    摘要： A tool spindle is driven by a motor and is connected to an angle of rotation transmitter. The signal of the transmitter connected to the tool spindle represents the desired value for the drive of a work piece spindle. The angle of rotation of the workpiece spindle is measured with another transmitter. A control deviation signal which is fed into a servo amplifier of the workpiece spindle drive via a controller is formed from both transmitter signals. A variable observer circuit into which the control deviation signal is also fed is arranged in parallel to the controller. The control deviation signal is stored sequentially in several sample and hold circuits by means of a multiplexer circuit during one tool revolution. The content of each sample and hold circuit is integrated by means of a respective integrator. During the following cycle, a correction signal, which is added to the output signal of the controller, is formed by sequential interrogation of the integrators by means of a demultiplexer circuit. The multiplexer and demultiplexer circuits are controlled by a synchronizing circuit which is synchronized by an index signal.

    摘要： There are provided a position and velocity control system for producing a velocity command signal in response to a position command signal and a signal representing a current position and velocity of a servo motor, a current control system for supplying a drive current to the servo motor in response to the velocity command signal, and a communication system for transmitting data between the two systems by means of a bilateral communication line. A servo control system is thereby separated between the current control system and the position and velocity control system and connected to each other through the communication system. This separation through the communication system is advantageous for protecting the position and velocity control system from influence of noise generated in the current control system and also brings about benefits such as expansion of the controllability owing to the bilateral communication, sharing of a single current control system by plural servo motors by switching connection of the servo motors and controllability of plural pairs of servo motor and current control system by a single position and velocity control system by a multi-point connection.

    摘要： A multiplexing circuit which rapidly shares a single rate generator among up to 16 different motors. The circuit utilizes an addend memory block with n-bit by m-deep memory structures. Each memory address represents a particular stepper motor in the system. An axis scanning state machine 9 drives the memory structure address lines in a circuitous manner. At each memory address visit, the state of the circuit is re-established based on information stored from the last visit. The addition operation is performed to change the accumulator value in memory block 102. Any possible edge event is noted by edge detector 11. An edge produces a step and position monitor count. The axis-scanning state machine then moves on to the next address representing the next motor. The axis-scanning memory address influences memory structures throughout the device including accumulator value in memory block 102, addend memory values 12, device configuration 13, and step monitor counter 14. The complete axis-scanning cycle frequency of N Hz supports step rates of N Hz.

The system further includes a servo output module for generating commands to drive associated motors on each of the axes of the machine tool and a transducer module which provides feedback information from these machine axes. In addition, the system further includes an input signal and an output signal module that are used to indicate and/or command the various states or modes of operation of the machine.
