Setting parameters from flash memory [Sequence program]

This subsection explains how to set positioning parameters and servo parameters from the flash memory at
startup.
Because the parameter setting program is not required for the operation program, create it as a subroutine
sequence as in the program example, create and execute it separately from the operation program.
→ For direct specification of the buffer memory using the FROM/TO instruction and applied
Caution for using a 20SSC-H earlier than Ver. 1.10
Use FX Configurator-FP when changing servo parameters.
When changing servo parameters using a sequence program, change servo parameters stored in the buffer
memory in the following status, save servo parameters to the flash memory, and then turn OFF and ON again
the power of the servo amplifier and PLC (including the 20SSC-H).
• Status in which the power of the servo amplifier is OFF
• Status in which the servo amplifier is not connected to the 20SSC-H
Before turning ON the power of the PLC (including the 20SSC-H) again, connect the servo amplifier to the
20SSC-H.
• Status in which each flag of servo status 2 is as follows
Do not change servo parameters in the servo amplifier when changing servo parameters in the 20SSC-H.
If servo parameters are changed in the servo amplifier, update of servo parameters is automatically
started.
Servo status 2
Note
When using this setting method, make sure to set the following positioning parameters and servo parameters
stored in the flash memory as follows.
• Positioning parameters (Ver. 1.10 or later)
Set the servo parameter transfer mode as follows.
Operation
parameter 2
• Servo parameters
Set the servo series as follows.
Servo series
*1. When connecting the MR-J3W- B, set "MR-J3-B" as the servo series.
*2. The MR-J3- BS can be set for 20SSC-H blocks later than Ver.1.40.
