50 ms sampling — what it means for your process
The PXF9AEY2-MVVA1: Self-tuning means the controller auto-adjusts PID parameters on startup — no manual loop tuning for a first-fit installation, though a commissioning engineer will still want to verify the response with a step test on the actual load.
Panel fit — 1/4 DIN footprint
The 96 x 96 mm face (1/4 DIN) fits the standard panel cutout; depth is typical for this class, so check the enclosure depth against the controller body plus wiring clearance behind the panel.
