Display Contents
Cumulative run
time
DC link bus voltage
Displays the content of the accumulative power-on time counter
of the inverter.
Measurement Range: 0~65,535 h
Display: Divided the accumulative run time into interactive
display of front 2 bits and back 3 bits.
E.g. 0
�
535h (535 h)
65
�
535h (65,535 h)
When the back 3 bits are displayed, it displays h (hour) at the
final bit.
When the count exceeds 65,535 hours,the counter will be reset
to "0" and start over again.
Displays the content of the cumulative time counter of voltage
application to the electrolytic capacitor on the PCB, Which is
calculated by multiplying by the cumulative time count by the
coefficient based on the surrounding temperature condition.
Measurement Range: 0~99,990 h
Display: 0~9999 ×10 LED on
(cumulative running time of electrolytic capacitor on the
PCB= Display × 10 h)
If it is beyond 99,990 h, it stops cumulation action. The display is
maintained at 9999.
Displays the DC link bus voltage of main circuit of inverter. Unit: V
Displays the maximum current in RMS for per hour. Unit: A
Cumulative starting times of the 1st motor and display value
Measurement Range: 0~65,530 times
Display: 0~9999
If it is beyond 10,000 times, ×10 LED is on. It displays by dividing
the times by 10.
When it is beyond 65,530 times, it will be reset to”0” and start over
again
Displays Input watt hour
Displays: 0.001~9999
Input watt hour= “Display” × 100kWh
It can reset Input watt hour and accumulative power data
through setting functional parameter 01
．
51 as “0.000”
When it is beyond 999,900kWh, it will be reset to”0” and start
over again.
Displays the max temperature –inside of the inverter for per hour.
Unit:
℃
(it displays 20
℃
when it is below 20
℃
.)
Displays the max temperature of –cooler for per hour. Unit:
℃
(it displays 20
℃
when it is below 20
℃
.)
Displays the content of the cumulative running time of the cooling fan.
When the cooling fan ON-OFF control (functioncode 04.06) is valid
and the fan stops, the counter does not work.
Displays method is the same with E_06.
