SOFT_LOAD_RAMP
Soft loading after breaker close — a rate-limited kW ramp from the machine's present output to its target share.
When to use it
Use SOFT_LOAD_RAMP when a set has just been synchronised and paralleled and must pick up its share of load smoothly, rather than being handed a step change the moment its breaker closes.
Interface
The published port signature. This is the whole of what the block exposes to your program — the implementation body is not shown here and ships with the download.

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.
