Title: MULTI-AXIS DRIVER, DIGITAL CONTROL SYSTEM AND MULTI-AXIS ROBOT
Abstract:
A multi-axis driver, a digital control system and a multi-axis robot. The multi-axis driver comprises: a PCI eXtensions for Instrumentation (PXI) power-supply backplane (11), and a control unit (12), a power conversion unit (13) and at least two single-axis inverter units (14), which are mounted on the PXI power-supply backplane (11); the power conversion unit (13) converts an alternating current into a direct current and supplies the same to the at least two single-axis inverter units (14) by means of the PXI power-supply backplane (11); the control unit (12) controls a single-axis inverter unit (14) by means of the PXI power-supply backplane (11) so that the single-axis inverter unit (14) inversely outputs the direct current. By means of the foregoing manner, utilizing the PXI power-supply backplane (11) to mount the control unit (12), the power conversion unit (13) and the at least two single-axis inverter units (14) respectively, the PXI power-supply backplane (11) may be used as a control and power-supplying carrier such that the at least two single-axis inverter units (14) jointly use the control unit (12) and the power conversion unit (13), thereby achieving resource sharing, simplifying the circuit structure, and reducing costs.
