2.10 Operation Selection Function Parameters

2.10.1 Retry function

When any protective function (major fault) is activated and the inverter stops its output, the inverter itself resets automatically and performs retries. You can select whether retry is made or not, alarms reset for retry, number of retries made, and waiting time.

Parameter	Name	Factory	Setting	Remarks
		Setting	Range
66	Retry selection	0	0 to 3
	Number of		0, 1 to
67	retries at alarm	0	10, 101
	occurrence		to 110	Setting is enabled when Pr. 30 = "1"
68	Retry waiting	1s	0.1 to
	time		360s
69	Retry count	0	0
	display erase

<Setting>

Use Pr. 66 to choose the protective functions (major failures) for retries.

* Indicates the retry items selected. (OCT denotes any of OC1 to OC3 and OVT any of OV1 to OV3.)

Use Pr. 67 to set the number of retries at alarm occurrence.

Pr. 67 Setting	Number of Retries		Alarm Signal Output
0	Retry is not made.		———
1 to 10		1 to 10 times	Not output every time *
101 to 110		1 to 10 times	Output every time
* If the retry count is exceeded, "		" (retry count excess) is displayed.

Use Pr. 68 to set the waiting time from when an inverter alarm occurs until a restart in the range 0.1 to 360s.

Reading the Pr. 69 value provides the cumulative number of successful restart times made by retry. The setting of "0" erases the cumulative number of times.
