Item Description
5_11
Number of RS-485
communications errors
(COM port 1)
Shows the total number of errors that have occurred in RS-485
communication (COM port 1, connection to keypad) after the power is
turned ON.
Once the count exceeds 9999, the counter will be reset to "0."
5_12
Content of RS-485
communications error
(COM port 1)
Shows the latest error that has occurred in RS-485 communication (COM
port 1) in decimal.
For error contents, refer to the RS-485 Communication User’s Manual.
5_13
Number of option errors 1
Shows the total number of errors that have occurred in the option being
connected to the A-port. Once the count exceeds 9999, the counter will be
reset to "0."
5_14
Inverter's ROM version Shows the inverter's ROM version as a 4-digit code.
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 to be connected to A-port as a
4-digit code.
If the option has no ROM, "
----
" appears on the LED monitor.
5_20

----
" 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
5_25
Temperature of heat sink
(real-time value)
Shows the current temperature of the heat sink inside the inverter.
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.
5_29
Cumulative run time of motor 3
Shows the content of the cumulative power-ON time counter of motor 3.
The display method is the same as for
