This control device is connected to a master device and controls a drive target on the basis of the content of communication with the master device, and includes a communication unit which periodically transmits to and receives from the master device first information, which is information relating to control of the drive target, and second information, which is information relating to safety; a first processing unit which controls the drive target by processing the first information; a second processing unit which, by processing the second information, performs processing to ensure safety of the drive target; and an abnormality determining unit which determines that an abnormality has occurred if both the first information and the second information have not been processed within a prescribed period.

Control device, control method and recording medium

A temperature monitoring device of the present invention includes: a current value acquisition portion () that acquires a current value supplied for the motor; a calorific value inference portion () that infers a calorific value through a first thermal model indicating a relationship between the current value and a calorific value of a servo driver (); and an anomaly judgment portion () that compares the calorific value with a threshold, so as to judge whether there is heating anomaly.

Temperature monitoring device, temperature monitoring method, information processing program and recording medium

The present invention can stabilize driving of a motor even if multiple control instructions of driving the motor are acquired through non-real-time communication. A servo driver () does not perform processing corresponding to other control commands when acquiring the other control commands from other interfaces through non-real-time communication in a process of performing processing corresponding to a control command acquired via one interface and through non-real-time communication.

Motor control device, control method, information processing program and recording medium

When a motor replacement detection portion () detects replacement of a motor (M), a control portion () of the motor control apparatus executes limiting processing for limiting action of the motor (M), at least until an acceptance portion () accepts an input of confirmation information from a user.

Motor control apparatus, motor control method, information processing program, and recording medium

The invention relates to a motor control device, a control method, an information processing program and a recording medium, even though the network for receiving an output permission signal is not connected, the test run of the motor can be safely performed. Even though a signal generating element () of a servo driver () does not receive the output permission signal through a field network (), if the connection to the field network () is determined to be not required, the signal generating element () does not generate the safety command.

Motor control device and control method, information processing program and recording medium

A slave device is realized that establishes a link with a master device or another slave device such that a large link delay hardly occurs. The slave device includes a PHY unit, a COM unit, and a MPU unit. The PHY unit starts an operation according to the specification of the AutoMDI/MDI-X function when the slave device is turned on or the PHY unit itself is reset. After a predetermined time period has elapsed, the MPU unit resets the COM unit, and the PHY unit is reset in response to the reset of the COM unit.

Communication device and link establishment method

Delay in establishing communication is suppressed in a network system including a master device and a slave device. Provided is a setting method for performing communication setting for at least one of a master device and a slave device serving as a target device, the method including a storage step of storing a value of a communication parameter in a state in which the target device has established communication, and a setting step of, in communication setting in a preparatory stage for the target device to start communication, setting the value of the communication parameter that was stored in the storage step.
