7.1 Note on Setting Parameters
7.1.5
Setting parameters from the buffer memory [sequence program] (Ver. 1.10 or later)
This subsection explains how to set positioning parameters and servo parameters from the buffer memory.
→
For direct specification of the buffer memory using the FROM/TO instruction and applied
instructions. Refer to Section 12.1 and the PROGRAMMING MANUAL
Note
When using this setting method, make sure to set the following servo series of servo parameters stored in the
flash memory as follows.
In the setting program example mentioned later, when the servo series is set except for "K0", system reset is
executed, after initializing the positioning parameters and servo parameters in the buffer memory and flash
memory.
Moreover, parameters are set up after initializing them in the buffer memory.
Set the servo series as follows.
1) Setting the positioning parameters stored in the buffer memory
Save the set value of servo positioning parameters by direct specification of the buffer memory using the
FROM/TO instruction and applied instructions to the buffer memory.
→
For the contents of setting of positioning parameters, refer to Section 11.1
Set the servo parameter transfer mode as follows.
2) Setting the following servo parameters except the servo series
Save the set value of servo parameters by direct specification of the buffer memory using the FROM/TO
instruction and applied instructions to the buffer memory.
→
For the contents of setting of servo parameters, refer to Section 11.2
3) Setting to ON from OFF the positioning parameter enable command
When the positioning parameter enable command is set to ON from OFF while the target axis is not
performing positioning operation, the system will use the changed positioning parameters from next
positioning operation.

For the operation command 2, refer to Subsection 11.4.11
