13.4.1 Display flowchart
Use the display (3-dight, 7-segment LED) on the front panel of the converter unit for status display, parameter
setting, etc. Set the parameters before operation, diagnose an alarm, confirm external sequences, and/or
confirm the operation status.
Press the MODE, UP or DOWN button once to move the next screen.

13.4.2 Status display mode
The servo status during operation is shown on the 3-digit, 7-segment LED display. Press the "UP" or "DOWN"
button to change display data as desired.
When the required data is selected, the corresponding symbol is displayed. Press the "SET" button to display
that data.
The converter unit display section can show four items of data such as the effective load factor.
(1) Display examples
The following table shows the display examples.
