■Servo parameter of the buffer memory/internal memory
The followings show details about the operation timing and details at transmitting the servo parameter of the buffer memory/
internal memory.
• When the servo parameter is written in the internal memory (nonvolatile), it is unnecessary to use a setup
from the program/engineering tool.
• Axis connection time varies depending on the number of axes and the servo amplifier's power supply ON
timing. And, time when "20: Servo amplifier has not been connected/servo amplifier power OFF" is set in
"[Md.26] Axis operation status" is also varies.
• When the servo amplifier's power supply is turned ON before the system's power supply ON and the servo parameter
"[Pr.100] Servo series"  "0" is stored in the internal memory (nonvolatile)
