Chapter 7 Motion Control ASDA-A2R SeriesRevision December, 2014 7-97.2.2 Description of Data ArrayMany functions of motion control, such as CAPTURE, COMPARE and E-Cam are thedata that needs to be saved in large amount of memory space, therefore, the servodrive reserves a continuous internal space to satisfy the need. The main feature of thedata array is as the followings:Feature Introduction of Data ArrayUsage Save the captured data of CAPTURE Save the compared value of COMPARE Save the contour table of E-CamNote: The system does not partition off the data array into theindividual space of CAP, CMP and E-Cam. The user couldprogram it according to the demand. Therefore, the spacemight be overlapped. Please pay close attention to it whenusing.Size of Data Array 32-bit integer x 800 (refer to P5-10) Each data has its corresponding address. Specify theaddress is a must when reading or writing the data. The 800 data is from 0 to 799.Data Retained Manually set up the saving (P2-08 = 30, 35) is a must andthe 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 itis Servo On.Accessing Window Should be access via parameter P5-10 ~ P5-13.The content of data array cannot be read or wrote directly, reading or writing the datamust via parameter P5-10 ~ P5-13. The description of the parameters is as thefollowings:Description of Related Parameter about Data ArrayParameter Name DescriptionP5-10 Size of dataarray Return the size of data array (read-only)P5-11Reading /writingaddressSet the desired address of reading and writingP5-12 Reading /writingwindow #1Read via panel: After reading the content of P5-11, thevalue of P5-11 will not change.Write via panel: After writing the content of P5-11, the valueof P5-11 will increase 1 automatically.------------------------------------------------------------------------------Read via communication: After reading the content ofP5-11, the value of P5-11 willincrease 1 automatically.Write via communication: After writing the content of P5-11,the value of P5-11 will increase 1automatically.P5-13 Reading /writingwindow #2Read via panel: After reading the content of P5-11, thevalue of P5-11 will increase 1automatically.
