7.2.2 Description of Data Array

Many functions of motion control, such as CAPTURE, COMPARE and E-Cam 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 data array cannot be read or wrote directly, reading or writing the data
must via parameter 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: 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.

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 access via parameter P5-10 ~ P5-13.
