Abstract
A multi-axis motor controller is provided wherein connectors made to common specifications are provided on a multi-drive control unit of a motor drive control section operated by DC power received from a power supply unit, servo amplifier units and an interface unit. The connectors made to common specifications are used to interconnect the units by local bus cables and enable signals to be sent and received by serial transmission as desired among the units. This architecture simplifies the electrical interconnection among the units and lowers cost without sacrificing freedom of unit layout.
Claims12
A multi-axis motor controller including at least one power supply section that converts AC power supplied form an exterior source to DC power, and a motor drive control section connected to a host controller, said motor drive control section being equipped with multiple units each performing a different control function and housed in a separate case and converts the DC power to AC control power for controlling driving of motors associated with different axes, the multi-axis motor controller comprising generic connectors provided on the units of the motor drive control section and identically configured local bus cables electrically interconnecting the units through the generic connectors to enable sending and receiving of required signals among the units through the local bus cables, said generic connectors and identically configured local bus cables providing for interchangeability between said multiple units.
