SERVOPACK Parameter Data Flow

When performing motion control, you can read and write SERVOPACK parameters from the
MP3000.
3.5 Automatically Updated Parameters on page 3-86
This means that the parameter settings are saved in both the MP3000 and in the slave SERVO-
PACK. Therefore, it is necessary to consider the relationship between the settings in both
places.
This section describes the flow of data for the SERVOPACK parameters under different condi-
tions.
The following descriptions of procedures and conceptual diagrams are for the SVC Function
Module.

When the Power Supply Is Turned ON

The flow of data for the SERVOPACK parameters when the power supply is turned ON is
shown below.
1.
The parameter data in the SERVOPACK's EEPROM
2.
The MP3000 copies the parameter data for all axes from flash memory
3.
Some gain settings are written from the MP3000 to the SERVOPACK RAM
