Output Voltage Monitoring (D013); Power Monitoring (D014); Cumulative Power Monitoring (D015, B078, B079); Cumulative Operation Run Time Monitoring (D016) - Hitachi L700 SERIES Instruction Manual

4.1.8 Torque monitoring
When the torque monitoring function (d012) is selected, the inverter
displays the estimated value of the torque output from the inverter.
The % monitor lamp lights up while the inverter is displaying the estimated output torque.
(Display)
-300. to +300. in steps of 1 %
Note: This monitoring function is effective only when you have selected the sensorless vector control,
0Hz-range sensorless vector control, or vector control with sensor as the control mode.
Displayed value is not accurate when the other control method is selected.
4.1.9 Output voltage monitoring
When the output voltage monitoring function (d013) is selected, the
inverter displays the voltage output from the inverter.
The V monitor lamp lights up while the inverter is displaying the output voltage.
(Display)
0.0 to 600.0 in steps of 0.1 V
(remark) Displayed value may not be accurate when the output voltage is differ from input voltage.
4.1.10 Power monitoring
When the power monitoring function (d014) is selected, the inverter
displays the electric power (momentary value) input to the inverter.
The kW monitor lamps (V and A lamps) light up while the inverter is displaying the input power.
(Display)
0.0 to 999.9 in steps of 0.1 kW
4.1.11 Cumulative power monitoring
When the cumulative power monitoring function is selected, the inverter
displays the cumulative value of electric power input to the inverter.
You can also convert the value to be displayed to gain data by setting
the cumulative input power display gain setting (b079).
Value displayed by function "d015" = "calculated value of input power (kW/h)"/"cumulative input power
display gain setting (b079)"
The cumulative power input gain can be set within the range 1 to 1000 in steps of 1.
You can clear the cumulative power data by specifying "01" for the cumulative power clearance function
(b078) and pressing the STR key.
You can also clear the cumulative power data at an intelligent input terminal by assigning function "53"
(KHC: cumulative power clearance) to the intelligent input terminal.
When the cumulative input power display gain setting (b079) is set to "1000", the cumulative power data
up to 999000 (kW/h) can be displayed.
(Display)
0.0 to 999.9 in steps of 1 kW/h, or the unit set for function "b079"
1000 to 9999 in units of 10 kW/h, or the unit set for function "b079"
⎡100 to ⎡999 in units of 1000 kW/h, or the unit set for function "b079"
4.1.12 Cumulative operation RUN time monitoring
When the cumulative operation RUN time monitoring function (d016) is
selected, the inverter displays the cumulative time of the inverter
operation.
(Display)
0. to 9999. in units of 1 hour
1000 to 9999 in units of 10 hours
⎡100 to ⎡999 in units of 1,000 hours
