50 ms sampling for closed-loop control
The PXF9AEC2-FBVA1: For a temperature loop with a time constant measured in seconds, this sample rate provides adequate PID update bandwidth without aliasing. The self-tuning algorithm adjusts PID parameters automatically during the first heat-up cycle, reducing commissioning time on a new line. If the process has a long dead-time (e.g., ducted air heaters), the auto-tune may settle on conservative gains — manual fine-tuning via the front panel is still possible.
Sourcing and compliance documentation
As a current-lifecycle Fuji Electric controller, the PXF9AEC2-FBVA1 is sourced to order against BOM quantities through authorized distribution channels. Fuji Electric provides standard compliance documentation including RoHS and REACH declarations, plus the product manual with wiring diagrams and installation instructions. The 1/4 DIN form factor follows the standard 96 x 96 mm panel cutout per IEC 61554.
