Dual Monitoring (D050,B160,B161); Trip Counter (D080) - Hitachi NES1-004SB Quick Reference Manual

Chapter 7 Explanation of Functions
7.1.14 Dual monitoring
Displays two different data configured in  and .

(*1) Excluding a Trip monitor 1 to 6(d081 to d086).
Note) If it enable the Frequency set in monitoring(=), () and () can change the output frequency as per
△▽ key in driving. But () can not chang () and ().
7.1.15 Trip Counter
When the trip counter function (d080) is selected, the inverter displays the number of times the inverter has
tripped.
(Display)
0. to 9999. in units of 1 trip
1000 to 6553 in units of 10 trips
7.1.16 Trip monitoring 1 to 6
When the trip monitoring function (d081 to d086) is selected, the inverter displays the trip history data. The
last six protective trips the inverter made can be displayed.
Select the trip monitoring 1 (d081) to display the data on the most recent trip.
(Display contents)
1) Factor of tripping (one of E01 to E41) (*1)
2) Output frequency at tripping (Hz)
3) Output current at tripping (A) (*2)
4) Main circuit DC voltage at tripping (V) (*3)
5) Cumulative inverter-running time until tripping (h)
6) Cumulative inverter power-on time until tripping (h)
*1 See Chapter 9.
*2 When the inverter status is in stop mode as a trip history, monitored value can be zero.
*3 When grounding fault is detected at power on, monitored value can be zero.
