• When setting a servo parameter using a combination of several digits
[Pr. PA01] =

A
For example, if the servo parameter name is "Function selection A-1", the setting digit name is "Forced stop deceleration
function selection", and the setting digit is the forth last digit in PA04, the servo parameter is expressed as shown below.

Object dictionary
MR-JET servo amplifiers communicate information such as position commands and position feedback via a network. For
identification, each information is assigned to a unique number from 0000h to FFFFh called Index, and the assigned
information is called an object.
For example, the command position is the object that is assigned to the Index of 607Ah. A servo amplifier has a huge number
of objects, which are called an object dictionary in the aggregate.
The basic functions described in this manual also describe the method of use of the objects, as there are operations that give
commands to the servo amplifier through objects, as well as operations that notify status to the controller through objects.
When using a controller manufactured by Mitsubishi Electric, any concern regarding the Objects is alleviated as the controller
itself has the functions to set and obtain the Object values necessary to implement each function. When the respective object
values are needed to be obtained and set specifically, use the servo cyclic transmission function or the servo transient
transmission function. For details, refer to each controller manual.
The objects related to the basic functions explained in this manual are shown in the following example.
Ex.
[Target position (Obj. 607Ah)]
Index
Sub
Object
607Ah
VAR
For details on how to save the content set in the object, refer to "Saving object dictionary data" in the User's Manual
(Communication Function).
