PURPOSE:To give commands to plural control subjects of the same system with a single address code by giving the commands of the same type to the corresponding motors through a distribution memory for commands of the same type in response to the spindle number of each motor. CONSTITUTION:The new number of rotation commands (of the same type), i.e., S1 = 5000, S2 = 4000 and S3 = 3000 which are read out of a working program memory 4 by a single address code S to three spindles are analyzed by an arithmetic part 3 of a numerical controller 2 and supplied to a distribution memory 8 for commands of the same type to be stored in each memory position corresponding to the designated spindle number. At the same time, the drive signal of 5000rpm is delivered to a motor 71 for the 1st spindle from the memory 8 via a machine I/F 6 together with the drive signals of 4000rpm and 3000rpm delivered to motors 72 and 73 for drive the 2nd and 3rd spindles respectively. Then these motors 71 - 73 are driven by each designated number of rotation. While an idle address code B is available to other purposes of application.
