Abstract: PURPOSE:To perform the control with a high reliability against various error patterns by reading absolute position data again at the time when the speed and the acceleration obtained in accordance with differences of absolute position data from an absolute value encoder exceed upper limit values. CONSTITUTION:A first-order difference computing element 4 and a second-order difference computing element 5 calculate the difference of first order and that of second order of absolute position data read from an absolute value encoder 2 any time. Comparators 6 and 7 compare these differences with prescribed upper limit values. Unless both differences exceed the upper limit values, a servo computing element 11 obtains a control signal based on data. If at least one difference exceeds the upper limit value, a retry means 111 causes a data receiver 3 to read data of the present servo operation period again, and the read operation is repeated until such data is obtained that both differences do not exceed the upper limit values. A retry counter 2 generates an error signal when the frequency in repeat exceeds the value of a retry frequency set register 12.

Title: Line equalizing system

Abstract: PURPOSE:To reduce the constitution of a circuit, and also, to decrease the fault rate by providing a level detecting part, a deciding part, a line equalization adjusting part and an identifying part, bringing automatically an input signal to the identifying circuit to optimum correction and sending it out. CONSTITUTION:As for an input signal 2 inputted to a terminal 1, a line loss is generated due to a signal speed, etc., and its level is varied. A level detecting part 3 detects the level of the signal 2 and outputs a level result signal 4 to a deciding part 5. The deciding part 5 does not cause a malfunction by some level fluctuation since it has a hysteresis characteristic, and outputs a line equalization value deciding signal 6 to a line equalization adjusting part 7. The adjusting part 7 adjusts a line equalization value of the signal 2 and outputs a line equalizing signal 8 to an identifying circuit 9. The circuit 9 compares the inputted signal 8 and a constant reference voltage, but since the signal 8 is adjusted by the adjusting part 7, even if an input data level is varied due to a line loss, it is identified without causing a read error, and a contents processing signal 10 is outputted. In such a way, an optimum correction of the input signal is automatized, and the reduction of the constitution and the decrease of a fault rate can be executed.
