摘要： A communication control system has a plurality of control units that are connected via a communication bus to provide bidirectional communication. A control unit detects a failure when it occurs. Upon failure detection, the control unit generates a failure detection signal which operates a communication signal cutoff means to cut off the communication signal transmission from the control unit. In accordance with the communication signal reception state in a control unit other than the control unit in which the failure is detected, the former control unit identifies a failure occurrence in the latter faulty control unit.

摘要： In such a product that torque of a motor is continuously generated when a rotation number of the motor is nearly equal to zero, since an output voltage is kept at a constant value in accordance with a rotation position of the motor, such a condition that currents are concentrated in a specific element are maintained. As a result, a temperature of the specific element is increased, so that there are problems that a temperature fail of an inverter apparatus may readily occur, and thus, lifetimes of elements are lowered. In a power converter of a motor drive apparatus, windings are energizing-controlled in such a manner that only 1 phase of a switching circuit is pulse-width-controlled when the motor is under motor locking condition.

摘要： In an apparatus using an inverter as a motor drive apparatus, continuous operation can be permitted during a motor open-phase without providing any additional switching element. Especially, in an electric brake apparatus, higher security can be assured. When a motor winding of one phase occurs an open-phase, currents are conducted to the remaining normal phases while taking the position of a rotor of motor into account to thereby generate torque of the motor. Since the motor torque can be generated continuously in the event of a phase malfunction, reliability of apparatus such as the electric brake apparatus can be improved.

摘要： High accuracy is achieved in paper feed control without increasing the size of an encoder, which would result in an increase in cost. The velocity of a paper feeding mechanism is calculated from an edge signal that is generated by the encoder in response to the motion of the paper feeding mechanism. Based on the calculated velocity, a calculation is performed as to the time needed to reach a stop position since a detection of an encoder signal edge immediately before the stop position. Based on the calculated time, a control signal for stopping the paper feeding mechanism is generated.

摘要： When torque of a DC motor is dropped down to zero at a stop position, force is generated by deformation of a member for transmitting the torque of the DC motor. The force moves the driven body which is in the stopped state, which results in a shift of the driven body from the stop position. Therefore, a process for stopping the driven body is performed according to the amount of shift by an encoder which periodically outputs a pulse signal according to movement of the driven body, a unit for acquiring velocity information and position information of the driven body based on the pulse signal, a controlling unit for controlling a moving unit based on the velocity information and the position information, and a unit for calculating the amount of shift, which is caused by the force generated by the deformation of the member for transmitting the torque, at the stop position of the driven body.
