Title: Position coder type fixed position stop control circuit
Inventor: HIROTA MITSUHIKO
IPC: B23Q15/26
Filed: 1990-11-30
Abstract: PURPOSE:To improve stop accuracy by increasing the interpolation number of pulses which are outputted by dividing and interpolating the signal of a sensor for detecting the rotational position of a main shaft at specific phase intervals when the main shaft is stopped at a. specific position. CONSTITUTION:An A-phase and a B-phase sine wave signal which are outputted by the sensor 5 of a rotational position detector 1 are converted by A/D converters 6 and 7 into digital signals. An N-multiplying circuit 2 has tables T1 and T2 in a ROM 8 stored with interpolation data (rotational angle in one cycle) in one cycle of the sine waves. One of the tables is selected with the select signal SEL from a position coder system fixed position stop circuit 3. When the table T1 is used, an interpolation signal generated by dividing one cycle of the sine wave into four is obtained and when the table T2 is used, an interpolation signal generated by dividing one cycle into eight is obtained. At the fixed position stop, the table T2 which is larger in the number of interpolation divisions is selected. Consequently, the resolution is improved and the stop position accuracy can be improved without varying the number of pulses generated by the rotational position detector in one turn.
