8.2.Monitoring from the computer
This section explains how to monitor the operating status of the inverter from the computer.
Monitoring of the output frequency from the computer (FD00, FE00)
Output frequency (current status): “Communication Number FD00” (unit: 0.01Hz)
Output frequency (status immediately before the occurrence of a trip): “Communication Number
FE00” (unit: 0.01Hz)”
The current output frequency is read out in hexadecimal in units of 0.01Hz. For example, if the out-
put frequency is 80Hz, 1F40H (hexadecimal number) is read out. Since the unit is 0.01Hz, 1F40H
(hexadecimal number) = 8000 (decimal number) x 0.01 = 80 (Hz)
Example: Monitoring of the output frequency (operation frequency: 50Hz) ・・・ (1F40H=8000d,
8000×0.1=80Hz)

Monitoring of the output current with the computer (FD03, FE03)
Output current (current status): “Communication Number FD03” (unit: 0.01%)
Output current (status immediately before the occurrence of a trip): “Communication Number FE03”
(unit: 0.01%)
The current output current is read out in hexadecimal in units of 0.01%. For example, if the output
current of an inverter with a current rating of 4.8A is 2.4A (50%), 1388H (hexadecimal number) is
read out. Since the unit is 0.01%, 1388H (hexadecimal number) = 5000 (decimal number) x 0.01 =
50 (%)
Example: Monitoring of the output current (output current: 90%) ・・・ (2328H=9000d,
9000×0.01=90%)

The following items are also calculated in the same way.
• FD05 (output voltage)..........................................Unit: 0.01% (V)
• FD04 (DC voltage) ..............................................Unit: 0.01% (V)
