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;
- a plurality of connectors individually connected to ones of the plurality of position detectors corresponding thereto, for receiving detection signals output from the plurality of position detectors;
- and
- a controller for determining for each of the plurality of drivers, based on the detection signals received by the plurality of connectors while sequentially supplying electric power to the plurality of motors via the plurality of drivers, whether or not there is miswiring, which is a conflict of a correspondence relation between the plurality of drivers and the plurality of connectors, and one or more of the plurality of connectors corresponding to the miswiring.
