Measured position of the
printing or reference index
s_corr
<1> During referencing, only the position setpoint and actual value are
corrected by the same amount in each case. No compensation
movement takes place.
<2> The diagram shows the compensation movement when the printing
index comes too late (printing index actual position < setpoint
position): short-time acceleration. Position setpoint and actual value
are initially both set in the reverse direction in order to adjust the
setpoint to the mechanical system.
<3> The diagram shows the compensation movement when the printing
index comes too late (printing index actual position < setpoint
position): short-time deceleration
