4.3.4 Operation monitoring screen panel
If master controller of N5000 inverter is powered on, first screen of operator on the front inverter
panel displays a picture of figure 9, operation monitoring screen panel, after 3 sec. Overall
conditions of the inverter can be monitored thorough this screen. User cannot change the values.
Only, it displays the conditions of the inverter. The contents are shown below.
Figure 9. Operation monitoring screen panel
(1)
Commanding frequency: user defined input/revised frequency. It only displays frequency in
[Hz] unit. Commanding frequency in this screen is set in the operation controlling screen panel.
(2)
Output frequency: displays present output frequency. It displays [Hz] unit.
(3)
Operating condition: displays the rotational direction of a motor. You can change the rotational
direction in operating controlling screen panel.
(4)
Output current: displays output current of inverter in [A] unit. (An average value of 3-phase
currents).
(5)
Output voltage: displays output voltage of inverter in [V] unit. (An average value of 3-phase
voltages).
(6)
Motor speed: displays the number of rotations of motor in [RPM] unit. When a speed
measurement sensor is attached, measured motor speed is displayed. When it is not attached,
the calculated motor speed is displayed.
(7)
Boost frequency: displays boost frequency in [Hz] unit.
(8)
Boost voltage: displays boost voltage in [V] unit.
[notice] when boost mode is ON in screen 3 of the group A, the set values of boost frequency and boost
voltage (entered in screen 3 of group A) are displayed, When boost mode is OFF, 0 is displayed for
boost frequency and boost voltage.
(9)
Output power: displays output power in [kW] unit.
(10)
Accumulated operating time: displays the accumulated actual operating (generating inverter
gate signal) time of inverter.
