Danfoss VLT series Programming Guide

MC_MoveRelative with BuerMode = Buered
The potentially ongoing positioning is nished rst. The original target position is reached and the velocity in this target
position is 0. The new target position is the set position of the axis at the point of the rising edge of Execute of the function
block, plus the value of the Distance input of MC_MoveRelative_ISD51x. This means that it is the exact same end position as
with BuerMode = mcAborting_ISD51x.
The trajectory parameters (Velocity, Acceleration, and Deceleration) are only used for the 2
nd
movement.
If the function block is activated in the axis state ContinuousMotion, the specied relative distance is added to the set
position at the point of the rising edge of Execute. This applies both for buer modes Buered and Aborting.
