AC Servomotors/Servo Drives 1S-series with Built-in EtherCAT® Communications User’s Manual (I586)
 
• All storable servo parameters are stored in the Servo Drive non-volatile memory.
• Storing is executed only when a specific value is written to subindex 01 hex. This prevents servo 
parameter values from being stored accidentally.
• The specific value means “save”.
• A value of 00000001 hex (command valid) is given when reading.
• If a value other than 65766173 hex is written, an ABORT code is returned.
• Writing to the non-volatile memory may take up to 10 seconds when all objects are changed.
• There is a limit to the number of times to write to the non-volatile memory.
 
 
• Subindex 01 hex Restore Default Parameters can restore the servo parameters and safety settings 
to their default values by the writing of 64616F6C hex (load). The restored servo parameters are 
stored in the non-volatile memory.
• Subindex 03 hex Restore Default Application Parameters can restore the servo parameters to their 
default values by the writing of 64616F6C hex (load). The restored servo parameters are stored in 
the non-volatile memory.
• A value of 00000001 hex (command valid) is given when reading.
• Reset the control power supply to enable the objects.
• If any of the following operation is attempted, an ABORT code is returned.
a) Writing other than the specific value.
b) Writing in the Operation enabled state.
• Writing to the non-volatile memory may take up to 10 seconds. This is when all objects are changed.
• There is a limit to the number of times to write to the non-volatile memory.
