5.6 Incremental value command method

When using this servo amplifier in incremental value command method, change the setting of [Pr. PT01].

As position data, set the travel distance from the current address to the target address. The incremental value command method enables infinitely long constant rate of feeding.

Setting range: -999999 to 999999 [×10 STM μ m] (STM = Feed length multiplication [Pr. PT03])

-999999 to 999999 [×10 (STM-4) inch] (STM = Feed length multiplication [Pr. PT03])

-999999 to 999999 [pulse]

Current address Target address

Position data = |Target address - Current address|

This section indicates contents different from the absolute value command method (factory setting) when this servo amplifier is used under the incremental value command method.

(1) Parameter setting

Set [Pr. PT01] to select the incremental value command method as shown below.

(2) Command

The command contents of "MOV" and "MOVA" are changed as follows. There is no change in other commands. Thus, the command contents are the same between "MOV" and "MOVI", and between

"MOVA" and "MOVIA".

The servo motor rotates using the set value as the incremental value.

The same as "MOVI" command

The servo motor rotates continuously as the set incremental value.

Make sure to describe this command after the

"MOV" command. If this command is described after other command, an error will occur.
