摘要： A control system for controlling an industrial robot and a method thereof. A control unit generates a control signal for controlling the motor. At least one drive unit controls the motor. The drive unit includes a switching unit adapted to convert DC current to alternating current to the motor in dependence on the control signal. A safety unit generates a stop signal for stopping the robot upon occurrence of a safety event. The drive unit disables the switching unit upon receiving the stop signal. The safety unit generates the stop signal with a time delay with respect to the safety event. The control unit generates the control signal in such a way that the motor is electrically braked during the time delay. The control system transfers the stop signal to the brake, which mechanically brakes the motor upon receiving the stop signal, and delays the stop signal to the drive unit so that the brake receives the stop signal before the drive unit to ensure that the mechanical brake is applied before the switching unit is disabled.

摘要： A method for controlling a manipulator system including a manipulator, several drives and a mobile platform. A first converter for actuating at least two of the several drives is associated with the manipulator system. The method includes the steps of: a) identifying one of the drives of the manipulator system that is associated with the first converter and that must be used to travel over a current planned movement path of the manipulator system, and (b) actuating the one identified associated drive by means of the first converter, where the actuated drive is for the manipulator system to travel over the planned movement path. One of the at least two drives that is not being actuated is stationary preferably fixed or secured by a mechanical brake.

摘要： A polyphase induction motor is driven from an inverter having a set of switches activated in prescribed on-off patterns to provide forward and reverse voltage vectors and a zero vector for controllably energizing the motor. Memories are provided on which there are written forward voltage vector data for forwardly energizing the motor, reverse voltage vector data for reversely energizing the motor, and zero vector data for de-energizing the motor. The voltage vector data and zero vector data are selectively read out from the memories in order to cause the inverter to generate in real time the corresponding voltage vectors and zero vectors needed for the motor to be quickly revolved to, and set out of rotation exactly in, a desired angular position. For such optimum motor speed control an ideal control curve is predefined which represents the ideal relationship between the motor speed and the difference between the actual and the desired angular position of the motor. The voltage vector data and zero vector data are read out from the memories so that an actual control curve representative of the actual relationship between the motor speed and the difference between the actual and the desired angular position may approximate the ideal control curve as closely as possible.

摘要： Control circuitry of a motor drive provides commands for operation of power circuitry in cooperation with peripheral circuits and devices, such as converters, inverters, feedback precharge circuits, feedback devices, interfaces, and so forth. The communications with the devices is handled by fiber optic communications circuitry that implements a flexible scheme of dynamic interval communication depending upon the capabilities and design of the peripheral circuit or device. The communication may be in accordance with a plurality of predetermined schemes, each having different data transfer rates, data allocations, and so forth. The schemes may each set communications protocols (e.g., timing) over a high speed interface between the fiber optic communications circuitry on one side and over fiber optic cables to the peripherals on another side.

摘要： A motor driving apparatus capable of drivingly controlling a plurality of inverter units with a single motor driving command from a motor control unit, and thereby control a large-capacity motor or the like. The motor control unit sends out a single motor driving command (torque command) S. An intermediary unit obtains motor driving commands S×A1 to S×A4 for the inverter units by multiplying the motor driving command S by each of coefficients A1 to A4 set in advance. The inverter units are fed with the motor driving commands S×A1 to S×A4 individually and drive a single motor. Since the motor is driven by the total current supplied by the inverter units, the motor can generate a large torque. The motor control unit only needs to generate a single motor driving command S, and hence only needs to operate a single processing part. Hence, the motor control unit can generate and send out motor driving commands for other motors to drive them.
摘要翻译：一种电动机驱动装置，其能够通过来自电动机控制单元的单个电动机驱动指令来驱动地控制多个逆变器单元，从而控制大容量电动机等。电机控制单元发出单个电动机驱动指令（转矩指令）S.中间单元通过将电动机驱动指令S乘以系数A 1至A 4中的每一个来获得用于逆变器单元的电动机驱动指令SxA 1至SxA 4 提前。逆变器单元分别供给电动机驱动指令SxA 1〜SxA 4，驱动单个电动机。由于电动机由逆变器单元提供的总电流驱动，电动机可以产生大的转矩。电机控制单元仅需要生成单个电机驱动指令S，因此仅需要操作单个处理部件。因此，电动机控制单元可以生成并发送用于其他电动机的电机驱动命令来驱动它们。
