2-3-1 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
move to the next screen. In the position control mode, switching power on displays the symbol C
of the cumulative feedback pulses.
To refer to and/or set the expansion parameters, make them valid with parameter No. 19 (parameter
write disable).
