6.7 Operation Sequence
This section describes outline of the operation sequence. Refer to 6.3 Main Commands and 6.4 Subcommands
for details of command functions and settings.
6.7.1 Operation Sequence for Managing Parameters Using a Controller
When the parameters are managed by a controller, the parameters are transmitted to a controller when the power
is turned ON.
With this operation sequence, the settings of the SERVOPACK do not need to be changed when the
SERVOPACK is replaced. The following table shows the procedure.
* If communication disconnects normally, the NOP command is sent. If communication does not
disconnect normally, the DISCONNECT command is sent for two or more communications cycles
prior to connection, then the CONNECT command is sent.
