Abstract: A motor control device includes: a first communication unit that transmits or receives data to or from a motor; a communication disconnection determination unit that determines that the motor and the motor control device are in a disconnection state based on a fact that there is no reply from the motor within a prescribed period, and that determines that the motor and the motor control device have been restored to a connection state based on a fact that a reply from the motor to the motor control device has been restarted; and a replacement determination unit that obtains identification information from an identification information storage of the motor via the first communication unit and determines that the motor has been replaced, when it is determined that the motor and the motor control device have been restored to the connection state.

Abstract: A communication device includes a processor and a communication part. The communication part communicates with one or more slaves. The processor has a function of executing communication processing and setting processing. The communication processing includes causing the communication part to transmit a frame including main data to the one or more slaves in a first period. The setting processing includes setting N (N is an integer of 2 or more) second periods within the first period. The setting processing includes setting a slot for performing communication of sub-data other than the main data for each of the second periods. The frame includes at least one of the slots during a transmission period of the main data.

Abstract: A motor-driving apparatus, which drives a motor while controlling the motor based on an external command signal from an external device, includes an external command processor, a program storage, a motor controller, a program rewriting unit, a rewriting data input terminal. The external command processor outputs a motor control command from the external command signal based on an external command processing program. The motor controller controls an operation of the motor according to the motor control command based on a motor control program. Further, the external command processing program and the motor control program are previously stored in the program storage. The program rewriting unit rewrites only the external command processing program stored in the program storage based on the program rewriting data received from the rewriting data input terminal.

Abstract: A motor control device includes an instruction position detector that calculates, as an instruction position detection value, a position detection value at an external instruction timing. The instruction position detector includes an internal counter, a detection position calculator, and a correction value generator. The internal counter outputs a count value counted at a cyclic interval shorter than a position read cycle that is an interval at which a motor position detected by a rotary encoder mounted on a motor is read as a position detection value. The detection position calculator controls a rotation of the motor by use of the position detection value, is supplied with an external detection instruction signal including an instruction pulse, and calculates the instruction position detection value by use of a count value at the external instruction timing indicated by an edge of the instruction pulse. The correction value generator includes an external input terminal, an input circuit, a count value acquisition unit, and a correction value calculator.

Abstract: In a motor control system, a plurality of motor control devices for controlling motors and a controller are connected to each other via a communication line. The controller generates a communication signal including an operation command, and transmits the communication signal to the respective motor control devices in a predetermined communication cycle. The plurality of motor control devices includes two motor control devices in a first group and a motor control device in a second group. Each of the motor control devices in the first group includes a data transceiver, a motor controller, a corrector, and a synchronous timing generator. The data transceiver receives an operation command issued to the motor control device, and receives operation information in the motor control device in the second group. Based on the operation command, the motor controller generates a torque command signal for controlling the motor. The corrector generates a torque correction signal based on the operation information, and corrects the torque command signal. The synchronous timing generator generates a timing signal that matches pieces of process timing of the motor controllers in the first group with each other.
