Industrial Applications

1. Dual-Axis Stepper Motor Control for Micro-Conveyors

This application involves precise indexing and speed regulation of small-scale micro-conveyor belts using stepper motors. The CP1E-N14DT1-D utilizes its two built-in 100 kHz pulse outputs to generate high-frequency control signals for dual-axis positioning and synchronized motion of the conveyor drives.

Problem Solved

In small conveyor systems, engineers often struggle with the cost of adding dedicated motion controller modules. This PLC provides high-speed pulse outputs directly on-board, reducing hardware expenses and simplifying the execution of trapezoidal acceleration profiles.

2. Packaging Machine Cut-Off Length Synchronization

In horizontal flow wrappers or bag-making machines, a knife must cut material at precise lengths. By linking a rotary encoder to the PLC's 100 kHz high-speed counter inputs, the controller calculates the exact feeding distance of the packaging film in real-time, driving the cut-off actuator via high-speed transistor outputs.

Problem Solved

Eliminates length errors caused by mechanical slippage of packaging film. By utilizing hardware interrupts linked directly to high-speed counters, the controller responds immediately without being delayed by the standard program scan time.

3. Liquid Filling and Capping Station Control

A compact automatic liquid filling machine requires sensor detection, valve triggering, and a torque-limiting capping process. The 8 inputs receive signals from proximity sensors and bottle-presence photodetectors. The 6 PNP transistor outputs directly actuate low-power pneumatic solenoids and trigger capping spindle drives with precise millisecond-level reaction times.

Problem Solved

Saves panel space and cost by integrating both fast sensor inputs and PNP sourcing outputs on a single compact DIN-rail footprint (86 mm width), while providing solid-state transistor switching that eliminates the wear and tear of relay-based controllers in high-frequency cycling environments.
