Machine Analyzer (Monitor Area) (FR-A700, A701 with Vector Control)
4
FUNCTION
(7) The frequency characteristics measured by Machine analyzer are displayed in Bode diagram.
For the waveform data, you can change the vertical axis scale and/or move the resonance point and opposite resonance
point cursors.
No. Name Function and Description
A
Setting of the vertical axis scale
Click the [ ] to display the drop-down list. The unit of the vertical axis scale can be
selected from the list.
Click " Y-axis scale optimization" button to automatically change the scale to put the
waveform within the screen.
B
Moving the position of zero in the
vertical axis
Click the [ ]/[ ] button to move the position of zero.
C
Resonance Point, Anti-Resonance
Point cursors
The resonance point (red cursor) and opposite resonance point (yellow cursor) are normally
detected automatically. In case not being detected automatically depending on the
characteristic, move the cursors to the normal positions by directly writing the resonance
point and opposite resonance point frequency.
