Multi-axis driver control method, multi-axis driver and multi-axis drive control system having the same

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.

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;
• and
• the external device configured to set operation and/or parameters of the multi-axis driver.
