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

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.

MOV

Incremental
move command

MOV (Set value)

999999

to 999999

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

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.
