Filed: 1991-01-31
Abstract: PURPOSE:To obtain an industrial robot controller which can continue the rotational movements in a single direction with no limitation given to the rotational frequency of an auxiliary axis and also can surely perform the one-round welding with the satisfactorily high working efficiency. CONSTITUTION:A deciding means is provided to detect a fact that the count value of a counter 13 which counts up with the pulse produced in response to the relative position change of an auxiliary axis 6 has reached a reference decision level set previously.
