AXIS_MOVE_VEL
Endless velocity move with a ramped, signed velocity command and InVelocity confirmed from the axis feedback.
When to use it
Use AXIS_MOVE_VEL when an axis runs at a commanded speed with no end position — a conveyor, an unwind, a spindle, a saw feed — and the sequence needs to know the axis is actually AT speed before it commits product to it.
Interface

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.
