4.7.1
Operation Sequence for Managing Parameters Using a Controller
The following describes the operation sequence for managing parameters using a controller.
The controller manages the necessary parameters, and transfers them when the power is
turned ON. With this operation sequence, the settings can be managed by the controller even
when the SERVOPACK is replaced.
* 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.
