An electromagnetic brake controller for controlling a negative-actuated electromagnetic brake includes an output terminal connectable to the electromagnetic brake and a brake control section that outputs, through the output terminal, a brake control signal to be provided to the electromagnetic brake. The brake control section outputs a brake control signal for releasing the electromagnetic brake in response to a normal brake command and a safety brake command both indicating ON and outputs a brake control signal for applying the electromagnetic brake in response to at least one of the normal brake command or the safety brake command indicating OFF. The electromagnetic brake controller performs both safety control and normal control over the electromagnetic brake connected to the output terminal.

Electromagnetic brake control device and control device

A control system for monitoring a control state of a target device that receives drive control by a motor includes a setting unit that sets an origin for position monitoring of the target device and a sensor that detects the target device reaching a predetermined position. The setting unit includes an obtainer that obtains, under predetermined drive control over the target device by the motor, leading and trailing edges in a detection signal from the sensor in response to the target device reaching the predetermined position, and a calculator that calculates the origin using first position information associated with a target device position and calculated based on the leading and trailing edges in the detection signal and second position information associated with the target device position and different from the first position information.

Control system for monitoring control state of target device

Provided is a motor control device comprising a motor control unit and a safety monitoring unit. The motor control unit switches a rotation direction of a motor with respect to an input instruction in accordance with a set motor-control rotation-direction specified value. The safety monitoring unit monitors, on the basis of a position or speed of the motor, a state of the motor deviating from any one of a plurality of safety state conditions prescribed by a plurality of set safety-monitoring parameter values, and the safety monitoring unit can treat the plurality of safety-monitoring parameter values as a value of a case when the rotation direction of the motor is a first direction or as a value of a case when the rotation direction of the motor is a second direction reverse to the first direction. The motor control device has a safety function being flexible in programming.

Motor control device and programming device

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.
