POINT
(1) Both of the servo parameter area (internal memory (nonvolatile) and buffer
memory/internal memory) of QD77MS's and the parameter of servo amplifier
are changed.
(2) When the servo parameters that become valid by turning ON the servo
amplifier's power supply are changed, be sure to turn ON
(Note)
twice the servo
amplifier's power supply after change.
(Note): The servo amplifier's RAM data are changed by parameter setting, but
the servo amplifier's EEPROM data are not changed. The EEPROM
data before the change are overwritten to RAM by the servo amplifier's
power supply ON again, and then the servo amplifier starts.
After that, the changed data are written to the servo amplifier's
EEPROM in an initial communication with QD77MS. Therefore, the
changed data are overwritten to the RAM data by turning the servo
amplifier's power supply ON again.
