The position of the cylinder piston is required for functions "Force controller" and
"Velocity controller adaptation". For this purpose, the piston position must be
adjusted once after referencing.
This is done by the following sequence of operations:
S
Reference point approach
S
Select softkey "Piston position" (see Fig. 3-5)
S
Move cylinder piston to limit stop at A end
S
Press softkey "Position adjust." (see Fig. 3-21) to transfer the value set in
MD 5740: ACTUAL_POSITION to MD 5040: PISTON_ZERO.
S
Save boot file
Fig. 3-21 Menu display "Referencing data for HLA"
Select softkey OK to return to the initial menu display for the HLA.
The following machine data are relevant to the adjustment of the piston position:
S
MD 5040: PISTON_ZERO (piston zero in relation to machine zero))
S
MD 5740: ACTUAL_POSITION (actual position in relation to machine zero)
S
MD 5741: ACTUAL_PISTON_POSITION (piston position in relation to piston
zero)
Note
The piston position adjustment must be repeated if the control direction, refer-
ence point offset or travel direction (MD 32110, MD 34090 or MD 32100) in the
axis-specific machine data is changed.
