"D" Group: Monitoring Functions
3-3-26 Fault Frequency Monitor [d080]
3-3-27 Fault Monitors 1 to 6 [d081 to d086]
3-3-28 Warning Monitor [d090]
3-3-29 DC Voltage Monitor [d102]
Displays the number of times the inverter has tripped.
This number is saved in the EEPROM when the power is turned off.

d080

Fault frequency monitor

Displays the records of the last 6 errors. Error records are saved in the
EEPROM when the power is turned off.
The record of the latest error is displayed under Fault Monitor 1 (d081).
(Display)
(1) Cause of trip (One of E01 to E83 is displayed.)
(2) Output frequency [Hz] at the time of tripping.
(3) Output current [A] at the time of tripping. If the inverter is currently stopped
(E**.1), the monitor value may become zero.
(4) P-N DC voltage [V] in the main circuit at the time of tripping. If tripping
occurs due to ground fault at power-on, the monitor value may become
zero.
(5) Total inverter RUN time [h] before the trip.
(6) Total inverter power ON time [h] before the trip.
(1) Trip factor
d081 E07.2
is shown if no trip has occurred.

If the set data is inconsistent with other data, a warning is displayed.
While a warning is present, the Program LED (PRG) indicator remains lit until
the data is corrected.
The inverter P-N DC voltage (DC voltage between the inverter terminals P/+2
and N/-) is displayed.
During operation, the monitor value changes depending on the actual DC
voltage of the inverter.
