1.4.5 Data State
Click the ‘Data State’ button in the Real-Time Data Screen to view the MVC data state, as

for an industrial lift (load) MVC vector control is shown in Fig.1-32.

1.4.6 Synchronoscope
If the MVC is used on a site where the grid connection function is required, and the
‘Grid-Connection’ permission is set to ‘Yes’ in the ‘System – Function’ settings, then the Real
Time Data Screen will display the ‘Synchronoscope’ button. Click the ‘Synchronoscope’ button to
view the Synchronoscope State. As shown in Fig.1-33: the function of the synchronoscope in the
figure is when the control system detects the MVC output voltage and grid voltage to be the same
in the aspects of frequency, phase and amplitude. The middle synchronizing indicator above the
synchronoscope will flash once instantly when within the allowable error range.
