Table 5.16 "Maintenance Information" Display Items
Code
Shows cumulative time inverter's main power has been on.
Time Reverts to 0 after exceeding 65,535 hours and begins counting up
again.
Edc Shows DC link bus voltage of inverter's main circuit.
Shows as the effective value the maximum inverter output
Imax
current each hour.
Shows cumulative power level. Reverts to 0 after passing
Wh
1,000,000 kWh.
Cumulative power data shown as cumulative power level (kWh)
PDat x function code K32. (Display range: 0.001–9999; data of 9999
or higher is limited to 9999.)
Current capacity of main circuit capacitor is shown, using
capacity at time of shipment as 100%. For details, refer to
Cap
"Chapter 10. Maintenance and Inspection" in the inverter unit
instruction manual.
Shows as total elapsed time the period during which a voltage has
been applied to the electrolytic capacitor on the main circuit. The
EneT capacity of the electrolytic capacitor on the main circuit is
measured when the main power is OFF, and elapsed time is
revised.
Shows the remaining life of the electrolytic capacitor on the main
RemT circuit. Remaining life is calculated by subtracting elapsed time
from the service life (five years).
Shows as cumulative run time the product of the cumulative
amount of time during which a voltage has been applied to the
EneT
electrolytic capacitor on the PCB times a coefficient to account
for ambient temperature conditions.
Shows the remaining life of the electrolytic capacitor on the PCB.
Life Remaining life is calculated by subtracting elapsed time from the
service life (five years).
Shows the total amount of time the cooling fan has been in
operation. Time when the cooling fan ON-OFF control (function
EneT
code H06) is enabled and the cooling fan is off is not counted.
Shows the cooling fan's remaining service life. Remaining life is
Life calculated by subtracting elapsed time from the service life (five
years).
Shows the motor's cumulative run time. Reverts to 0 after
EneT
exceeding 99,990 hours and begins counting up again.
Shows the amount of time remaining until the next maintenance.
The value shown is calculated by subtracting cumulative motor
RemT
run time from the set maintenance time (H78).
Accumulates and shows the number of motor operations (the
number of times the inverter run command has been ON).
EneN
Reverts to 0 after exceeding 65,535 times and begins counting up
again.
Indicates the number of startups until the next maintenance. The
RemN value shown is calculated by subtracting the number of startups
from the maintenance setting for the number of startups (H79).
