6. DISPLAY AND OPERATION
6.1 Display flowchart
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
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).

(Note)
Note. The initial status display at power-on depends on the control mode.
Position control mode: Cumulative feedback pulses(C), Speed control mode: Motor speed(r),
Torque control mode: Torque command voltage(U)
Also, parameter No. 18 can be used to change the initial indication of the status display at power-on.
