Abstract
A manufacturing system 10 is configured to include a driving device 4 configured to drive a manufacturing machine 5 in a step pertaining to product manufacture in a predetermined production management system, the driving device 4 driving the manufacturing machine 5 in the step in response to predetermined information obtained related to a state of the step.
Claims7
A manufacturing system comprising:
- a manufacturing execution system (MES) configured to manage each of a series of manufacturing steps based on a target value;
- a sensor coupled to a jig;
- an electric motor configured to drive the jig to manufacture a product in at least two steps;
- an inverter that controls the electric motor;
- and
- a lower system connected to the MES and the inverter,
- wherein the MES provides, to the lower system, a lower target value that is information in response to driving details of the electric motor to achieve the target value of a step of the series of manufacturing steps based on step result information related to the step,
- wherein the lower system provides, to the inverter, driving target information that is information that has the same content as the lower target value,
- wherein the inverter obtains the step result information related to the step and identifies a command value that is information of driving details of the electric motor to achieve the driving target according to the target value of the step based on the step result information to drive the electric motor.
6 more elements
A manufacturing method comprising:
- providing, by a manufacturing execution system (MES), to a lower system, a lower target value that is information in response to driving details of an electric motor to achieve the target value of a step of the series of manufacturing steps based on step result information related to the step,
- providing, by the lower system, to the inverter, driving target information that is information that has the same content as the lower target value,
- obtaining, by the inverter, the step result information related to the step and identifying a command value that is information of driving details of the electric motor to achieve the driving target according to the target value of the step based on the step result information to drive the electric motor.
