SE_ATV930_VFD
Schneider Altivar Process 900 (ATV930) CiA 402 drive telegram — control-word state machine, status decode, 0.1 Hz reference scaling and fault-acknowledge sequencing.
When to use it
Use SE_ATV930_VFD when an Altivar Process 900 drive is commanded over a fieldbus and the controller has to assemble the CiA 402 control word, decode the status word, and sequence starting, stopping and fault acknowledge itself.

Supervised control write
SE_ATV930_VFD 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.
