3.4.4 Current Value and Setting Data in SVB
In systems connected to MECHATROLINK, SERVOPACK parameters can be read or written directly from the
Machine Controller. (Refer to 11.6 Parameters That Are Automatically Updated.) This means that parameters are saved
in the memory areas of both the Machine Controller and the SERVOPACK. It is thus necessary to consider the relation-
ship between the settings in both memory areas.
The flow of data for the SERVOPACK parameters under different conditions is described here.
( 1 ) Power ON
• Parameter data saved in the SERVOPACK’s EEPROM *1 is copied to SERVOPACK’s RAM.
• Parameter data saved in the Machine Controller’s flash memory
*1
for all axes is copied to SDRAM
*2
.
Some gain-related settings are sent from the Machine Controller to SERVOPACK RAM *1 .
* 1. EEPROM, flash memory, and SRAM: Can store data even when the power is turned OFF.
* 2. RAM and SDRAM: Can lose data when the power is turned OFF.
indicates data has been written.
( 2 ) Normal Operation
• Control software of the SERVOPACK operates in accordance with on the parameter data held in the SERVO-
PACK’s RAM.
• Some setting parameters and commands of the Machine Controller temporarily change SERVOPACK parame-
ters. The RAM in the SERVOPACK is also changed. (Refer to Chapter 4 Motion Parameters for details.)
Parameters held in the SERVOPACK’s RAM are displayed on a Digital Operator connected to the SERVO-
PACK. Press the DATE/ENTER Key to write the parameters to the EEPROM.
