SINUMERIK 840D/SIMODRIVE 611 digital, HLA Module (FBHLA) - 10.03 Edition
The position of the cylinder piston is required for the "Force controller" and "Ve-
locity controller adaptation" functions. 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
Press the "Piston position" soft key (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
Saving the boot file

Menu display "Referencing data for HLA"
Press the "OK" soft key to return to the initial menu display for HLA.
The following machine data affects the position adjustment:
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,
reference point offset or travel direction (MD 32110, MD 34090 or MD 32100) in
the axis-specific machine data is changed.
