Abstract

The invention discloses a disintegrated module-type drive controller based on a silicon controlled rectifier. The drive controller includes a strong current drive module and a weak current integrated control module. The strong current drive module is connected to a numerical control machine ancillary attachment motor. The weak current integrated control module is connected to an external CNC controller. The strong current drive module is provided with a weak current board connection and through connection port thereon. The weak current integrated control module is provided with a strong current board communication port. The strong current board communication port is connected to the weak current board connection and through connection port. According to the invention, the strong current drive module and the weak current integrated control module are separated from each other and are then connected through a relay, which helps to reduce maintenance cost and manufacturing cost of a drive control circuit of a numerical control machine.

Description

technical field [0001] The invention relates to a motor drive controller in the field of automation, in particular to a split modular drive controller for connecting an external CNC controller, a machine tool operation panel and a power device, in particular to a drive controller for connecting an external CNC controller , machine tool operation panel and the split modular drive controller for the accessory motor of the CNC machine tool. Background technique [0002] CNC machine tools are mainly composed of mechanical components and control systems composed of multi-axis and their linkages. The multi-axis and their linkages in the mechanical components are driven by accessory motors. The accessory motor is driven and controlled by the control system to complete the multi-axis linkage action. [0003] The traditional CNC machine tool control system adopts mechanical mode control. Generally, AC contactors such as Schneider, Mitsubishi, and Chint are mainly used. The calculati...
