SE_ATV630_PROCESS
Schneider Altivar Process ATV630 CiA 402 drive telegram with process PI control and sleep/wake — control-word state machine, status decode and 0.1 Hz reference scaling.
When to use it
Use SE_ATV630_PROCESS when an Altivar Process ATV630 drives a pump or fan on a measured process variable (pressure, flow, level) over a fieldbus, and the controller has to close the loop, sleep the pump on low demand, and run the CiA 402 command sequence itself.

Supervised control write
SE_ATV630_PROCESS commands a real actuator. It is written to sit underneath your own interlock, permissive and protection logic — not to replace it. Commission it as you would any control block you wrote yourself.
