A main circuit power source and a control power source of a motor drive device are backed up. A first backup capacitor is inserted between a rectifier and a control power source output terminal that supplies power to a control circuit of a driver.

Power supply device

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

The disclosure enables mutual relationships among operation statuses of each motor to be ascertained without using synchronous serial communication between multiple motor control devices. The motor control system is equipped with: a motor driver having a trigger determination part for determining whether or not a trigger condition is satisfied, a trigger notification part for transmitting a trigger notification indicating that the trigger condition is satisfied to motor drivers by asynchronous communication, and a trace result information generation part for causing a storage part to store a trigger data number for identifying operation data when the trigger condition is satisfied; and motor drivers each having a trace result information generation part for causing a storage part to store a slave trigger time at which the trigger notification is received, a trigger data number for identifying operation data corresponding to the slave trigger time, and a master trigger time.

Motor control system, motor control device, and non-transitory 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 safety system has higher user design flexibility. Motor controllers () include a motor drive circuit () that outputs a motor voltage command signal for driving motors () in accordance with a motor drive command value, an inverter () that supplies power for driving the motors () by switching based on the motor voltage command signal, a safety control unit that outputs a drive permission signal for driving the motors () in accordance with communication data received through a communication circuit (), a cut-off circuit () that receives the drive permission signal and the voltage drive command signal and cuts off the voltage drive command signal to an inverter () when receiving no drive permission signal, and a safety input unit () that receives redundant safety input signals. The cut-off circuit () receives a logical AND of the safety input signal and the drive permission signal.

Networked motor controller with safety control unit

A safety unit is provided for this purpose, and includes a position determining unit, a speed determining unit, a logical product unit, and a stopping unit. When a rotation amount (positional data) of an encoder rotating in connection with a rotation shaft of a servo motor falls within a predetermined limiting range, the position determining unit outputs a command for stopping a motor to a logical product unit. When rotation speed of the encoder rotating in connection with the rotation shaft of the servo motor falls within a predetermined limiting range, the speed determining unit outputs the command for stopping the motor to the logical product unit. This control by the logical product unit requires a stop command from both the position and speed determining units. The logical product unit informs the stopping unit to stop the servo motor to a controller.

Apparatus for controlling power source

The operation state of a servo motor is monitored and output to a user before automatic termination of power to the motor. A servo system includes a servo motor and a safety unit. The safety unit cuts off electric power to the servo motor when at least one of a speed, a position, acceleration, an amount of movement, a movement direction, and torque of the servo motor is outside a first operation range. Furthermore, the safety unit outputs a warning when at least one of the speed, the position, the acceleration, the amount of movement, the movement direction, the torque is within the first operation range, but is outside a second operation range that is narrower than the first operation range. User controls allow reduced operation when outside the second operation range.

Drive control apparatus

A signal output unit generates an A phase output signal of a rectangular wave and a B phase output signal of a rectangular wave from the A phase sinusoidal wave signal and the B phase sinusoidal wave signal, respectively and outputs the generated signals. An internal signal generating unit (comparator) generates an A phase internal signal of a rectangular wave and a B phase internal signal of a rectangular wave from the A phase sinusoidal wave signal and the B phase sinusoidal wave signal, respectively, which are further processed by counters, and an abnormality detector. Each counter resets in response to a pulse edge of a signal for detection. The abnormality detector detects an abnormality when the count value of at least one of counters reaches a prescribed value.
