Abstract
A mechanical equipment control system includes a mechanical apparatus, a load ratio detection circuit, and an integration control circuit. The mechanical apparatus includes a motor which is configured to drive the mechanical apparatus. The load ratio detection circuit is configured to detect a load ratio of the motor. The integration control circuit is configured to control the mechanical apparatus based on an operation parameter while keeping the load ratio in an allowable load state.
Claims19
A mechanical equipment control system comprising:
- mechanical equipment including a plurality of mechanical apparatuses configured to be controlled based on an operation parameter for the mechanical equipment, each of the plurality of mechanical apparatuses comprising:
- a motor which is configured to drive each of the plurality of mechanical apparatuses;
- a motor controller configured to drive the motor;
- and
- a sensor configured to detect a state value of at least one of the motor and the motor controller;
- a load ratio detection circuit configured to calculate, as a load ratio, a motion margin of the at least one of the motor and the motor controller based on the state value;
- and
- an integration control circuit configured to control the plurality of mechanical apparatuses based on the operation parameter for the mechanical equipment while keeping the load ratio in an allowable load state.
A control apparatus for mechanical equipment including a plurality of mechanical apparatuses each having a motor, the control apparatus comprising:
- a motor controller configured to drive the motor;
- a sensor configured to detect a state value of at least one of the motor and the motor controller;
- a load ratio detection circuit configured to calculate, as a load ratio, a motion margin of the at least one of the motor and the motor controller based on the state value;
- and
- an integration control circuit configured to control the plurality of mechanical apparatuses based on the operation parameter for the mechanical equipment while keeping the load ratio in an allowable load state.
A method for controlling mechanical equipment including a plurality of mechanical apparatuses each including at least one motor, the method comprising:
- controlling a motor controller to control the at least one motor to move each of the plurality of mechanical apparatuses of mechanical equipment based on an operation parameter for the mechanical equipment while keeping a load ratio in an allowable load state;
- detecting a state value of at least one of the motor controller and the at least one motor;
- and
- calculating, as the load ratio, a motion margin of the at least one of the motor controller and the at least one motor based on the state value.
