Servo Parameter Management

Transmission of servo parameters

The Motion CPU stores servo parameters as a file, extracts them to the internal servo parameter open area (backup memory),
and then communicates with the servo amplifier. The servo parameter storage area, and transfer timing is shown below.

*1 The sensing module cannot write/read servo parameters by direct connection to MR Configurator2.
*2 The sensing module cannot write/read servo parameters via GOT(Motion monitor).
Managed servo parameters
Servo parameters managed by the Motion CPU are first extracted to the servo parameter open area, and are then
automatically transferred to the servo amplifier/sensing module when performing initial communication.
If changes are made to the content of the servo parameter file, use the following procedure to update the
changed content to the servo amplifier/sensing module.
• Turn OFF or reset the Multiple CPU system.
• Turn the "[Rq.1120] PLC ready flag (R: M30000/Q: M2000)" from OFF to ON (or, "File transfer flag
(SD820)"), and then turn ON the servo amplifier/sensing module control power supply again, or disconnect
and then reconnect SSCNET communication.
If changes are also made to servo parameters for which it is necessary to reboot the servo amplifier control
circuit power supply, it is first necessary to perform the procedure above, and then reboot the servo amplifier/
sensing module control circuit power supply again.
