7.2.2 Data Array
ASDA-A2 series provides many motion control functions, such as E-Cam (ASDA-A2 series L
type models does not provide this function.), Capture function, and Compare function.
The data array can keep data for E-Cam, Capture function, and Compare function with
maximum to 800 records (all together to max. 800 records). Please refer to the following
table for the introduction of data array.
Usage
Array Size
Backup Data Into
EEPROM
Read/Write Window
The content of the data array can not be read and written via external commands. It only
can be read and written through the settings of P5-10 ~ P5-13. Please refer to the
following table for explanation:


Save Capture data.

Save Compare data.

Save E-Cam curve.
Note:
1. The data array is user-defined and the system will not partition
off the data array for Capture, Compare and E-Cam function
respectively. Therefore, the memory blocks of the data array
may be overlapped. Please pay close attention when defining
the data array.
2. ASDA-A2 series L type models does not provide this function.

32-bit integer x 800 records (the data address when reading
and writing data array is determined by P5-10).

Each data should have a corresponding address. This address
should be specified when reading and writing data array.

The address is within the range of 0 ~ 799.

Set P2-08 to 30 first and set to 35 next. Then, the content of
the data array will be saved in EEPROM when power is off.

Please save data when Servo Off.

After re-power the servo drive, the content of the data array
will be written automatically.

Perform read and write operation through P5-10 ~ P5-13.
