PURPOSE:To enable the titled device to perform continuous and smooth moving operation by commanding the position of the succeeding interpolarting point in response to any one of CLOCK and NULL signals, which is sent more quickly from the device. CONSTITUTION:An automatic welding equipment is described for example. Current is supplied from a welding electric power source 200 to a torch 109. A control box 400 and a welding controller 300 automatically controls normal revolution, reversed revolution, moving speed, welding current, etc. of each power means on the basis of a program. A CPU in the welding controller 300 operates positions of 2 successive interpolating points and sends a positional demand to an automatic welding equipment 100. The CPU operates the position of the succeeding interpolating point in response to a CLOCK or NULL signal sent from a servo system of the automatic welding equipment 100. |
