The present disclosure relates to systems and processes for controlling the relative positions or phasing of advancing substrates and/or components in absorbent article converting lines. The systems and methods may utilize feedback from technologies, such as vision systems, sensors, remote input and output stations, and controllers with synchronized embedded clocks to accurately correlate component placement detections and placement control on an absorbent article converting process. The systems and methods may accurately apply the use of precision clock synchronization for both instrumentation and control system devices on a non-deterministic communications network. In turn, the clock synchronized control and instrumentation network may be used to control the substrate position. As such, the controller may be programmed to the relative positions of substrates and components along the converting line without having to account for undeterminable delays.

A numerical controller, which is capable of controlling an output value without causing delay or the like in feedback control, includes an instruction program analysis unit configured to analyze a program instruction and generate instruction data instructing movement of the axis, and a speed computation unit configured to start speed computation processing to compute a feeding speed of the axis by the instruction data or an override for the feeding speed by feedback control such that the spindle load value becomes constant. The speed computation unit is configured to update a feature amount intended for elimination of deviation between a desired value and a feedback value in the feedback control when another override that is different than the override that has been computed is output. The feature amount is updated to a value obtained by back calculation from the other override that is to be output.

A numerical controller looks ahead and analyzes commands indicated by a block contained in a program, and identifies a travel direction of a control target for each of the commands to calculate a time constant based on the identified travel direction. The numerical controller then sets a time constant for filter processing based on the time constant for each of the commands, and performs filter processing on command data subjected to a linear acceleration and deceleration process, based on the set time constant. The numerical controller then calculates movement of each axis for each interpolation period, based on the command data subjected to the filter processing.
