Chapter 4 Explanation of Functions
4.1.19 Life-check monitoring
d022: Life-check monitoring
Related code
When the life-check monitoring function (d022) is selected, the inverter
displays the operating life status of two inverter parts output from
corresponding intelligent output terminals by using LED segments of the
monitor.
The two targets of life-check monitoring are:
Life check
Normal
1: Life of the capacitor on the main circuit board
2: Degradation of cooling fan speed
Note 1: The inverter estimates the capacitor life every 10 minutes. If you turn the inverter power on and off
repeatedly at intervals of less than 10 minutes, the capacitor life cannot be checked correctly.
1 2
Note 2: If you have specified "01" for the selection of cooling fan operation (function "b0092"), the inverter
determines the cooling fan speed to be normal while the cooling fan is stopped.
4.1.20 Program counter display (easy sequence function)
d023: Program counter
Related code
While the easy sequence function is operating, the inverter displays the
program line number that is being executed.
For details, refer to the “Programming Software EzSQ” manual.
4.1.21 Program number monitoring (easy sequence function)
d024: Program number monitoring
Related code
When the program number monitoring function (d024) is selected, the
inverter displays the program number of the downloaded easy sequence
program.
Note that you must describe a program number in the program you create. For details, refer to the
“Programming Software EzSQ” manual.

4.1.26 Trip Counter
d080: Trip Counter
Related code
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
