(2) When function code E45 (LCD monitor item selection) is set at "1"<br />
The LCD monitor displays the output frequency, output current, and calculated torque in a bar chart.<br />
(The upper indicators show the unit of values displayed on the LED monitor as detailed in Section 3.3.2. The lower<br />
ones show the running status and run command source.)<br />

Output frequency<br />
Output current<br />
Calculated torque<br />
The full scale (maximum value) for each parameter is as follows:<br />
Output frequency: Maximum frequency<br />
Output current: 200% of inverter’s rated current<br />
Calculated torque: 200% of rated torque generated by motor<br />

3.3.2 Monitoring the running status on the LED monitor<br />
The items listed below can be monitored on the 7-segment LED monitor. Immediately after the power is turned ON, the<br />
monitor item specified by function code E43 is displayed.<br />
Pressing the key in Running mode switches between monitor items in the sequence shown in Table 3.4. The "Monitor<br />
page #" column shows the monitor page of the items supported.<br />
