PHASE_MATCH_MON
Continuous phase-match supervision while paralleled, with slip-rate trending and pole-slip counting.
When to use it
Use PHASE_MATCH_MON when a machine is already paralleled and its load angle has to be watched for the rest of the run — the synchroniser's job ends at the close, and the angle that was matched at contact is free to walk away afterwards.
Interface

Supervised control write
PHASE_MATCH_MON 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.

Create a free Ri Tech account to download the block. You get the Structured Text body, the Rockwell Add-On Instruction (.L5X), the Schneider Control Expert DFB (.XDB), PLCopen XML, the IEC 61499 function block type (.fbt) and the datasheet.
Every block in the catalogue is free to download, in every format, with no purchase and no card. Browsing needs no account at all; downloading needs a signed-in one, so the block lands in your library and re-downloads whenever you need it.
Source is never published on this page. The implementation is released to a signed-in Ri Tech account — free of charge, but never anonymously.
