Multi-axis driver control method, multi-axis driver and multi-axis drive control system having the same
First Claim
1. 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.

Abstract
In the multi-axis driver control method for transmitting a command from an external device to the drive-axis basis controller of the multi-axis driver to set operation and/or parameters of the drive-axis basis controller, the external device is connected to the multi-axis driver on a one-to-one basis, and the external interface is connected to the drive-axis basis controller via a multi-dropped connecting portion. The drive-axis basis controller determines whether the command is self-addressed or not and, if the command is self-addressed, the drive-axis basis controller executes the command and transmits response data corresponding to the command and a transmission permission flag to the multi-dropped connecting portion. The multi-dropped connecting portion opens a transmission port in response to the transmission permission flag and transmits the response data to the external device, and after transmission is finished, the multi-dropped connecting portion closes the transmission port.

4. A multi-axis driver for performing drive-axis basis control, comprising:
-
a one-to-one external interface for external connection; a first communication controller that is connected to the external interface and is capable of multi-dropped connection thereunder; a second communication controller that is connected to the first communication controller on a drive-axis basis, has an identical communication protocol to a communication protocol of the first communication controller and has an opening and closing unit of a transmission port; and a plurality of drive-axis basis controllers that is connected to the second communication controller on the drive-axis basis and configured to execute drive control on the drive-axis basis, each of the drive-axis controllers having a command executing unit that has a unique identification number and is configured to receive and execute a command transmitted with the unique identification number from an external device connected to the external interface of the multi-axis driver, and a unit for, after execution of the command, transmitting response data corresponding to the command and a transmission permission flag that requests the second communication controller to open the transmission port so as to transmit the response data to the external device. - View Dependent Claims (5)

6. A multi-axis drive control system comprising:
-
a plurality of actuators driven on a drive-axis basis; an inverter for supplying power to the actuators; a multi-axis driver for controlling the power of the inverter on the drive-axis basis, the multi-axis driver having a one-to-one external interface for external connection;
a first communication controller that is connected to the external interface and is capable of multi-dropped connection thereunder;
a second communication controller that is connected to the first communication controller on a drive-axis basis, has an identical communication protocol to a communication protocol of the first communication controller and has an opening and closing unit of a transmission port; and
a plurality of drive-axis basis controllers that is connected to the second communication controller on the drive-axis basis and configured to execute drive control on the drive-axis basis, each of the drive-axis controllers having a command executing unit that has a unique identification number and is configured to receive and execute a command transmitted with the unique identification number from an external device connected to the external interface of the multi-axis driver, and a unit for, after execution of the command, transmitting response data corresponding to the command and a transmission permission flag that requests the second communication controller to open the transmission port so as to transmit the response data to the external device; andthe external device configured to set operation and/or parameters of the multi-axis driver.
