4. OPERATION
4.7 Incremental value command system
To use this servo amplifier in the incremental value command system, the setting of parameter No. 0
must be changed.
As the position data, set the moving distance of (target address - current address). Fixed-pitch feed of
infinite length is enabled in the incremental value command system.
Setting range:
999999 to 999999 [ 10
STM
m] (STM = feed length multiplication parameter No. 1)
Current address Target address
Position data = | target address - current address |
This section describes the points that differ from the absolute value command system (factory setting) in
using this servo amplifier in the incremental value command system.
(1) Parameter setting
Set parameter No. 0 as shown below to select the incremental value command system.

(2) Commands
The "MOV" and "MOVA" commands change as described below. The other commands remain
unchanged. Hence, "MOV" and "MOVI" have the same function, and "MOVA" and "MOVIA" have the
same function.

Description
MOV
Incremental
move command
MOV (Set value)
999999
to 999999
10
STM
m
The set value is regarded as an
incremental value for movement.
This command has the same
function as the "MOVI" command.
MOVA
Incremental
continuous move
command
MOVA (Set value)
999999
to 999999
10
STM
m
The set value is regarded as an
incremental value for continuous
movement.
Always describe this command
after the "MOV" command.
Describing it after any other
command will result in an error.
This command has the same
function as the "MOVIA"
command.
