REGEN_BRAKE_MGR
Regenerative braking manager — voltage-tapered line receptivity, rheostatic fallback with a resistor energy budget, and an explicit shortfall.
When to use it
Use REGEN_BRAKE_MGR when electrical braking power has to be disposed of, the contact line may or may not be able to absorb it, and whatever cannot be regenerated or dumped must be handed back to the friction brake rather than assumed gone.

Download REGEN_BRAKE_MGR — free
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.
