Item Description
5_14
Inverter's ROM version
Shows the inverter's ROM version as a 4-digit code.
5_15
Inverter's ROM version
Sub CPU
Shows the inverter's Sub CPU ROM version as a 4-digit code.
(Only type of FRN0020E2-2 / FRN0012E2-4 /
FRN0011E2-7 or below)
5_16
Keypad's ROM version
Shows the keypad's ROM version as a 4-digit code.
5_17
Number of RS-485
communications errors
(COM port 2)
Shows the total number of errors that have occurred in RS-485
communication (COM port 2, connection to terminal block) after
the power is turned ON.
Once the count exceeds 9999, the counter will be reset to “0.”
5_18
Content of RS-485
communications error
(COM port 2)
Shows the latest error that has occurred in RS-485
communication (COM port 2, connection to terminal block) in
decimal.
For error contents, refer to the “RS-485 Communication User’s
Manual.”
5_19
Option's ROM version 1
Shows the ROM version of the option as a 4-digit code.
If the option has no ROM, “
----
” appears on the LED monitor.
5_23
Cumulative run time of motor 1
Shows the content of the cumulative power-ON time counter of
motor 1.
Counter range: 0 to 99,990 hours
Display range:
0
to
9999
(the x10 LED turns ON)
Actual cumulative motor run time (hours) =
Displayed value x 10
When the count exceeds 99,990, the counter will be reset to “0”
and start over again.
5_24
Temperature inside the
inverter
(real-time value)
Shows the current temperature inside the inverter.
Unit: °C
The internal temperature is not measured at inverters of
FRN0069E2■-2 / FRN0044E2■-4 / FRN0011E2■-7 or
below models, and therefore the temperature is not displayed.
5_25
Temperature of heat sink
(real-time value)
Shows the current temperature of the inverter heat sink.
Unit: °C
5_26
Lifetime of DC link bus
capacitor
(elapsed hours)
Shows the cumulative time during which a voltage is applied to
the DC link bus capacitor.
When the main power is shut down, the inverter automatically
measures the discharging time of the DC link bus capacitor and
corrects the elapsed time.
The display method is the same as for
5_06
above.
5_27
Lifetime of DC link bus
capacitor
(remaining hours)
Shows the remaining lifetime of the DC link bus capacitor, which
is estimated by subtracting the elapsed time from the lifetime
(10 years).
The display method is the same as for
5_06
above.
5_28
Cumulative run time of motor 2
Shows the content of the cumulative power-ON time counter of
motor 2.
The display method is the same as for
5_23
above.
