Chapter 7 Memory Configuration and Data Process
(1) When the servo amplifier's power supply is turned ON before the system's
power supply ON.
(a) When the servo parameter "
Pr.100
Servo series
" "0" is stored in the
internal memory (nonvolatile).
Communication start timing to the servo amplifier: Initialization completion
(Fig. 7.1 (A))
Transfer the servo parameter : The data stored (backed
up) in the internal
memory (nonvolatile).
0 (Standby)
21 (Servo OFF)
20 (Servo amplifier has not been connected/servo amplifier power OFF)
Transfer the servo parameter at this point to the servo amplifier

(The servo series of internal memory (nonvolatile) is set.)
(b) When the servo parameter "

" = "0" is stored in the
internal memory (nonvolatile).
Communication start timing to the servo amplifier: The data written from
