Updating positioning parameters [sequence program]
This subsection explains the method to enable positioning parameters changed in a sequence program.
→
For direct specification of the buffer memory using the FROM/TO instruction and applied
instructions, refer to Section 12.1 and the PROGRAMMING MANUAL
1) Set the following positioning parameters stored in the buffer memory using a sequence program.
Create a program which sets positioning parameters by direct specification of the buffer memory using
the FROM/TO instruction and applied instructions, and then save set values to the buffer memory.
→
For the contents of setting of positioning parameters, refer to Section 11.1
2) Set to ON from OFF the positioning parameter enable command.
If the positioning parameter enable command is set to ON from OFF while the target axis is not
performing a positioning operation, the system will use the positioning parameters stored in the buffer
memory from the next positioning operation.
If this command is not executed, the system performs positioning operation using the positioning
parameters stored in the flash memory.

For the operation command 2, refer to Subsection 11.4.11
Program example
In this program example, the following positioning parameters in unit No. 1 are changed, and then the
changed positioning parameters are enabled.
