Abstract
Detection data of an amount of control is directly monitored and a correction control command is directly outputted by a plurality of numerically controlled drive units 4, 5, 6 via the common sending line 3 and the common receiving line 2 without using NC 1. When a dedicated communication line 30 is used, detection data of an amount of control is directly monitored and a correction control command is directly outputted without using NC 1. The data is processed by the numerically controlled drive units 4, 5, 6 which are controlled and driven at a higher speed than the speed determined by the control cycle of NC 1, and the synchronizing control is carried out.
