6.1 Display Flowchart
Use the display (4-digit, 7-segment LED) on the front panel of the servo amplifier 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
to the next screen.
To refer to or set the expansion parameters, make them valid with parameter No. 19 (parameter write
disable).
