Patent ID: 8334669

Claim:
A multi-axis driver control method for transmitting a command from an external device to a drive-axis basis controller of a multi-axis driver to set operation and/or parameters of the drive-axis basis controller, comprising the steps of: connecting a one-to-one communication port of the external device to an external interface of the multi-axis driver on a one-to-one basis; connecting the external interface to the drive-axis basis controller via a multi-dropped connecting portion; the multi-dropped connecting portion converting the command into protocol data suitable for multi-dropped connection and transmitting to the data to the drive-axis basis controller; the drive-axis basis controller determining whether the command is self-addressed or not and, if the command is self-addressed, the drive-axis basis controller executing the command and transmitting response data corresponding to the command and a transmission permission flag to the multi-dropped connecting portion; the multi-dropped connecting portion opening a transmission port in response to the transmission permission flag and transmitting the response data to the external device; and after transmission is finished, the multi-dropped connecting portion closing the transmission port.
