An embodiment includes a plurality of transport modules forming a transport path on which a carriage that transports a workpiece travels, and a control unit that controls a position of the carriage on the plurality of transport modules based on a drive instruction, and the control unit corrects the drive instruction during carriage motion that is based on the drive instruction and stops the carriage.

Transport system and manufacturing method of article

An embodiment includes a plurality of transport modules forming a transport path on which a carriage travels and a plurality of control units each provided to corresponding one of the plurality of transport modules and configured to perform position control of the carriage in accordance with a pre-stored drive condition and a control start timing, and one of the plurality of control units which corresponds to a first transport module that is one of the plurality of transport modules corrects the drive condition by using a difference between an entry timing at which the carriage enters the first transport module and the control start timing.

Transport system, control method, processing system, and manufacturing method of article

A linear motor control apparatus has: a plurality of coil units; a plurality of position detecting units for detecting positions of a plurality of trucks which move over the plurality of coil units; a plurality of deviation calculating units for operating deviation information as differences between the detected truck positions and a target position of the detected truck; a plurality of position control units for operating current control signals based on the deviation information; a plurality of current control units for supplying driving currents to the coil units based on the current control signals; and a switching unit for switching the position control units to which the deviation information is transmitted or switching the current control units to which the current control signals are transmitted.

Linear motor control apparatus and linear motor control system

A transfer system according to an aspect of the invention includes a stator including a plurality of coils, a carriage capable of moving along the stator, a carriage drive magnet provided on the carriage and configured to drive the carriage by magnetic force generated by the plurality of coils, and a power receiver provided on the carriage and including a power receiving magnet configured to drive an actuator by magnetic force generated by the plurality of coils.

Transfer system

A linear motor control apparatus includes a plurality of coil units which are continuously arranged, a plurality of position detecting units configured to detect positions of a first truck and a second truck which move over the plurality of coil units, and a first deviation calculating unit configured to arithmetically operate deviation information as differences between values of the plurality of position detecting units and a target position. In addition, a first position control unit arithmetically operates current control signals on the basis of the deviation information, a first current control unit supplies driving currents to the plurality of coil units on the basis of the current control signals, and a switching unit outputs the values of the plurality of position detecting units for the first truck to the first position control unit and outputs the values of the plurality of position detecting units for the second truck to a second position control unit.
