NOTE
l
The cylinder geometry must be configured for the CYL(1) mode
(
see also section "Cylinder configuration" on page 190
).
The position controller is a PI controller. The control dynamics can be set using P
2848 - HYD_PosCon.

Table 7.101: “Hydraulic - position control” parameters
The reference values are generated using the hydraulic motion profile. This
configuration is set up using the motion block table. In this example, table index 0 is
used for position control and table index 1 for speed control. The index is switched
by means of the motion block table using a timer. To do so, the table operating mode
P 2862 - HydOpMode must be set to "Tab(4) = via motion block table". “Tab(2) =
valve control via motion block table” was selected for the valve control P 2840[11] -
CylValueSwSel, meaning that the valve positions must be specified for the
respective table index in the motion block table (P 2863 - Hyd_TabCtrl).
