Appendix B  SERVOPACK Parameter Data Flow
B.1  Operations and Parameter Data Flow
A-26
( 6 ) Changing Parameters in the SERVOPACK Tab Page
The data flow for SERVOPACK parameters is as follows when parameters for the cursor position are changed from the 
SERVOPACK Tab Page in the SVB Definition Window for MPE720: 
1. The MPE720 writes parameters of the relevant axis to the followings when the Enter Key is pressed on 
the computer. (The parameters other than those of the relevant axis will not be written.)
• Input Data (set data) on the SERVOPACK Tab Page
• SDRAM of the MP2300S
• RAM of the SERVOPACK
2. After having completed writing, the MPE720 updates the values in Input Data on the SERVOPACK 
Tab Page with the parameter values stored in the RAM of the SERVOPACK.
