Abstract
A control device includes: an output unit configured to select a motor and output a drive command to a motor drive unit that should be connected to the selected motor so that the selected motor executes a predetermined feed operation; an acquisition unit configured to acquire feedback information from each of the multiple motor drive units; and a wire connection determination unit configured to determine, based on the feedback information, whether the selected motor is connected to the motor drive unit that should be connected to the selected motor, by a power line and a feedback line.
Claims13
A control device that controls a plurality of motors installed in a machine tool or an industrial machine through a plurality of motor drive units, wherein:
- the plurality of motor drive units are connected to the plurality of motors by multiple power lines and multiple feedback lines;
- the motor drive unit supplies the motor with electric power according to a drive command from the control device, through the power line;
- and
- the motor transmits feedback information corresponding to current positional information, to the motor drive unit through the feedback line,
- the control device comprising:
- an output unit configured to select at least one of the plurality of motors and output the drive command to the motor drive unit that should be connected to the selected motor so that the selected motor executes a predetermined feed operation;
- an acquisition unit configured to acquire the feedback information from each of the plurality of motor drive units;
- and
- a wire connection determination unit configured to determine, based on the feedback information, whether the selected motor is connected to the motor drive unit that should be connected to the selected motor, by the power line and the feedback line according to a prescribed connection relationship.
A wire connection determination method in which a plurality of motor drive units and a plurality of motors installed in a machine tool or an industrial machine are connected to each other by multiple power lines and multiple feedback lines, the motor drive unit supplies the motor with electric power according to a drive command, through the power line, and when the motor transmits feedback information corresponding to current positional information, to the motor drive unit through the feedback line, it is determined whether the multiple power lines and the multiple feedback lines are connected according to a prescribed connection relationship,
- the wire connection determination method, comprising:
- a selecting step of selecting at least one of the plurality of motors;
- an output step of outputting the drive command to the motor drive unit that should be connected to the selected motor so that the selected motor executes a predetermined feed operation;
- an acquisition step of acquiring the feedback information from each of the plurality of motor drive units;
- and
- a wire connection determination step of determining, based on the feedback information, whether the selected motor is connected to the motor drive unit that should be connected to the selected motor, by the power line and the feedback line.
