IMPORTANT Set travel limits and direction of tuning moves in reference to piston rod starting
position. Leave adequate travel for the piston rod to complete its moves while
tuning.
ATTENTION: Software overtravel must be set prior to initiating the tuning process.
Check the starting position of the piston rod and allow for adequate travel.
Insufficient travel while auto tuning will cause the software overtravel to trigger an
end-stop impact.
ATTENTION: Care should be taken to not exceed the physical travel limits of the electric
cylinder. Doing so will cause the electric cylinder to reach the mechanical end-of-stroke.
Impacting the mechanical end-of-stroke can physically damage the screw and internal
components of the electric cylinder.
