Abstract
A multi-axis motor driving apparatus includes: a plurality of drivers individually connected to corresponding ones of the plurality of motors, for supplying electric power to the corresponding ones of the plurality of motors for driving; and an integrated controller for sequentially supplying electric power to the plurality of motors via the plurality of drivers, and based on detection signals of the encoders, determining for each driver whether or not there is miswiring of at least either of a motor wire that connects one of the plurality of drivers to one of the plurality of motors or a detector wire from the encoder.
Claims12
A multi-axis motor driving system, comprising:
- a plurality of motors, each comprising a position detector;
- a host control device for outputting a motor control command;
- and
- a multi-axis motor driving apparatus for driving the plurality of motors based on the motor control command,
- wherein the multi-axis motor driving apparatus comprises:
- a plurality of drivers individually connected to ones of the plurality of motors corresponding thereto, for supplying electric power to ones of the plurality of motors corresponding thereto for driving;
- and
- a controller for sequentially supplying electric power to the plurality of motors via the plurality of drivers, and based on detection signals of the position detectors, determines for each driver whether or not there is miswiring of at least either of a motor wire that connects one of the plurality of drivers to one of the plurality of motors or a detector wire from one of a plurality of the position detector.
