7.1 Note on Setting Parameters
7.1.8 Updating some servo parameters [sequence program]
This subsection explains how to transfer the following servo parameters changed using a sequence program
to the servo amplifier.
The table below shows transferrable servo parameters in accordance with the setting of the auto tuning
mode.
→ For operation command 2, refer to Subsection 11.4.11
→ 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. These parameters are automatically adjusted in the interpolation mode.
*2. These parameters are automatically adjusted in auto tuning mode 1.
*3. These parameters are automatically adjusted in auto tuning mode 2.
Note: Servo parameter transfer command execution condition
The servo parameter transfer command is enabled when the "READY/BUSY" bit in the status information is
"READY (ON)."
The servo parameter transfer command is ignored while the system is performing positioning operation.
1) Set the following servo parameters to be transferred stored in the buffer memory.
Create a program which sets servo 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 servo parameters, refer to Section 11.2
