Precautions for Using the MP2300
11.3.1
Operations and Parameter Data Flow
11-10
( 2 ) Normal Operation
• Control software of the SERVOPACK operates based on the parameter data held in
SERVOPACK’s RAM.
• Some of MP2300 setting parameters and commands temporarily change SERVOPACK parame-
ters (refer to Chapter 6 Motion Parameters for details). RAM in the SERVOPACK are written.

Parameters held in the SERVOPACK’s RAM are displayed on a Digital Operator connected
to the SERVOPACK. They are also written to EEPROM when the DATA/ENTER Key is
pressed.
( 3 ) When the SERVOPACK Tab Page Is Open
The data flow for SERVOPACK parameters is as follows when the SERVOPACK Tab Page is open
in the SVB Definitions Window on the MPE720 (refer to 2.1.6 ( 4 ) Set and Save Motion Fixed
Parameters on page 2-28 for details on how to open the SERVOPACK Tab Page.):
• The MPE720 writes and displays the parameters that are held in the SERVOPACK’s RAM for the
relevant axis to the Current Value in the SERVOPACK Tab Page.
It also reads and displays the values that are held in the MP2300’s SDRAM values to the Input
Data in the SERVOPACK Tab.
The following figure shows an example of the SERVOPACK Tab in the SVB Definition Window.
