4. OPERATION

(j) Indirect addressing using general-purpose registers (R1-R4, D1-D4)

The set values of the "SPN", "STA", "STB", "STC", "STD", "MOV", "MOVI", "MOVA", "MOVIA",
"TIM" and "TIMES" commands can be addressed indirectly.
The values stored in the general-purpose registers (R1-R4, D1-D4) are used as the set values of the
commands.
Change the values of the general-purpose registers using the communication command when the
program is not being executed by the communication command. (Refer to Section 15.12.13)
The data of the general-purpose registers are erased at power-off of the servo amplifier. Note that
the data of the general-purpose registers (R1-R4, D1-D4) can be saved in the EEP-ROM.
The setting ranges of the general-purpose registers are the setting ranges of the instructions with
which the general-purpose registers are used.

The following explains the case where the general-purpose registers are set as indicated below
before execution of the program.
