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.

	General-purpose register		Setting
	R1		1000
	R2		2000
	D1		200
	D2		300
	Program			Description
SPN (1000)		Speed (Motor speed)		1000 [r/min]			a)
STA (D1)		Acceleration time constant		D1=200 [ms]			b)
STB (D2)		Deceleration time constant		D2=300 [ms]			c)
MOVI (R1)		Incremental move command		R1=1000 [	10STM	m]	d)
TIM (10)		Dwell command time		100 [ms]			e)
MOVI (R2)		Incremental move command		R2=2000 [	10STM	m]	f)
