Connect SSI/Absolute Encoders to AC500 PLCs via ABB XS305B-E

In a high-speed packaging line, the precise synchronization of a rotary cutter to the continuously moving film is critical. A positioning error of just a few millimeters results in massive material waste and production downtime. Here, the XS305B-E​ is deployed as the critical link. Connected to a high-resolution incremental encoder on the main drive shaft, the board accurately counts every pulse in real-time, providing the AC500 PLC with the exact position and speed of the film web. The PLC uses this data to calculate the precise moment to trigger the cutter via a high-speed output. The XS305B-E​ directly addresses the pain point of accurate, high-speed measurement in noisy industrial environments, enabling closed-loop control for applications like registration, length measurement, and multi-axis synchronization where standard PLC inputs are far too slow. Its value is measured in reduced waste, higher line speeds, and consistent product quality.
