
Cumulative operation time alarm monitor (FE79)
Comulative operation time alarm monitor (current status): "Communication Number FE79"
Bit
0 Fan life alarm
1 Circuit board life alarm
2 Main-circuit capacitor life alarm
3 User set alarm
4-15 (Undefined)
Note: The bit described "Undefined" is unstable. Don't use the bit for the judgment.

Output motor speed monitor (FD90, FE90)
Output motor speed monitor (current status): "Communication Number FD90" (unit: 1min
Output motor speed monitor (status immediately before the occurrence of a trip): "Communication
Number FE90" (unit: 1min
Ex.: Output motor speed monitor (during 60 Hz operation and 4 poles ( f856 = 2 : 4 poles )
... (0708H = 1800d, 1800min
The number of motor poles is selected by f856 .
The output moter speed is converted from the output frequency by the following calculation formula.
Output morter speed [min
1800 min
