摘要： A servo amplifier including an encoder for detecting rotation of a servomotor (11), a servo amplifier (13) for performing feedback control of the rotation of the servomotor based on a count value (hereinafter referred to as an "encoder value") of the encoder, and an amp control section (17) for controlling operation of the servo amplifier, wherein the amp control section sends an initialization instruction for initializing the encoder to the servo amplifier in a state of fixed cycle connection over a servo network between the servo amplifier and the encoder when an error occurs with the encoder. The servo amplifier performs initialization of the encoder without disconnecting the servo network when receiving the initialization instruction sent from the amp control section.

摘要： The position of the moving mirror (20) in a Fourier-transform infrared spectrometer is monitored with a circuit which has an incremental counter formed of a plurality of cascaded up/down counters (82, 84, and 86) that count the pulses received by a laser detector (42) to yield a relative position count. A microprocessor (100) maintains an absolute position count by reading the counters (82, 84, and 86) and updating its absolute position count at regular intervals. A portion of the circuit is dedicated to discriminating the direction of the moving mirror (20) by gating circuitry connected to the digitized output of the laser detectors (42, 44).

摘要： Bei einer derartigen Positionsmeßeinrichtung zum Messen der Relativlage zweier Objekte wird die Teilung (WTa) eines mit dem einen Objekt verbundenen Teilungsträger (TTa) von zwei mit dem anderen Objekt verbundenen Abtasteinheiten (AE1a, AE2a) zur Bildung zweier Abtaststellen abgetastet. Die jeweils von den beiden Abtasteinheiten (AE1a, AE2a) erzeugten zwei gegeneinander phasenversetzten periodischen Abtastsignale (S1a, S2a, S3a, S4a) können durch Störeinflüsse mit Phasenverschiebungen (+β, -β) gegenüber den geforderten Phasenlagen behaftet sein, die Meßungenauigkeiten nach sich ziehen. Zur Vermeidung derartiger Meßungenauigkeiten werden aus den vier periodischen Abtastsignalen (S1a, S2a, S3a, S4a) in der Auswerteeinrichtung (AWa) mittels Verknüpfungselemente (ADa, STa, SUa) zwei periodische resultierende Signale (RS1a, RS2a) mit der geforderten Phasenlage erzeugt.

摘要： A noise blanking circuit for eliminating evidence of noise present :n an incoming alternating electrical control signal, such as a shaft encoder or tachometer signal in a servo control circuit, is disclosed. The alternating electrical signal is input to a first input (A) of a shift register (44) having a plurality of outputs (C, E, G, J). Clock signals having a preselected frequency are input to a second input (B) of the shift register (44) for digitally sampling the alternating electrical signal at the times of occurrence of the clock signals so as to produce digital samples shiftably stored in respective storage locations of the shift register (44), which are connected to the plurality of outputs (C, E, G, J) of the shift register. The digital samples appearing at predetermined ones of the plurality of outputs (C, E, G, J) of the shift register (44) are input to a logic circuit (50...60) for producing a first logic state (low state) as an output signal, when a first logic state appears at the predetermined ones of the plurality of outputs (C, E, G, J) of the shift register (44), and a second logic state (high state) as the output signal, when a second logic state appears at the predetermined ones of the plurality of outputs (C, E, G, J) of the shift register (44). The selectivity of the noise blanking circuit can be selected by adjusting the clock signal frequency and/or the number of storage locations included in the shift register (44) and/or changing the predetermined ones of the plurality of outputs (C, E, G, J) of the shift register (44) which are input to the logic circuit (50...60).

摘要： A control system in accordance with the invention comprises error signal generating means (23) for generating an error signal (Xe) in response to a reference signal (Xr) and a first and a second position signal (Xpa, Xpb resp.). The reference signal is a measure of the desired value of a position of a first part (5) of a drive system with respect to a second part (0) of the drive system. The position signals (Xpa, Xpb) are a measure of the actual value of said position. The error signal (Xe) is a measure of the difference between the desired value and the actual value of the position. The control system further comprises energizing means (24) for energizing a motor (1) which is to be controlled by the control system in dependence on the error signal (Xe). The control system of the invention is characterized in that the error signal generating means (23) are adapted to generate weighting factors (Xwa, Xwb) from the reference signal (Xr), for weighting the position signals with the weighting factors and determining a sum (Xel) of the weighted position signals. The control system can be used in a recording/playback device for positioning a read/write head.
