How to change individually the servo parameter after transfer of
servo parameter
The servo parameters can be individually changed from Simple Motion module
with the following axis control data.
Setting item
Servo
Cd.130 parameter
write request
Cd.131 Parameter No. Set the servo parameter to be changed.
Cd.132 Change data
POINT
(1) Both of the servo parameter area (internal memory (nonvolatile) and buffer
memory/internal memory) of Simple Motion module 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
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 Simple Motion module.
Therefore, the changed data are overwritten to the RAM data by turning
the servo amplifier's power supply ON again.
