In systems connected to MECHATROLINK, SERVOPACK parameters can be read directly from the MP2300. (Refer
to
11.6 Parameters That Are Automatically Updated
in the
Machine Controller MP2000 Series Built-in SVB/SVB-01
Motion Module User’s Manual
(Manual No.: SIEPC88070033). 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.
B.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.
Indicates data has been written (same below).
( 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 parameters*. RAM in the
SERVOPACK are written.
* Refer to
4 Motion Prameters
of the
Machine Controller MP2000 Series Built-in SVB/SVB-01 Motion Mudule User’s
Manual
(Manual No.: SIEPC88070033).
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.
