Hi,
Just after some help with the following issue we are having.
On the Kinetix 5500, if the servo is in motion and the MSF is executed, what does this cause?
We have an issue onsite with a Kinetix 5500 and VPL motor configuration. When the drive goes into fault the code appears to execute this instruction and the load it is moving free wheels for maybe 300mm. When we execute the MSO instruction the drive does an absolute move (MAM) to 0, but now has a physical offset of 300mm but displays 0mm on the faceplate of the drive.
My understanding of this is that the MSF opens the feedback loop and allows the load to be moved by hand, but doesn't track the positioning. And then when the MSO instruction is executed then this closes the loop. If the new position when the MSO is executed is different from when the MSF was executed does this error get corrected when a MAM is executed or would the offset remain?
Looking at what is happening on site, I believe that this is correct and that the offset would remain and not be corrected causing a discrepancy between the physical and software position.
The SI who did the upgrade is looking into this, but I thought I would reach out and try get some further information for them.
Regards
Rob
