The cumulative energization time and actual operation time are accumulated from 0 to 65535 hours, then cleared, and accumulated again from 0.
The actual operation time does not increase if the cumulative running time before power OFF is less than an hour.
On the parameter unit (FR-PU07), "kW" is displayed
The output current is regarded as 0 A when the current is less than the specified level (5% of the rated inverter current). Therefore, each readout
of an output current and output power may show "0" if a too small-capacity motor is used as contrasted with the inverter capacity and the output
current falls below the specified value.
The details of bits for the input terminal status are as follows. (1: ON state, 0: OFF state of a terminal on the inverter. "—" denotes an indefinite
The details of bits for the output terminal status are as follows. (1: ON state, 0: OFF state of a terminal on the inverter. "—" denotes an indefinite
The monitored values are retained even if an inverter fault occurs. Resetting clears the retained values.
Parameter setting is not available for setting the item as the main monitor item on the LCD operation panel (FR-LU08) or the parameter unit (FR-
PU07). Use the monitor function of the FR-LU08 or the FR-PU07 for setting.

Monitoring I/O terminals on the operation panel (Pr.774 to Pr.776)
= "55", the I/O terminal state can be monitored on the operation panel.
Pr.774 to Pr.776
The power at the inverter output side is displayed.
The cumulative energization time since the inverter
shipment is displayed.
The cumulative operation time is displayed.
The output current value is displayed as a percentage,
considering the inverter rated current value as 100%.
Readout (%) = present output current value / inverter
rated current value × 100
The cumulative energy based on the monitored output
power is displayed. Use Pr.170 to reset it.
The set point, measured value, or deviation during PID
control operation is displayed. (Refer to
The ON/OFF state of the input terminals on the inverter
The ON/OFF state of the output terminals on the
inverter is displayed.
The accumulated heat value of the motor thermal O/L
relay is displayed.
The motor overload trip (electronic thermal O/L relay
function) (E.THM) occurs at 100%.
The accumulated heat value of the inverter thermal O/L
relay is displayed.
The inverter overload trip (electronic thermal O/L relay
function) (E.THT) occurs at 100%.
