4.1.19 Life-check monitoring

Related code

When the life-check monitoring function (d002) 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:

1: Life of the capacitor on the main circuit board

2: Degradation of cooling fan speed

d022: Life-check monitoring

Life check

Normal

2 1

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.

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)

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)

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.

4.1.22 User Monitors 0 to 2 (easy sequence function)

d025: user monitor 0

d026: user monitor 1

d027: user monitor 2

The user monitor function allows you to monitor the results of operations in an easy sequence program. For details, refer to the Programming Software EzSQ Instruction Manual.

4.1.23 Pulse counter monitor	Related code

4.1.24 Position command monitor (in absolute position control mode) Related code

The user monitor function allows you to monitor the results of operations	d028: Pulse counter monitor
in an easy sequence program.
For details, refer to the Programming Software EzSQ Instruction Manual.

4.1.25 Current position monitor (in absolute position control mode)

The current position monitor function allows you to monitor the current position in absolute position control mode.

For details, see Section 4.3.12.

4.1.26 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
