( 2 ) Normal Operation
1.
Control software of the SERVOPACK operates based on the parameter data held in SERVOPACK’s
RAM.
2.
Some of MP2300S setting parameters and commands temporarily change SERVOPACK parameters.
Refer to Chapter 4 in Machine Controller MP2000-series SVB/SVB-01 Motion Module User’s Manual
(manual number: SIEP C880700 33) for details. RAM in the SERVOPACK are written.
Œ Parameters held in the SERVOPACK’s RAM are displayed on a Digital Operator connected to the SERVO-
PACK. 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 Defini-
tions Window on the MPE720 (refer to 2.2.5 ( 5 ) SVB Definition
for details on how to open the SERVOPACK Tab
Page.)
1.
The MPE720 writes and displays the parameters that are held in the SERVOPACK’s RAM for the rele-
vant axis to the Current Value in the SERVOPACK Tab Page.
It also reads and displays the values that are held in the MP2300S’s SDRAM values to the Input Data
in the SERVOPACK Tab Page.
