11.3 SERVOPACK Parameter Data Flow
In systems connected to MECHATROLINK, SERVOPACK parameters can be read directly from the
MP2300. (Refer to 11.1 Parameters That Are Automatically Updated on page 11-2.) This means that
parameters are saved in the memory area of both the MP2300 and the SERVOPACK. It is thus
necessary to consider the relationship between the settings in both memory areas.
11.3.1 Operations and Parameter Data Flow
( 1 ) Power ON
• Parameter data saved in the SERVOPACK’s EEPROM
*1
is copied to SERVOPACK’s RAM.
• Parameter data saved in the MP2300’s flash memory
*1
for all axes is copied to SDRAM
*2
.
Some gain-related settings are sent from the MP2300 to SERVOPACK RAM
*1
.
* 1. EEPROM, flash memory, and SRAM: Store data even when the power is turned
OFF.
* 2. RAM (SRAM, SDRAM): Lose data when the power is turned OFF.
