command
4		External signal input (terminal 2, 1, jog,		Input from the PU (FR-DU04-1/FR-PU04V)
	combined
	operation mode 2	multi-speed selection)		(start command using FWD , REV )

Switch-over mode

6Switch-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.

External operation mode (PU operation interlock)

7X12 signal ON ....... May be switched to PU operation mode (output stop during external operation) X12 signal OFF...... Switching to PU operation mode inhibited

Operation mode switching by the external signal (disallowed during operation)

8X16 signal ON ....... Switched to external operation mode

X16 signal OFF...... Switched to PU operation mode
