PURPOSE:To simplify the hardware-like constitution of an interface, by improving the interface of a controller to be synchronized with rotation of a main spindle motor. CONSTITUTION:A servo-amplifier 11, controlling a feed motor 5, provides a register 13, storing a unit step of instruction data through an interface circuit 12 from a controller 7, and a Zp signal processing circuit 14 inputting one revolution signal Zp from a rotary encoder 9 of a main spindle motor 8. Programming action, for instance, performing torque control in the servo-amplifier 11 can be started by the signal Zp from the controller 7, and constitution of the servo- amplifier 11 or the like is simplified because an interface with the controller 7 is performed in a software-like manner. |
