Control device capable of centrally managing control by grouping a plurality of systems

A control device including a plurality of command analysis units that control a machine having a plurality of axes driven by a motor, a plurality of command execution units that execute a command analyzed by the command analysis units, and a system setting unit that sets by dividing the plurality of axes into a plurality of systems, wherein one axis or a plurality of axes controlled by one program of the plurality of axes is set as one system, to control the plurality of systems, the control device comprising:

• a system group setting unit that sets two systems or more selected from the plurality of systems as one system group based on a parameter setting;
• a master system selection unit that selects one system from the system group as a master system to be a reference of operation and classifies other systems of the system group as a slave system group based on a parameter setting;
• a control information storage unit that stores the program needed for control of the master system and control data including a signal and a parameter related to the control of the program as master control information;
• and
• a synchronization unit that controls the operation of the slave system group so as to be synchronized with the operation of the master system by referring to a program command, a control signal, and a control parameter stored as the master control information for the control of the slave system group.
