<div class="markdown_content"><p>Hi, <br/> the MC_MoveVelocity function block is part of the PLC Open motion libraries. Any servo manufacturer has the same FBs with the same interface, adopted to their hardware. A jerk reduction is not part of the interface.<br/> On BoschRexroth servo drives (IndraDrive) there is a parameter to setup jerk reduction, effective on any movement. Check your servo controller, certainly there is such a parameter too.<br/> Rolf</p></div>

<div class="markdown_content"><p>The motion requirements for my servo are most easily accomplished with the MC_MoveVelocity command. Unfortunately, this command in my controller, the Compax3 T40, does not have a jerk input parameter on the function block. Does anyone know of a way to set the jerk with the MC_MoveVelocity function block or perhaps tell me why it was not included as an option in the function block's input?</p></div>
