Abstract

PURPOSE: To detect the present location of a movable portion of a numerical value controller, by counting control pulse by generating the control pulse so that the content of an error register may become zero in response to the content when said movable portion is driven regardless of the output of the error register.
CONSTITUTION: A numerical value controller is divided into a numerical value control portion NCP and a location control unit. Numerical value commands are transmitted to a pulse generator PG through a tape reader TR and a control circuit CC, and the directions corresponding to command values and the command pulse of the number are generated here. Command pulse is counted at an error register ER, the value is converted into voltage proportional to the value at a gate G and a converter CON 1, and a motor M1 is driven to displace a machine movable portion MP. A detector DET detects the content of the error register ER, and transmits signals, which show whether or not the content is positive, negative or zero, to the control portion NCP, and a numerical value generating circuit CNG is mounted into the control portion NCP
