12.8 Control Data
[Cd.132] Change data
• Set the change value of servo parameter set in "[Cd.131] Parameter No. (Setting for servo parameters to be changed)".
Fetch cycle: At change request
■ Setting value
• Set with a decimal or hexadecimal.
[1 word write request]
When "1" is set in "[Cd.130] Servo parameter write request", set the change value to low-order buffer memory. The value set
to high-order buffer memory is invalid.
[2 words write request]
When "2" is set in "[Cd.130] Servo parameter write request", set the change value to high-order buffer memory and low-order
buffer memory.
• Buffer memory address
Refer to the following for the buffer memory address in this area.
