3.3.5 Reading maintenance information--"Maintenance Information"
Menu #5 "Maintenance information" in Programming mode contains information necessary for
performing maintenance on the inverter. Table 3.12 lists the maintenance information display items and
Figure 3.9 shows the status transition for maintenance information.
Table 3.12 Maintenance Display Items
LED monitor
shows:
Display contents Description
A
Accumulated run
time
Shows the accumulated power-ON time of the inverter.
Unit: thousands of hours. When the total ON-time is less than 10,000
hours (display: 0.001 to 9.999), it is possible to check data in hourly
units.
When the total time is 10,000 hours or more (display: 10.00 to 65.53),
the display will change to units of 10 hours. When the total time
exceeds 65,535 hours, the display will be reset to 0 and the count will
start again.
A
DC link bus
voltage
Shows the DC link bus voltage of the inverter.
Unit: V (volts)
A
Max. temperature
of heat sink
Shows the maximum temperature of the heat sink for every hour.
Unit: ºC
A
Max. effective
current
Shows the maximum effective current for every hour.
Unit: A (amperes)
A
Capacitance of the
DC link bus
capacitor
Shows the current capacitance of the DC link bus capacitor, based on
the capacitance when shipped as 100%. Refer to the FRENIC-Mini
Instruction Manual, Chapter 7 "MAINTENANCE AND
INSPECTION" for details.
Unit: %
A
Accumulated run
time of electrolytic
capacitor on the
printed circuit
board/s
Shows the accumulated run time of the capacitor mounted on the
printed circuit board/s.
The display method is the same as for "Accumulated run time" above.
However, when the total time exceeds 65,535 hours, the count stops
and the display remains at 65.53.
A
Accumulated run
time of the cooling
fan
Shows the accumulated run time of the cooling fan.
If the cooling fan ON/OFF control (function code H06) is effective,
the time when the fan is stopped is not counted.
The display method is the same as for "Accumulated run time" above.
However, when the total time exceeds 65,535 hours, the count stops
and the display remains at 65.53.
A
Number of startups The motor run times (the number of times the inverter run command
is set to ON) are calculated and displayed.
1.000 indicates 1,000 times. When any number ranging from 0.001 to
9.999 is displayed, the display increases by 0.001 per startup, and
when any number from 10.00 to 65.53 is displayed, the display
increases by 0.01 every 10 startups.
A
No. of RS-485
errors
Shows the total number of times RS-485 communications error has
occurred after the power is turned ON.
Once the number of errors exceeds 9.999, the display (count) returns
to 0.
A
RS-485 error
contents
Shows the latest error that has occurred with RS-485 communications
in hexadecimal format.
Refer to the RS-485 Communication User's Manual.
A
ROM version of
inverter
Shows the ROM version of the inverter as a 4-digit display.
A
ROM version of
keypad
Shows the ROM version of the keypad as a 4-digit display. (For
remote keypad only.)
