Operation
Parameter Write Mode
Settings changed in the Parameter Setting Mode must be saved in EEPROM. To do so, the 
following procedure must be performed.
1. Saving Changed Settings
2. Returning to the Display of Parameter Write Mode
Key operation Display example Explanation
Press the Mode key to display Parameter Write Mode.
Press the Data key to enter Parameter Write Mode.
Press and hold the Increment key for at least 5 s.
The bar indicator will increase.
Writing will start. (This display will appear only momentarily.)
This display indicates a normal completion. In addition to “Finish,” either 
 or   may be displayed. 
If   is displayed, writing has been completed normally, but some 
of the changed parameters will be enabled only after the power is turned 
ON again. Turn OFF the Servo Drive power supply and then turn it ON 
again.
If   is displayed, there is a writing error. Write the data again.

 If a writing error occurs, write the data again. If a writing error continues to 
occur, there may be a fault in the Servo Drive.
 Do not turn OFF the power supply while writing in EEPROM. Incorrect data 
may be written if the power supply is turned OFF. If the power supply is 
turned OFF, perform the settings again for all parameters, and write the 
data again.
 Do not disconnect the Parameter Unit from the Servo Drive during the time 
from writing start (“Start”) to writing completion (“Finish” or “Reset”). If the 
Parameter Unit is disconnected, repeat the procedure from the beginning.
