Use the display (5-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

The automatic scroll mode is selected at power-on. Before starting use, therefore, press the "UP" or
"DOWN" button to change the fifth digit to the necessary slot number "1" to "8" and press the "MODE"
button for 2s or more to change the indication.
Press the "MODE" "UP" or "DOWN" button once to move to the next screen.
