Chapter 7 Motion Control

7.2.2 Description of Data Array

Many functions of motion control, such as CAPTURE, COMPARE, and E-Cam (A2-L does not
support E-Cam function), are the data that needs to be saved in large amount of memory space.
Therefore, the servo drive reserves a continuous internal space to satisfy the need. The main
feature of the data array is as the followings:
Usage
Size of Data Array
Data Retained
Accessing Window
The content of the data array cannot be read or written directly. You need to read or write the
data via parameters P5-10 ~ P5-13. The description of the parameters is as the followings:

Feature Introduction of Data Array
Save the captured data of CAPTURE

Save the compared value of COMPARE

Save the contour table of E-Cam

Note:
1. The system does not partition off the data array into the individual space
of CAP, CMP, and E-Cam. The user could program it according to the
demand. Therefore, the space might be overlapped. Please pay close
attention to it when using.
2. A2-L does not support E-Cam function.
32-bit integer x 800 (refer to P5-10)

Each data has its corresponding address. Specify the address is

a must when reading or writing the data.
The 800 data is from 0 to 799.

Manually set up the saving (P2-08 = 30, 35) is a must and the

data should be saved in EEPROM of the servo drive.
Save the data when it is Servo Off.

The data will be loaded into data array automatically when it is

Servo On.
Should be accessed via parameters P5-10 ~ P5-13.
