Industrial Applications

1. High-Speed Rotary Labeler Positioning

The labeling head in a high-speed beverage bottling line requires precise, repeatable position adjustments. Using the BMXMSP0200's two 200 kHz PTO channels, an engineer can output step/direction commands to Lexium 32C servo drives to position labeling arms with high-speed accuracy.

Problem Solved

Minimizes placement error of labels under varying conveyor speeds. The 200 kHz pulse output ensures high-resolution control of micro-stepping servo drives, reducing position drift and improving label alignment within sub-millimeter tolerances.

2. Precision Metal Strip Shearing Feeder

In a metal fabrication facility, steel strips must be fed to a cutting shear at precise intervals. The BMXMSP0200 module controls the servo-driven pinch rolls using one of its PTO channels, while the proximity sensor and limit switch inputs (Type 3) monitor the origin and material presence directly.

Problem Solved

Direct physical interface with limit switches and origin inputs (response time < 60 µs) bypasses backplane communication lag, preventing material overrun and ensuring precise cutting tolerances at high feed rates.

3. Two-Axis Cartesian Sorting Gantry

A pick-and-place assembly gantry utilizes X and Y axis coordinate movements to sort manufactured parts from a conveyor into bins. The BMXMSP0200 module manages the X and Y axes independently using its 2 channels to deliver synchronized pulse trains to stepper or servo drives.

Problem Solved

Provides cost-effective, multi-axis positioning without requiring a complex, high-cost motion controller card. The robust IP20 construction and wide operating temperature range (-25 to 70 °C) make it suitable for industrial assembly environments with severe temperature fluctuations.
