Abstract

PURPOSE: To make use of a D/A converter for a numerical controller by enabling it to fulfill D/A conversion of a digital signal consisting of more bits than its own bits, by combining the converter with an amplifier.
CONSTITUTION: A positioning controller is provided with 12-bit D/A converter 12 and amplifier 13. While 16-bit up/down counter 11 has 15-bit representing its count contents (16th bit for a sign bit), converter 12 has only 11-bit where count contents are added. For the purpose, counter 11 is divided into two parts consiting of 11-bit each (some bits are used for both groups) and either group is selected depending upon the count value and applied to converter 12. Then, a digital signal sent from multiplexer 18 is converted 13 into an analog signal, which is amplified 13 and inputted to motor 14. This amplifier 13 has its gain changed in accordance with the selection of multiplexer 18 and applies motor 14 with a voltage equivalent to the count value of counter 11.
