Saving object dictionary data

Some of object dictionary data is stored in a non-volatile memory and some is not. Use [Store Parameters (Obj. 1010h)] for
storing the object dictionary data in the non-volatile memory.
For details about objects that can be stored in the non-volatile memory, refer to the following manual.
MR-JET-G-N1 User's Manual (Object Dictionary)

Store parameters

Writing "65766173h" (= reverse order of the ASCII code "save") to [Store parameters (Obj. 1010h: 01h)] enables the setting
value of an object to be stored in the non-volatile memory of the servo amplifier.
It can take up to around 25 s for [Save all parameters (Obj. 1010h: 01h)] to write all the parameters. Do not shut off the power
supply during writing.
Index Sub
1010h 0
1
Reading [Save all parameters (Obj. 1010h: 01h)] will produce the following values. Bit 0 is "0" during saving and "1" when not
saving.
Bit
0
1
Precautions
To shut-off the power supply after executing Store parameters, make sure that a save is not in progress (bit 0 is on) before
shutting off the power.

Restore default parameters

Objects can be reset to the factory setting.
Writing "64616F6Ch" (= reverse order of the ASCII code "load") to [Restore all default parameters (Obj. 1011h: 01h)] followed
by cycling the power starts object initialization. Writing a value other than "load" (= 64616F6Ch) triggers an error. Initialization
can take up to around 25 s.
Index Sub
1011h 0
1
Reading [Restore all default parameters (Obj. 1011h: 01h)] will display "00000001h" (command valid).
