As per your simulation you are using an Agilus, which cannot rotate A4 infinitely. You can reset the axis by using a PTP movement with not just STATUS, but also TURN, separated by a space, e.g. 010 1100100. Refer to e.g. page 63 of the KUKA Expert Programming Manual. I would get the current axis values from the simulation where you want to "reset" the A4. Then turn the values into 0 and 1 depending if they are >= 0 or not and switch the value for A4. Note the order, according to the manual.
Also note that this is a PTP movement, so robot's tooltip won't stay at the position. Depending on what you are doing it may make sense to move to a safe position before.
